24                WinRAR - What's new in the latest version
25
26
27   Version 5.80 beta 1
28   
29   1. "Preserve source files last access time" option on "Time" page
30      of archiving dialog permits to preserve the original last access time
31      of archiving files.
32
33   2. Command line -tsp switch can be used to preserve the original
34      last access time of archiving files. It can be combined with other
35      -ts switches, like: rar a -tsc -tsp arcname files
36
37   3. It is allowed to combine several modifiers in the same -ts switch.
38      For example, we can use -tscap instead -tsc -tsa -tsp.
39
40   4. WinRAR can read default values of command line switches from rar.ini
41      text file, which can be stored either in the same folder as WinRAR.exe
42      or in %APPDATA%\WinRAR folder. This file includes strings in following
43      format:
44
45      switches=<any RAR switches separated by spaces>
46      switches_<command>=<any RAR switches separated by spaces>
47
48      First applies switches to all and second to individual commands.
49      For example:
50
51      switches=-m5 -s
52      switches_x=-o+
53
54      Most of switches specified in rar.ini are used only in the command line
55      mode. Some switches can be applicable both in shell and in command line
56      modes. Previously this rar.ini format was supported only by console RAR.
57
58   5. Command line -agf<default_format> switch specifies the default format
59      string for -ag switch. It has a practical value only if placed to
60      rar.ini configuration file or to RAR environment variable.
61      For example, if we set RAR environment variable to -agfYYYY-MMM-DD,
62      we can use -ag without a parameter with YYYY-MMM-DD format string
63      assumed.
64
65   6. Switches -ed and -e+d can be used in archive processing commands
66      for any combination of RAR and archive operating systems.
67      In older versions RAR for Windows could not use them for Unix RAR
68      archives also as RAR for Unix for Windows RAR archives.
69
70   7. Previously "Test" command failed to check integrity of archived NTFS
71      alternate data streams and issued "Unknown data header format" warning
72      if size of such stream exceeded 16 MB. This limitation is removed now.
73
74   8. Archiving speed for large NTFS alternate data streams on multi-core
75      CPUs is increased.
76   
77   9. "Find" command:
78
79      a) when extracting encrypted files directly from "Search results"
80         dialog, password prompt was issued for every found file
81         even if all files belonged to same archive.
82
83         Now password is requested only once per archive;
84
85      b) Ctrl+A hotkey selects all files in "Search results".
86
87  10. Archive comment window:
88
89      a) previous versions did not allow to use Ctrl+W shortcut to close
90         WinRAR when comment window had keyboard focus. Now Ctrl+W works
91         also from comment window;
92
93      b) mouse wheel is supported also for comments with ANSI Escape sequences;
94      
95      c) for some lenghty comments with ANSI Escape sequences last line
96         of comment was visible only partially even after scrolling up to
97         bottom. It is displayed comletely now.
98
99  11. Maximum path length for files in 7z archives is increased up to
100      2048 characters. While such lengthy paths were already supported
101      for RAR and ZIP formats, previous versions limited the path length
102      to 260 characters for 7z archives.
103
104  12. If archive or file name is too lengthy to fit to archiving
105      or extraction progress window, it is truncated. Previously such names
106      were truncated at the end, making the file extension invisible.
107      This version truncates them removing the path component and symbols
108      in the middle, but preserving beginning of file name and file extension.
109
110  13. If files selected for archiving differ only by extension,
111      a proposed archive name is based on their name part.
112      For example, archiving dialog will propose Readme.rar if we selected
113      Readme.txt and Readme.doc.
114
115      Previous versions always generated the archive name based on parent
116      folder name for several selected files.
117
118  14. "Symlink" and "Hardlink" is diplayed in "Type" column for symlink
119      and hardlink records in .tar archives. Previous versions displayed
120      a proper type for such records only in .rar archives.
121         
122  15. Copying and pasting files from large archives could fail if
123      extraction took a lot of time. This version can paste files from
124      such archives as well, but we have to start extraction already on
125      "Copy" command and not on "Paste" to achieve this.
126   
127  16. Similarly to RAR5 volumes, recovery volumes in RAR4 format use
128      the same width of volume number field as corresponding RAR volumes.
129      While previously WinRAR could create arc.part01.rar and arc.part1.rev
130      in RAR4 format, now both types of volumes will use "part01".
131
132  17. "Set font..." button in "Settings/File list" also changes the folder
133      tree panel font. Previously it changed only the file list font.
134
135  18. Bugs fixed:
136
137      a) if non-existent path is specified in archive name in archiving
138         dialog, WinRAR proposes to create such path. Previous versions
139         could create such path in WinRAR start-up folder instead of
140         currently displayed folder;
141
142      b) WinRAR could crash when adding the recovery record in RAR5 format
143         on CPUs not supporting CPUID EAX=7 command and returning random
144         data in response. These are some CPUs from early 2000s;
145
146      c) WinRAR failed to create archives after dragging files with
147         right mouse button in Windows shell, dropping them to another folder,
148         selecting "Add to archive..." in context menu and enabling
149         "Put each file to separate archive" option;
150
151      d) "winrar r *.zip" command repaired only the first ZIP archive
152         in the set if all archives had numeric names like 1.zip, 2.zip
153         and signatures in the beginning of archives were missing;
154
155      e) previous WinRAR version failed to unpack folder records
156         in archives created by RAR 1.50;
157      
158      f) in rare cases WinRAR failed to extract and reported an error
159         for valid .gz archives produced by some compression optimization
160         tools;
161
162      g) progress bar in tray icon never reached 100% in high DPI mode;
163
164      h) creation and last access time was not displayed for archived folders
165         if folder records were stored in archive after folder contents;
166
167      i) "Skip encrypted archives" option in "Convert archives" command
168         did not work for 7-Zip archives with headers encryption.
169
170
171   Version 5.71
172   
173   1. "Convert archives" command:
174
175      a) improved performance when processing a lot of small archives
176         in Windows 10;
177
178      b) fixed memory leaks which could lead to excessive memory use
179         when converting to ZIP format.
180
181   2. Corrupt ZIP archive processing:
182
183      a) "Repair" command replaces packed and unpacked file sizes stored
184         in local file header with sizes from central directory
185         if local header sizes look invalid;
186
187      b) file extraction is stopped at unpacked size stored in ZIP headers
188         even if available packed data allows further extraction.
189         It is done to prevent unexpected hard drive space usage.
190
191   3. Ctrl+C allows to abort RAR "l" command quickly. In previous versions
192      it could take several seconds until list command stopped.
193
194   4. Bugs fixed:
195
196      a) WinRAR could crash when attempting to display some types of archive
197         comments in GUI shell, resulting in a denial of service;
198
199      b) if "Save archive name" and "Add to context menu" options were
200         set in compression profile parameters and profile was invoked
201         from Explorer context menu, WinRAR proposed an automatically
202         generated archive name instead of name saved in profile.
203
204      c) WinRAR displayed an unneeded pair of round brackets in "Archive"
205         column of "Diagnostic messages" window for system error messages;
206
207      d) "Extract to folder\" Windows Explorer context menu command could
208         fail to unpack ZIP archives if their names included a numeric 
209         part followed by .zip extension, arbitrary data was present
210         before the first file record and "Remove redundant folders from
211         extraction path" WinRAR option was switched on;
212
213      e) in "RAR x -x<mask> arcname" command, parent folders of files
214         matching the specified mask also were excluded from extracting;
215
216      f) "Find" command returned the current folder own name additionally
217         to its contents for "Current folder" search area if folder name
218         matched "File names to find" mask;
219
220      g) if "Find in files" and "Find in archives" are both enabled,
221         "Find" command did not match an archive name itself against
222         "File names to find" mask after searching inside of archive.
223         So it did not display archive names for masks like *.rar 
224         and applied this mask only to files inside of archives;
225
226      h) when running an executable directly from archive, WinRAR 5.70
227         did not set a temporary folder with unpacked files as current.
228         So executables attempting to access other archived files
229         in current folder could fail to work;
230
231      i) WinRAR could be inaccessible for few seconds after closing
232         an archived file opened in internal viewer in Windows 10;
233
234      j) dragging a file to subfolder of ZIP archive with "Store full paths"
235         option enabled produced invalid pathnames consisting of repeated
236         subfolder name. Same invalid pathnames were produced if adding files
237         to ZIP archive with -ap<folder> -ep2 switches.
238
239   
240   Version 5.70
241
242   1. "Files to process" option on "Time" page of archiving dialog
243      allows to choose files based on modification, creation or last access
244      file time. Previously it was possible for modification time only.
245   
246   2. Command line -ta, -tb, -tn, -to switches accept 'm', 'c' and 'a'
247      modifiers after the switch name. So file time conditions can include
248      not only the file modification time as in previous versions,
249      but also creation and last access time.
250
251      Such switch can include multiple modifiers to set the same date
252      for all specified times. For example, -tamc20190215 will process files
253      modified and created after 2019-02-15. 
254      
255      New 'o' modifier permits to switch from AND to OR logic,
256      so -tamco20190215 includes files modified or created after 2019-02-15.
257      It is also allowed to specify several time filtering switches
258      with different dates in the same command line, like:
259      -taco20190201 -tbmo20190210
260
261      Switches -ta and -tn also include files matching the specified date
262      exactly. Switches -tb and -to exclude such files.
263
264   3. WinRAR file list can display creation and last access file times
265      if they are available.
266
267      Creation and last access columns are disabled by default and can be
268      enabled in "Select file list columns" dialog. This dialog is opened
269      after right clicking on file list column headers or after pressing
270      "File list/Files/Columns..." button in WinRAR settings.
271
272   4. "Double extensions for archives" and "Archives in subfolders"
273      options on "Files" page of archiving dialog modify behavior of 
274      "Put each file to separate archive" option.
275
276      You can switch between archive names in filename.ext.rar
277      and filename.rar style with "Double extensions for archives".
278
279      You can create a separate archive for every file in selected subfolders
280      or store the entire contents of every selected folder in separate
281      archive depending on the state of "Archives in subfolders" option.
282
283   5. New -ad1 switch can be used when unpacking multiple archives
284      recursively, such as 'rar x -r -ad1 arc\*.rar'. It creates
285      a separate folder for files unpacked from each archive,
286      but unlike already existing -ad switch, it creates such folders
287      in each archive folder.
288
289   6. If context menu "Extract each archive to separate folder" is applied
290      to archives from different folders in Windows Explorer "Search results",
291      subfolders with unpacked files are created in each archive folder.
292      Previous versions created them all in a folder of right clicked archive.
293   
294   7. New "File list/List style/Checkboxes" option in WinRAR settings
295      allows to use checkboxes to select file list items.
296
297   8. New "File list/Files/Exact sizes" option in WinRAR settings.
298
299      If this option is on, file sizes are always displayed in bytes.
300      If it is off, sizes are rounded up and use units such as KB or MB.
301      Smaller files can be still displayed in bytes.
302
303   9. If several console RAR are started with -ioff switch, PC is turned off
304      by RAR copy finished last. Previously this switch was processed
305      by first finished copy.
306
307  10. Read and write buffer size is increased for .iso files.
308      It can help to improve .iso extraction performance in some cases,
309      such as for network drives.
310
311  11. If "Delete archive" option in extraction dialog is applied to a set
312      of RAR and REV volumes in volname.part# format, WinRAR will delete
313      REV volumes as well. Previously only RAR volumes were deleted
314      keeping REV files intact.
315
316  12. If "Delete archive" option in extraction dialog is applied to set
317      of ZIP volumes with .zip.001, .zip.002, .zip.003 extensions,
318      WinRAR will delete all ZIP volumes. Previously only .zip.001 volume
319      was deleted for such volume naming scheme.
320
321  13. If we unpack arcname.rar using "Extract to arcname\" Explorer context
322      menu command and "arcname" file already exists, WinRAR shell extension
323      will propose "Extract to arcname~1\" instead. Previously this context
324      menu command attempted to create a folder with same name as already
325      existing file and failed.
326
327  14. If we pack a shortcut file with .lnk extension from Explorer context
328      menu, .lnk file itself is added to archive. Previous versions added
329      .lnk file target instead of .lnk file.
330
331  15. Windows does not allow executables exceeding 4 GB, so WinRAR issues
332      an error immediately when attempting to create 4 GB or larger
333      RAR SFX volumes. Previously WinRAR issued such error only after
334      creating the first RAR volume.
335
336  16. Total extraction progress is displayed for 7z multivolume archives. 
337      Accuracy of 7z total extraction progress is improved.
338
339  17. "Find" command "Disks and folders" drop down list has been renamed
340      to "Search area". Additionally to already existing choices,
341      it includes a new "Selected items" option restricting search
342      to files and folders selected in WinRAR file list.
343
344  18. "Find" command displays the number of found items in status bar.
345
346  19. "Diagnostic messages" window displays archive names in a separate
347      column to provide the better message visibility for lengthy
348      archive names.
349   
350  20. Switch -isnd[-] in command line WinRAR mode allows to override
351      "Enable sound" option in WinRAR settings. Use -isnd to turn sound
352      notifications on and -isnd- to turn them off.
353
354  21. Nadav Grossman from Check Point Software Technologies informed us
355      about a security vulnerability in UNACEV2.DLL library.
356      Aforementioned vulnerability makes possible to create files
357      in arbitrary folders inside or outside of destination folder
358      when unpacking ACE archives.
359
360      WinRAR used this third party library to unpack ACE archives.
361      UNACEV2.DLL had not been updated since 2005 and we do not have access
362      to its source code. So we decided to drop ACE archive format support
363      to protect security of WinRAR users.
364
365      We are thankful to Check Point Software Technologies for reporting
366      this issue.
367   
368  22. Bugs fixed:
369
370      a) console RAR mixed up source and destination file sizes and times
371         in the overwrite prompt when updating a file in RAR archive
372         with -o switch;
373
374      b) dragging files from 32-bit applications to 64-bit WinRAR window
375         did not work;
376
377      c) WinRAR Shift+Del command applied to a folder could fail to delete
378         some its subfolders. This command is used to delete files and folders
379         permanently instead of moving them to Recycle Bin;
380
381      d) folder tree panel could not change folders if archived pathnames
382         started from path separator, such as in archives created by tar tool
383         with --absolute-names option;
384
385      e) if relative "Path=.\somefolder" was specified in SFX comment
386         and SFX archive needed to elevate privileges when extracting,
387         it created 'somefolder\somefolder' instead of 'somefolder';
388
389      f) commands modifying an existing RAR4 volume reset the volume number
390         field to 1. While it did not affect extraction, WinRAR displayed
391         a wrong volume number for such volumes;
392
393      g) fixed a crash when reading a comment from a corrupt RAR file;
394
395      h) toolbar in "Find" command "Search results" window was not adjusted
396         to different toolbar icon sizes properly.
397
398
399   Version 5.61
400
401   1. "Delete archive" extraction option deletes all volumes even if user
402      started extraction from non-first RAR volume, but first volume
403      is present and all files are unpacked successfully. In such case
404      previous versions ignored "Delete archive" even if WinRAR was able
405      to locate the first volume and process the volume set from beginning.
406   
407   2. Compression ratio bar is not displayed on "Archive" page of
408      Explorer file properties for archives with encrypted file names.
409      WinRAR cannot reliably calculate it for such archives without
410      a password and previously it just displayed 0% here.
411   
412   3. Bugs fixed:
413
414      a) WinRAR displayed "The specified password is incorrect" message
415         infinitely when attempting to open RAR5 archive with encrypted
416         file names if wrong global password was set with Ctrl+P;
417
418      b) memory management bug in the password dialog could lead to
419         access to already freed memory followed by crash.
420         This issue may be also associated with security risks;
421
422      c) fixed crashes in corrupt RAR, ACE and LZH archives.
423         This issue may be also associated with security risks;
424
425      d) while starting, WinRAR could cause a brief flickering in menu bars
426         of few other applications;
427
428      e) WinRAR "Find" command matched "String to find" against all
429         archived files ignoring "File names to find" mask when searching
430         in CAB archives;
431
432      f) SFX module "License" command did not set a title of license window;
433
434      g) if "Start-up folder" in WinRAR settings included the trailing
435         backslash, WinRAR ignored first "Up one level" command.
436         
437
438   Version 5.60
439
440   1. We updated WinRAR graphics.
441
442      We are grateful to http://weirdsgn.com and http://icondesignlab.com
443      designers participated in this endeavor and proud to announce that
444      WinRAR uses the new icon set prepared by Aditya Nugraha Putra
445      from http://weirdsgn.com.
446
447      Previous WinRAR icons are available as interface theme here:
448      https://rarlab.com/themes/WinRAR_Classic_48x36.theme.rar
449   
450   2. "Repair" command efficiency is improved for recovery record protected
451      RAR5 archives. Now it can detect deletions and insertions of unlimited
452      size also as shuffled data including data taken from several recovery
453      record protected archives and merged into a single file in arbitrary
454      order.
455   
456   3. "Turn PC off when done" archiving option is changed to "When done"
457      drop down list, so you can turn off, hibernate or sleep your PC
458      after completing archiving.
459
460   4. Use -ioff or -ioff1 command line switch to turn PC off,
461      -ioff2 to hibernate and -ioff3 to sleep your PC after completing
462      an operation.
463
464   5. If encoding of comment file specified in -z<file> switch is not
465      defined with -sc switch, RAR attempts to detect UTF-8, UTF-16LE
466      and UTF-16BE encodings based on the byte order mask and data
467      validity tests.
468
469   6. WinRAR attempts to detect ANSI, OEM and UTF-8 encodings of
470      ZIP archive comments automatically.
471   
472   7. "Internal viewer/Use DOS encoding" option in "Settings/Viewer"
473      is replaced with "Internal viewer/Autodetect encoding".
474      If "Autodetect encoding" is enabled, the internal viewer attempts
475      to detect ANSI (Windows), OEM (DOS), UTF-8 and UTF-16 encodings.
476
477   8. Normally Windows Explorer context menu contains only extraction
478      commands if single archive has been right clicked. You can override
479      this by specifying one or more space separated masks in "Always display
480      archiving items for" option in Settings/Integration/Context menu items",
481      so archiving commands are always displayed for these file types
482      even if file was recognized as archive. If you wish both archiving
483      and extraction commands present for all archives, place "*" here.
484   
485   9. SFX module "SetupCode" command accepts an optional integer parameter
486      allowing to control mapping of setup program and SFX own error codes.
487      It is also accessible as "Exit code adjustment" option
488      in "Advanced SFX options/Setup" dialog.
489   
490  10. New "Show more information" WinRAR command line -im switch.
491      It can be used with "t" command to issue a message also in case of
492      successful archive test result. Without this switch "t" command
493      completes silently if no errors are found.
494
495      This switch is applicable only to WinRAR.exe and ignored by console
496      RAR.exe.
497
498  11. If a wrong password is entered when unpacking an encrypted file
499      in ZIP archive, WinRAR proposes to enter a valid password
500      for same file again instead of aborting extraction.
501
502  12. If a wrong password is entered when opening or unpacking RAR archive
503      with encrypted file names, WinRAR proposes to enter a valid password
504      again instead of aborting the operation. Previous versions already
505      did so for RAR archives with encrypted file data, but aborted
506      for archives with file name encryption.
507
508  13. WinRAR recognizes GZIP files with arbitrary data preceding
509      an actual GZIP archive, such as .scexe firmware files.
510
511  14. @filelist parameter can be specified in "Files to add" field of
512      archiving dialog. In this case WinRAR will attempt the list of archiving
513      files from 'filelist' file, which should be the plain text, one file
514      name per line.
515
516  15. Info dialog:
517      
518      a) compression ratio graph is updated;
519
520      b) "Names and data" is displayed in "Encryption" field for
521         archives with encrypted file names.
522
523  16. Full archive name is displayed if mouse pointer is placed over
524      an archive name in the operation progress window. It can be useful
525      if archive name is lengthy and does not fit to available window space.
526
527  17. If -ts1 switch is used with -u or -f, file time comparison is performed
528      with 1 second precision. Previosuly in such case we could wrongly treat
529      an adding file as newer than archived just because we compared the high
530      precision adding file time against the low precision archived file time.
531
532  18. "Update" and "Fresh" commands ('u' and 'f' in the command line mode)
533      quit immediately if no files are to be updated. Previously they created
534      a temporary archive before quitting when updating archives with recovery
535      record or quick open information.
536
537  19. Prompt is issued after creating 500 volumes from WinRAR GUI shell,
538      so user can continue or quit further archiving. It is done to prevent
539      creating many thousands of volumes in case of wrongly entered
540      volume size.
541
542  20. WinRAR uses megabytes instead of bytes as default units for volume size
543      field in the archiving dialog.
544
545  21. "Repair" command issues "Recovery record is corrupt" message
546      after repairing RAR5 archive containing a broken recovery record.
547      Previously such message was issued only by "Test" command
548      and "Repair" handled most of recovery record damages silently.
549
550  22. Bugs fixed:
551
552      a) fixed potential security issues when processing corrupt
553         RAR archives;
554      
555      b) non-English characters in TAR files with PAX extended headers
556         were not displayed correctly;
557
558      c) "rar x arcname.rar .." command unpacked files to current folder
559         instead of its parent;
560
561      d) pasting files from Windows Explorer to archive opened in WinRAR
562         blocked further copy and paste operations in Explorer until
563         archiving was finished;
564
565      e) SFX module issued "The specified password is incorrect" message
566         infinitely not prompting for correct password once a wrong password
567         was entered;
568
569      f) folders time was always set when extracting ZIP archives even if
570         "File time" options in the extraction dialog were turned off;
571
572      g) if "Delete archive: Always" was selected when extracting
573         and user pressed "Cancel" in the file overwrite or password prompt,
574         an archive could be deleted even after cancelling extraction
575         for .zip and .7z formats.
576
577   
578   Version 5.50
579
580   1. WinRAR and command line RAR use RAR 5.0 archive format by default.
581      You can change it to RAR 4.x compatible format with "RAR4" option
582      in archiving dialog or -ma4 command line switch.
583      
584      If you prefer RAR 4.x format by default, use "Create default..."
585      button on "Compression" page of WinRAR settings and set "RAR4"
586      in the displayed dialog.
587
588      This change affects only new clean installs. If you already saved
589      RAR format in the default compression profile in previous versions,
590      WinRAR respects stored settings.
591   
592   2. Use "Set master password" button in "Organize passwords" dialog
593      to encrypt saved password records and protect them from unauthorized
594      access. 
595      
596      If saved passwords are protected with master password, you need to
597      enter the master password and press "OK" in password prompt to access
598      them. If entered password does not match the master password,
599      it is treated as a usual password for archive operations.
600
601      Once entered, the master password is valid until WinRAR is closed.
602      Close WinRAR and open it again after specifying the master password
603      if you wish to see how protection works. Enter a valid and then
604      empty master password to remove encryption from previously protected
605      password records.
606
607      This WinRAR version uses a new data format for password organizer,
608      so passwords stored in "Organize passwords" dialog are not readable
609      by older versions. It does not affect archive encryption formats
610      and encrypted archives are compatible with previous WinRAR version.
611      Organizer data is converted to a new format only when you save it
612      and not immediately after installing WinRAR.
613
614   3. Prompt proposing to set the master password is displayed
615      when storing a password in compression profile. You can enter
616      the master password to encrypt password data stored in Registry
617      and protect it from unauthorized access. You will need to enter
618      the master password in password prompt dialog to access
619      such compression profile after that.
620
621      Once entered, the master password is valid until WinRAR is closed.
622      Close WinRAR and open it again after specifying the master password
623      if you wish to see how protection works.
624
625   4. By default, WinRAR uses AES-256 in CTR mode to encrypt ZIP archives.
626      While AES-256 is significantly more secure than ZIP 2.0 legacy
627      encryption algorithm, it can be incompatible with some older
628      unzip software. If compatibility with such tools is required,
629      you can enable "ZIP legacy encryption" option in the password
630      dialog or use -mezl switch in the command line mode. 
631   
632   5. Added extraction support for .LZ archives created by Lzip compressor.
633   
634   6. Modern TAR tools can store high precision file times, lengthy
635      file names and large file sizes in special PAX extended headers
636      inside of TAR archive. Now WinRAR supports such PAX headers
637      and uses them when extracting TAR archives.
638
639   7. New "Store modification time" option on "Time" page of archiving
640      dialog can be used to prohibit storing the file modification time
641      in RAR 5.x archives. Former "High precision modification time"
642      option is replaced by "High precision time format".
643
644   8. New "Full paths in title bar" option in "Settings/General" dialog.
645      If enabled, the full path of currently opened folder or archive
646      is displayed in WinRAR title bar.
647
648   9. New "File types to open as archives first" option
649      in "Settings/Compression". Here you can define how Enter
650      or double click on a file with non-archive extension and archive
651      contents should be processed in WinRAR file list in file
652      management mode. Examples of such files are .docx or self-extracting
653      .exe archives. You can instruct WinRAR either to open such files
654      as archives first or to execute or open them in associated programs.
655
656      Default settings are to open self-extracting exe and to run
657      other types of archives with non-archive extension.
658
659      Regardless of these options, you can always open any such 
660      archive file by pressing Ctrl+PgDn on its name in WinRAR file list.
661
662      Default folders for archives and extracted files are moved
663      from "Settings/Compression" to "Settings/Paths".
664
665  10. New "Copy full names to clipboard" command in "File" menu
666      places full names of selected files to clipboard.      
667
668  11. Changes in the context menu displayed when right clicking
669      the file list in WinRAR:
670
671      a) several commands, which are also present on the toolbar
672         or in main menu, such as "View" and "Repair", are removed
673         from this context menu;
674
675      b) "Copy full names to clipboard" command is added;
676
677      c) "Run" for executables, "Open in associated application"
678         for associated files and "Show archive contents" for archives
679         are added. They allow to choose a way to process SFX archives
680         and archive files with non-archive extensions.
681
682         These items are present only in the file management mode
683         and are not available inside of archives.
684
685  12. LZ and ZIPX are added to list of associations in Settings/Integration
686      dialog.
687
688  13. LZ and ZIPX extensions are added to default list of formats for
689      -ms switch ("Specify file types to store") invoked without parameters.
690
691  14. You can specify 'f' charset value in -sc switch to use UTF-8
692      encoding. For example:
693
694      rar a -scfl arcname @filelist.txt
695
696      to read contents of filelist.txt as UTF-8 text.
697
698  15. RAR "lt" and "vt" commands display file times with nanosecond
699      precision. Such precision is used in RAR5 archives created
700      by RAR/Unix 5.50 and newer. Archives created by WinRAR have 100ns
701      file time precision.
702
703  16. Only '+', '-' and '1' precision modifiers are supported
704      in -ts switch now. Use '+' to store the file time with maximum
705      precision, '-' to omit the file time and '1' to store it with
706      1 second precision. Intermediate precision modes previously
707      defined with '2' and '3' modifiers are not available in RAR 5.0
708      archive format and ignored by -ts switch.
709
710  17. If a wrong password is entered when unpacking an encrypted file
711      in RAR5 archive, WinRAR proposes to enter a valid password
712      for same file again instead of aborting extraction.
713   
714  18. File path information is displayed if mouse pointer is placed over
715      a name of archiving file in the operation progress window.
716
717  19. Name of currently active compression profile is displayed
718      in the archiving dialog above "Profiles..." button.
719
720  20. If "Find" command is invoked from inside of archive subfolder,
721      "File names to find" will include the path to this subfolder.
722      So "Find" will search only starting from this subfolder.
723
724  21. Bugs fixed:
725   
726      a) fixed crashes and security vulnerability when unpacking corrupt
727         RAR archives;
728
729      b) WinRAR failed to unpack files in ZIP archives compressed
730         with XZ algorithm and encrypted with AES;
731      
732      c) if "Windows progress bars" option in WinRAR settings was turned off
733         and "Put each file to separate archive" archiving mode was used,
734         "gold" part of total progress bar did not display the compressed
735         data ratio correctly;
736
737      d) SFX archive extraction progress was incorrect in case of
738         multivolume SFX archive with total volume size exceeding 4 GB;
739
740      e) if archived folder name included trailing spaces, if user
741         selected and extracted some folders in non-root archive folder
742         and if "Allow potentially incompatible names" extraction option
743         was turned off, WinRAR could lose one or more leading characters
744         in extracted folder name;
745
746      f) if only creation or only last access file time was stored in RAR5
747         archive with 1 second precision, such as with -ma5 -tsm- -tsa1
748         switches, this stored time was ignored when extracting.
749
750
751   Version 5.40
752
753   1. "Name encoding" submenu in "Options" menu allows to select
754      encoding for archived file names. This selection affects archive
755      browsing and extraction commands. You can use Ctrl+E keyboard
756      shortcut to access this menu quickly.
757
758      It can be useful when unpacking an archive without Unicode file names.
759      For example, unpacking a zip file with Chinese archived names
760      in Windows with Russian specified as a language for non-Unicode
761      programs.
762
763   2. If RAR recovery volumes (.rev files) are present in the same folder
764      as usual RAR volumes, archive test command verifies .rev contents
765      after completing testing .rar files.
766
767      If you wish to test only .rev files without checking .rar volumes,
768      you can select .rev files in WinRAR file list and apply "Test"
769      only to them or run:
770
771      rar t arcname.part1.rev
772
773      in the command line.
774
775   3. While NTFS file system permits file names with trailing spaces
776      and dots, a lot of Windows programs fail to process such names
777      correctly. If "Allow potentially incompatible names" option
778      in "Advanced" page of extraction dialog is turned off, WinRAR removes
779      trailing spaces and dots, if any, from file names when extracting.
780
781      This option is turned off by default.
782
783      Command line RAR also removes trailing spaces and dots when extracting
784      unless -oni switch is specified.
785   
786   4. Previously "Synchronize archive contents" update mode
787      (-as command line switch) aborted if some of archiving folders
788      could not be read. Now WinRAR continues performing the operation
789      and preserves archived files matching unreadable folders.
790
791   5. WinRAR Shift+Del delete command can be used to delete folders
792      containing non-standard file names with trailing spaces and dots.
793      Usual delete to Recycle Bin also as Shift+Del in previous WinRAR
794      versions cannot delete such folders.
795
796      Unlike Del command, Shift+Del removes files permanently,
797      they are not moved to Recycle Bin. No additional prompts are issued
798      for files with read-only and system attributes.
799
800   6. You can drag folders from folder tree panel and drop them to
801      other programs or Desktop to copy or unpack them. Drag the archive
802      icon in tree panel root to unpack the entire archive.
803   
804   7. "New folder" button in extraction dialog proposes a new folder name
805      based on archive name instead of generic "New Folder".
806
807   8. Command line RAR version information:
808   
809      a) if -iver switch is specified, RAR displays the version number
810         and quits. You can run just "RAR -iver";
811
812      b) "x86" or "x64" is displayed in Windows RAR version information
813         both for -iver and in the copyright title for other commands.
814   
815   9. If -p switch is used without optional <pwd> parameter,
816      a password can be also set with file redirection or pipe.
817
818      For example: rar -p myarc.rar myfiles < psw.txt
819
820  10. Command line RAR treats 'arcname.partN' as 'arcname.partN.rar'
821      if 'arcname.partN' does not exist and 'arcname.part#.rar' exists.
822
823      For example, it is allowed to run:
824
825      RAR x arcname.part01
826
827      to start extraction from arcname.part01.rar
828   
829  11. Improvements in 7z archives support:
830   
831      a) "Solid" status is correctly detected and reported for 7z archives
832         in WinRAR "Info" command;
833
834      b) dictionary size is displayed for LZMA and LZMA2 7z archives
835         in WinRAR "Info" command;
836
837      c) unknown packed size for files inside of 7z solid block is denoted
838         as '?' instead of '0' when browsing the archive contents in WinRAR.
839   
840  12. Maximum comment length for RAR archives is increased from 64 to 256 KB.
841
842      Since SFX script commands are stored in archive comment,
843      it allows a longer main and license text in SFX archives.
844
845  13. Size of default WinRAR viewer font is scaled up properly
846      in Windows high DPI mode.
847
848  14. Switch -scul can be used to process big endian UTF-16 list files
849      as well, provided that they have a correct byte order mark.
850      Previously it allowed only little endian file lists.
851
852  15. Minimum supported Windows version is Windows XP SP3 now.
853      WinRAR will not run in Windows XP without service packs.
854
855  16. "Settings/File list/Allow all uppercase names" option is removed.
856      This option was intended to simplify transition from MS DOS to
857      Windows and is not needed anymore.
858
859  17. Bugs fixed:
860   
861      a) WinRAR 5.31 x64 "Compress and email" command did not work
862         with Microsoft Outlook x64;
863
864      b) if WinRAR 5.31 version for one of right to left languages
865         was installed in Windows with English or other not right to
866         left system language, WinRAR could change Windows Explorer
867         layout to right to left;
868
869      c) if archive was stored in a folder without "Write" permission
870         and if archive contents was extracted with drag and drop to
871         a writable folder, WinRAR issued an unnecessary privileges
872         elevation prompt.
873
874   
875   Version 5.31
876
877   1. Following issues are corrected in Windows high DPI mode:
878
879      a) if text size in Windows settings was set to 150% or larger,
880         the font size in WinRAR help was not increased accordingly,
881         resulting in too small text;
882
883      b) default columns width in WinRAR file list was less
884         than expected for 125% or larger Windows text setting.
885
886   2. Interface improvements for right to left languages:
887
888      a) proper text alignment in simple WinRAR prompts, such as
889         confirmations to delete archived files or to clear the log file;
890
891      b) "OK", "Cancel", "Help" buttons in multi-page dialogs,
892         such as archiving and extraction options or WinRAR settings,
893         are aligned correctly and translated to default Windows
894         display language.
895
896   3. Bugs fixed:
897
898      a) WinRAR SFX module could load DLL libraries from its own executable
899         folder as a result of calling some Windows API functions.
900         It could lead to security threat if DLL files with malicious code
901         were stored in the same folder as SFX archive. Now SFX module
902         takes additional steps to prevent such situation in Windows Vista
903         and newer.
904
905         Be aware that users without latest Windows security patches
906         installed also as Windows XP users still can be affected,
907         so they must be especially careful to run SFX archive from
908         a folder without suspicious DLL files;
909      
910      b) WinRAR 5.30 failed to run .lnk files from file list.
911
912   
913   Version 5.30
914
915   1. Information about the critical vulnerability in WinRAR self-extracting
916      archives published in news in September and October 2015 is incorrect.
917      Unfortunately mass media failed to recognize that what was described
918      as WinRAR vulnerability is Windows OLE vulnerability patched
919      in November 2014:
920
921      https://technet.microsoft.com/en-us/library/security/ms14-064.aspx
922
923      Even if unpatched, this Windows OLE vulnerability does not introduce
924      new risk factors for WinRAR SFX archives.
925
926      Please read http://rarlab.com/vuln_sfx_html2.htm for more details.
927
928      No patches for WinRAR are needed.
929
930   2. Added extraction of multipart ZIP archives created by 7-Zip.
931      Such archives have .zip.001, .zip.002, ... file extensions.
932      You need to open .zip.001 file in WinRAR shell to browse 
933      or unpack such archive. All parts must be stored in the same folder
934      before starting extraction.
935
936   3. Added extraction of files split to multiple parts with .001,
937      .002, ..., extensions. You can open .001 file as a usual archive
938      and then unpack its contents. WinRAR will combine all parts
939      and save them to extracted file. All parts must be stored
940      in the same folder before starting extraction.
941
942      "001" item is included to "Associate WinRAR with" list
943      in "Settings/Integration" dialog.
944         
945   4. WinRAR file list allows to use mouse Back and Forward buttons
946      or Alt+Left and Alt+Right keyboard shortcuts to navigate
947      in recently visited folders.
948
949   5. Folder wildcards are allowed in RAR command line in file names to
950      archive. For example:
951
952      rar a backup c:\backup\2015*\*
953
954      will archive all '2015*' folders in c:\backup. Use -r switch to search
955      for '2015*' also in c:\backup subfolders.
956
957   6. "Extract" button in SFX archive is changed to "Pause" when extraction
958      is started, so it is possible to pause SFX extraction and resume it
959      later.
960
961   7. "Skip encrypted" option in "Find files" dialog to silently skip
962      encrypted archives while performing search command.
963   
964   8. Archive test command works for tar.gz, tar.bz2 and tar.xz archives.
965      Since TAR format does not provide file data checksums, WinRAR checks
966      only validity of GZIP, BZIP2 or XZ container.
967   
968   9. Adding a new string to WinRAR diagnostic messages window could be
969      slow and affect the operation performance in case of thousands
970      of errors. Now it works fast regardless of errors number.
971
972  10. New 'R' object for -sc switch defines encoding of console
973      RAR messages sent to redirected files and pipes. For example:
974
975      rar lb -scur data > list.txt
976
977      will produce Unicode list.txt with archived file names.
978
979  11. Sleep time parameter in -ri<priority>[:<sleep_time>] switch is
980      adjusted to lower its impact to RAR performance and especially
981      to recovery record related operations. Higher sleep time values
982      are needed to reduce the system load to same level as
983      in previous versions.
984
985  12. Console RAR "l" and "v" commands display file time in YYYY-MM-DD
986      format.
987
988  13. When extracting RAR and ZIP archives created in Unix, WinRAR maps
989      decomposed Unicode characters to precomposed. Such conversion
990      is required for some Unix and OS X archives to correctly unpack
991      non-English archived names in Windows. It works for Windows versions
992      starting from Windows Vista.
993
994  14. Modification time is set for all folders created when unpacking
995      .7z archives. Previous versions set it only for non-empty folders.
996
997  15. WinRAR prevents a computer to go to sleep by inactivity timeout
998      until current operation, such as archiving, extraction or another
999      archive processing, is done.
1000
1001  16. Total progress bar is displayed when extracting .arj, .lzh and .cab
1002      archives (except multivolume archives).
1003
1004  17. Progress bar is displayed when deleting files after archiving
1005      and when clearing "Archive" attribute of archived files.
1006
1007  18. "Test" command also verifies contents of NTFS alternate data streams
1008      in RAR 3.x - 5.x archives. Previously their contents was checked
1009      only during extraction command.
1010
1011  19. SFX module sets sfxstime environment variable, which contains
1012      the module start time in "YYYY-MM-DD-HH-MM-SS-ms" format.
1013      You can specify it in Path command if you need to generate a time
1014      based unique installation path, such as "Path=myapp-%sfxstime%".
1015
1016  20. Bugs fixed:
1017
1018      a) console RAR crashed instead of displaying an overwrite prompt
1019         when attempting to add files to already existing volumes;
1020
1021      b) console RAR "lt" command did not display seconds in file timestamp;
1022
1023      c) WinRAR failed to decompress .xxe files if they did not include
1024         "section N of xxencode" string in the body;
1025
1026      d) WinRAR could not restore contents of NTFS alternate data stream
1027         saved with -os switch if it was split between different volumes.
1028
1029
1030   Version 5.21
1031
1032   1. "Drag and drop context menu" options in "Settings/Integration/
1033      Context menu items" dialog allow to disable WinRAR archiving
1034      and extraction commands in context menu displayed after dragging
1035      and dropping files with right mouse button.
1036
1037   2. If winrar.ini file is present in the same folder as WinRAR installer,
1038      winrar.ini will be copied to WinRAR program folder after completing
1039      installation.
1040
1041   3. While previous versions could produce RAR5 volumes of slightly
1042      smaller than requested size sometimes, such situation is less
1043      likely now. In most cases volume size equals to specified by user.
1044
1045   4. Now by default WinRAR skips symbolic links with absolute paths
1046      in link target when extracting. You can enable creating such links
1047      with "Allow absolute paths in symbolic links" option on "Advanced"
1048      page of extraction dialog or with -ola command line switch.
1049
1050      Such links pointing to folders outside of extraction destination
1051      folder can present a security risk. Enable their extraction only
1052      if you are sure that archive contents is safe, such as your own backup.
1053      
1054   5. Bugs fixed:
1055
1056      a) WinRAR 5.20 issued unnecessary user account control (UAC) prompt,
1057         when running an executable from archive stored in UAC protected
1058         folder. Since nothing is extracted to folder containing an archive
1059         in such case, UAC prompt is not needed;
1060
1061      b) WinRAR could overwrite files with read-only attribute only
1062         when unpacking RAR and ZIP archive formats. Now it is also
1063         implemented for other archive formats supported by WinRAR;
1064
1065      c) "Elapsed time" and "Time left" were displayed incorrectly
1066         when applying "Convert" command to multiple archives
1067         and enabling "Add recovery record" option.
1068
1069   
1070   Version 5.20
1071
1072   1. If Windows User Account Control prevents extracting or archiving
1073      commands to create files in system protected folders, WinRAR attempts
1074      to start its another copy with administrator privileges to complete
1075      the operation. It is necessary to confirm privileges elevation
1076      in response to User Account Control prompt to allow such second
1077      WinRAR copy to run.
1078
1079   2. You can drag files in Explorer with right mouse button, drop them
1080      to some folder and select WinRAR archiving commands in context menu
1081      to create an archive with these files in the destination folder.
1082
1083   3. It is possible to use WinRAR.ini file instead of Registry to store
1084      WinRAR settings. You may prefer such approach if you plan to install
1085      WinRAR to removable media, such as USB flash drive, and then run it
1086      on different computers.
1087
1088      See "WinRAR.ini file" topic in "Configuration settings" chapter
1089      of WinRAR help for details.
1090
1091   4. Added extraction support for ZIP and ZIPX archives using 
1092      XZ compression algorithm.
1093
1094   5. If ZIP or ZIPX archive contains any compression algorithms except
1095      usual "Store" or "Deflate", algorithm names are displayed
1096      in "Version to extract" field of archive information dialog.
1097      Algorithms with names unknown to WinRAR will be assigned "m<num>"
1098      name, where "num" is a compression algorithm numeric identifier.
1099
1100   6. "Open with WinRAR" command is available in Windows context menus
1101      for archive formats supported by WinRAR. It can be turned off
1102      with "Open with WinRAR (for usual archives)" option in WinRAR
1103      "Settings/Integration/Context menu items..." dialog.
1104
1105   7. Command line RAR can read the default set of switches from rar.ini
1106      file stored in RAR program folder. Previously it was possible to
1107      define only the same set of switches for all RAR command with
1108      "switches=<switches>" string. Now rar.ini also allows to specify
1109      separate switch sets for individual RAR commands using
1110      the following syntax:
1111
1112      switches_<command>=<any RAR switches, separated by spaces>
1113
1114      For example:
1115
1116      switches_a=-m5 -s
1117      switches_x=-o+
1118
1119   8. Command "ch" supports switches -tl, -cu, -cl also for ZIP archives.
1120      Previously "ch" allowed these switches only for RAR archive format.
1121
1122   9. For archive formats lacking file time information, such as .bz2,
1123      .xz and .Z, WinRAR sets container archive modification time
1124      to extracted files. It does not apply to tar.bz2, tar.xz and tar.Z,
1125      which use file time stored in tar headers.
1126   
1127  10. "Keep broken files" extraction option is supported for bzip2 archives.
1128
1129  11. WinRAR icon in Windows context menus is scaled up correctly
1130      in high DPI screen modes such as 150% or 200% of normal text size.
1131
1132  12. It is possible to disable WinRAR "Benchmark" command with
1133      "Benchmark" variable of HKEY_CURRENT_USER\Software\WinRAR\Policy
1134      Registry key. In multi-user environment "Benchmark" command might
1135      abuse shared computational resources. See "Registry variables" topic
1136      in "Configuration settings" chapter of WinRAR help for more details.
1137
1138  13. Additionally to "sfxcmd" variable containing the entire command line,
1139      SFX module sets "sfxpar" variable containing command line parameters
1140      only, without leading SFX module name. These variables are set before
1141      starting a program specified in "Setup" command.
1142
1143  14. File overwrite prompt in console RAR displays the size and modification
1144      time for existing and new files.
1145
1146  15. When archiving from stdin with -si switch, RAR sets the current system
1147      time to modification time of archived file. Previous version did not
1148      set this time at all.
1149
1150  16. It is possible to use -si and -v<size> switches together. Previous
1151      versions did not allow to create volumes when archiving from stdin.
1152
1153  17. Warning is issued when starting unpacking 4 GB or larger file
1154      from RAR or ZIP archive to FAT32 patition, so user may cancel
1155      the operation. FAT32 does not support files of such size.
1156
1157      Also this warning is issued when starting to create RAR archive
1158      with "Store" (-m0) method if estimated archive size is 4 GB or more.
1159
1160  18. "Select all" button in "Settings/Integration" dialog is renamed to
1161      "Toggle all". Now it deselects archive formats if all they are
1162      already selected.
1163
1164  19. "Delete archive" extraction option correctly removes all .zip and .7z
1165      volumes. Previously it removed only the first volume in the set
1166      for these archive formats.
1167
1168
1169   Version 5.11
1170
1171   1. WinRAR can unpack TAR archives containing folders with pax
1172      extended headers. Previous versions failed to unpack them.
1173
1174   2. "Keep broken files" extraction option is supported for 7-Zip archives.
1175
1176   3. Bugs fixed:
1177
1178      a) WinRAR 5.10 did not set "hidden", "read-only" and "system"
1179         file attributes when unpacking ZIP archives;
1180
1181      b) WinRAR 5.10 failed to update self-extracting RAR archives
1182         containing nested ZIP archives stored without compression;
1183
1184      c) ZIP archive created with "Do not store paths" option
1185         included unnecessary empty name records for folders;
1186
1187      d) archived files could have 1 hour modification time error
1188         in Windows XP;
1189
1190      e) deleting a file in RAR5 solid archive containing files stored
1191         with -ver switch caused such files to lose version information;
1192
1193      f) black rectangles were displayed instead of toolbar buttons
1194         in 16- and 24- bit screen color modes and Windows custom text size
1195         larger than 100%.
1196
1197   
1198   Version 5.10
1199
1200   1. Added extraction support for ZIP and ZIPX archives using
1201      BZIP2, LZMA and PPMd compression.
1202
1203   2. Added extraction support for 7z split archives
1204      (.7z.001, .7z.002, ...).
1205
1206   3. Added support for AES-NI CPU instructions allowing to improve
1207      RAR encryption and decryption performance.
1208
1209   4. Default theme images are scaled up with better quality
1210      in high DPI display mode.
1211
1212   5. Environment variables, such as %temp%, can be used
1213      in "Files to add" field of archiving dialog.
1214
1215   6. Switch -ai can be used when creating RAR archive,
1216      so predefined values, typical for file and folder,
1217      are stored instead of actual attributes.
1218      Previously this switch could be used only when extracting.
1219
1220
1221   Version 5.01
1222
1223   1. RAR 5.0 archives can include an optional quick open information
1224      controlled with -qo[-|+] switch or "Quick open information" options
1225      group in archiving dialog. It allows to open the archive contents
1226      in WinRAR faster.
1227
1228      This version provides better update performance for archives
1229      containing both quick open information and service records,
1230      such as NTFS file security. Also default parameters of quick open
1231      information are optimized to achieve faster open time for such archives.
1232
1233   2. Bugs fixed:
1234
1235      a) "Find" command could fail when searching text string in .7z archives;
1236
1237      b) when opening RAR 5.0 archive with encrypted file names stored
1238         in another such archive, WinRAR could issue an erroneous message
1239         that password is incorrect. It happened only if passwords to inner
1240         and outer archives were different. It did not affect extraction,
1241         all files could be unpacked regardless of this message;
1242
1243      c) option "Use for all archives" in password dialog did not suppress
1244         additional password requests for RAR 5.0 archives with encrypted
1245         file names;
1246
1247      d) WinRAR address bar did not process correctly environment variable
1248         based paths, such as %temp%;
1249
1250      e) storing NTFS file security and alternate data streams did not work
1251         for file pathnames longer than 260 characters;
1252
1253      f) "Test" command could erroneously report damaged data in valid
1254         recovery record if only a part of files in RAR 5.0 archive
1255         was tested. It did not happen if entire archive contents was tested;
1256
1257      g) "Test" command erroneously reported errors when verifying
1258         RAR 4.x Unix symbolic links;
1259
1260      h) WinRAR "View" command did not work for files inside of BZIP2 archives;
1261
1262      i) if "High precision modification time" option in archiving dialog
1263         was turned off, WinRAR did not store the modification time at all
1264         instead of storing a lower precision time;
1265
1266      j) destination paths containing .\ or ..\ component did not work
1267         when extracting non-RAR archives in WinRAR command line mode;
1268
1269      k) WinRAR failed to unpack multivolume CAB archives.
1270
1271
1272   Version 5.00
1273
1274   1. New RAR 5.0 archiving format. You can use "RAR 5.0" option
1275      in archiving dialog or -ma command line switch to create
1276      RAR 5.0 archives.
1277      
1278      Older software including older WinRAR versions is not able to
1279      decompress RAR 5.0 archives, so if you plan to send an archive
1280      to other people, it is necessary to take the compatibility issue
1281      into consideration. You can select "RAR" instead of "RAR5" option
1282      in archiving dialog to create RAR 4.x archives compatible with
1283      previous WinRAR versions.
1284
1285   2. Changes in RAR 5.0 compression algorithm:
1286
1287      a) maximum compression dictionary size is increased up to 1 GB
1288         in 64 bit WinRAR. 32 bit WinRAR version can use up to 256 MB
1289         dictionary when creating an archive. Both 32 bit and 64 bit
1290         versions can unpack archives with any dictionary size,
1291         including 1 GB;
1292
1293      b) default dictionary size for RAR 5.0 is 32 MB, typically resulting
1294         in higher compression ratio and lower speed than RAR 4.x 4 MB.
1295         You can use "Dictionary size" archiving dialog option or -md<size>
1296         switch to change this value;
1297
1298      c) -md<size> switch syntax is modified to support larger dictionary
1299         sizes. Append 'k', 'm' and 'g' modifiers to specify the size
1300         in kilo-, mega- and gigabytes, like -md64m for 64 MB dictionary.
1301         If modifiers are not present, megabytes are assumed,
1302         so -md64m is equal to -md64;
1303
1304      d) RAR 5.0 format includes Intel IA-32 executable and delta
1305         compression algorithms, but RAR 4.x text, audio, true color
1306         and Itanium algorithms are not supported. These excluded algorithms
1307         are not efficient for modern data types and hardware configurations;
1308
1309      e) RAR 5.0 decompression can utilize several CPU cores.
1310         Though not to same extent as in compression algorithm,
1311         it improves the decompression speed on large files
1312         with poorly compressible data or when using BLAKE2 checksums.
1313
1314   3. Changes in RAR 5.0 archive format:
1315
1316      a) file times are stored as Coordinated Universal Time (UTC)
1317         instead of former local time, making file exchange among
1318         several time zones more straightforward;
1319
1320      b) file names and archive comments use UTF-8 encoding.
1321   
1322   4. RAR 5.0 recovery record is based on Reed-Solomon error correction
1323      codes. If recovery record size is large enough, 5% and more,
1324      the new error correction scheme provides much higher resistance to
1325      multiple damages comparing to RAR 4.x recovery record.
1326      Smaller record, such as 1 - 2%, or less random damage type would
1327      result in less difference between 4.x and 5.0. For single continuous
1328      damage 4.x and 5.0 efficiency is about the same.
1329
1330      Additionally to usual data erasures, the new recovery record
1331      is able to detect deletions and insertions of much larger size
1332      than in previous RAR versions. Maximum insertion size is several
1333      megabytes. Maximum deletion size depends on the damage type
1334      and in some cases can be as large as the recovery record size.
1335      
1336      Still, the best recovery performance and efficiency is achieved
1337      if no deletions and insertions are present, so all data including
1338      damaged sectors preserve their original positions. Thus, if you use
1339      some special software to copy an archive from damaged media,
1340      it is better to choose the mode, when damaged sectors are filled by
1341      zeroes or any other data instead of cutting them out completely
1342      from resulting file.
1343
1344      RAR 5.0 recovery record is more resistant to damage of recovery record
1345      itself and can utilize a partially corrupt recovery record data.
1346      Note, though, that "Repair" command does not fix broken blocks
1347      in recovery record. Only file data are corrected. After successful
1348      archive repair, you may need to create a new recovery record
1349      for saved files.
1350
1351      New recovery record is not based on 512 byte sectors anymore 
1352      and incorporates more complicated data structures. So it is impossible
1353      to specify its size in sectors. For RAR 5.0 archives the parameter of
1354      -rr[N] switch and rr[N] command is always treated as a percent of
1355      archive size regardless of presence of % character. Typically N%
1356      recovery record can repair up to N% of continuously damaged data
1357      and increases the archive size by only slightly more than N%.
1358      Ability to fix multiple damages is proportional to N.
1359
1360      We used "Screaming Fast Galois Field Arithmetic Using Intel
1361      SIMD Instructions" paper by James S. Plank, Kevin M. Greenan
1362      and Ethan L. Miller to improve Reed-Solomon coding performance.
1363      Also we are grateful to Artem Drobanov and Bulat Ziganshin
1364      for samples and ideas allowed to make Reed-Solomon coding
1365      more efficient.
1366
1367   5. "Test" command verifies validity of RAR 5.0 recovery record.
1368      Recovery record is tested after processing all archived files.
1369
1370      If corrupt archive contains the recovery record, it might be possible
1371      to repair it even if recovery record validity test is failed.
1372      "Repair" command attempts to utilize even a partially damaged
1373      recovery record. So treat the negative recovery record test result
1374      as a reason to re-create the archive if original files are still
1375      available, but not as a reason to avoid "Repair" command.
1376
1377   6. Changes in RAR 5.0 encryption algorithm:
1378
1379      a) encryption algorithm is changed from AES-128 to AES-256 in CBC mode.
1380         Key derivation function is based on PBKDF2 using HMAC-SHA256;
1381
1382      b) special password verification value allows to detect most of
1383         wrong passwords without necessity to unpack the entire file;
1384
1385      c) if archive headers are not encrypted ("Encrypt file names" option
1386         is off), file checksums for encrypted RAR 5.0 files are modified
1387         using a special password dependent algorithm, to make impossible
1388         guessing file contents based on checksums. Do not expect such
1389         encrypted file checksums to match usual CRC32 and BLAKE2 values.
1390   
1391   7. RAR 5.0 archives allow to utilize 256 bit length BLAKE2sp hash
1392      ( https://blake2.net ) instead of 32 bit CRC32 as a file checksum.
1393      Enable "Use BLAKE2 file checksum" option in "Options" page of
1394      archiving dialog or specify -htb command line switch to use BLAKE2
1395      checksums.
1396
1397      While producing slightly larger archives, BLAKE2 can be used
1398      for file contents identification. If two files have the same
1399      BLAKE2 value, it practically guarantees that file contents
1400      is the same. BLAKE2 error detection property is also stronger
1401      than in much shorter CRC32.
1402
1403   8. Features removed:
1404
1405      a) authenticity verification feature did not provide the required
1406         level of reliability and was removed;
1407      
1408      b) switch -en (do not add "end of archive" block) is not supported
1409         by RAR 5.0 archives, which always have the end of archive block.
1410         This block helps WinRAR to safely skip external data like
1411         digital signatures appended to archive;
1412
1413      c) old style extension based arcname.rNN volume names are not
1414         supported by RAR 5.0 archives, which use only arcname.partN.rar
1415         volume names;
1416      
1417      d) file comments are not supported anymore both in RAR 4.x
1418         and RAR 5.0 archives. Console RAR 'cf' command is removed.
1419         It does not affect the archive comment support, which is present
1420         in both versions of archive format and is not planned for removal.
1421
1422   9. "Set password" command and "Dictionary size" option are moved to
1423      "General" page of archiving dialog.
1424   
1425  10. You can use "Save symbolic links as links" option on "Advanced" page
1426      of archiving dialog to save and restore NTFS symbolic links
1427      and reparse points as links, so their contents is not archived.
1428      Command line equivalent of this option is -ol switch.
1429
1430      Similar option for NTFS hard links is "Save hard links as links".
1431      Its command line equivalent is -oh switch.
1432
1433      Both options are available only for RAR 5.0 archive format.
1434   
1435  11. Added extraction only support for XZ archive format.
1436   
1437  12. Changes in recovery volume processing in RAR 5.0 archive format:
1438
1439      a) maximum number of RAR+REV volumes in RAR 5.0 format is 65535
1440         instead of 255;
1441
1442      b) recovery volume operations are faster than in RAR 4.x;
1443
1444      c) additionally to recovery data, RAR 5.0 REV files also store
1445         service information such as checksums of protected RAR files.
1446         So they are slightly larger than RAR volumes which they protect.
1447         If you plan to copy individual RAR and REV files to some removable
1448         media, you need to take it into account and specify RAR volume
1449         size by a few kilobytes smaller than media size.
1450  
1451  13. Maximum path length for files in RAR and ZIP archives is increased
1452      up to 2048 characters.
1453  
1454  14. Command line RAR returns the exit code 11 if it can detect that
1455      user entered a wrong password. This code can be returned only
1456      for RAR 5.0 archives. It is impossible to distinguish a wrong
1457      password and data damage for RAR 4.x archives.
1458
1459  15. 'v' and 'l' commands display archived file names in the end of line,
1460      not in that beginning as before. Also some fields previously
1461      available in 'l' and 'v' output are now shown only by 'lt' and 'vt'.
1462      
1463      'vt' and 'lt' commands provide the detailed multiline information
1464      for every archived file.
1465
1466      'vta' and 'lta' also include service headers into list.
1467
1468   16. Now the default charset for filelists in commands like
1469       'rar a arcname @filelist' is ANSI for both WinRAR and console RAR.
1470       In previous versions it was ANSI for WinRAR and OEM for console RAR.
1471       You can use -sc<charset>l switch to override this default.
1472
1473   17. Internal WinRAR viewer can detect and display files in UTF-8
1474       and UTF-16 little endian encodings.
1475
1476   18. UTF-16 little endian encoding is used in RAR and WinRAR log file
1477       rar.log, so Unicode file names are stored in the log correctly.
1478       WinRAR automatically truncates the old rar.log file in non-Unicode
1479       format to avoid mixing different encoding in the same log file.
1480       In case of console RAR you need to delete the old rar.log manually,
1481       otherwide RAR will append UTF-16 messages to existing rar.log.
1482
1483       You can use -sc<charset>g switch to change the default log file
1484       encoding, such as -scag for ANSI encoding.
1485
1486   19. Command line 'r' (repair) command can include an optional destpath\
1487       parameter defining the destination folder for repaired archive:
1488
1489       rar r archive.rar destpath\
1490      
1491   
1492   Version 4.20
1493
1494   1. Changes in RAR compression:
1495
1496      a) RAR general compression algorithm is optimized for better
1497         utilization of several processor cores. While some speed gain
1498         is possible even in single processor mode, best results
1499         are achieved in multi-core environment.
1500
1501         Speed gain depends on data type and average file size.
1502         Several cores are utilized more efficiently when compressing
1503         large files.
1504
1505      b) we had to increase memory requirements to achieve higher
1506         compression speed. General RAR compression algorithm allocates
1507         about 120 MB comparing to 40 MB in WinRAR 4.11;
1508
1509      c) RAR text compression algorithm cannot utilize several CPU cores
1510         efficiently, so its performance in multiprocessor environment
1511         is much lower than for general algorithm. Also its decompression
1512         speed is much lower than in general algorithm regardless of
1513         CPU number. So we decided to disable the text algorithm by default.
1514
1515         If you need maximum possible compression ratio for plain text data
1516         regardless of speed, you can enable the text compression
1517         in "Advanced compression parameter" dialog. Press "Compression..."
1518         button on "Advanced" page of archiving dialog to access it.
1519         You can also change this option permanently in default compression
1520         profile;
1521
1522         In the command line mode the text compression can be enabled
1523         with -mct switch;
1524
1525      d) "Fastest" (-m1) compression mode also supports several processor
1526         cores now. In 4.11 it could use only a single processor core.
1527
1528   2. RAR general decompression algorithm speed is slightly improved,
1529      though not to same extent as RAR compression. RAR decompression
1530      is not able to use several processor cores, so its performance
1531      does not depend on a number of cores.
1532
1533   3. Changes in ZIP compression:
1534
1535      a) now ZIP compression supports several processor cores resulting
1536         in noticeably higher performance in multi-core environment.
1537         Single CPU ZIP compression is also faster than in 4.11;
1538
1539      b) memory use for ZIP compression is increased to about 15 MB.
1540
1541   4. Recovery volume creating and processing can use several CPU cores
1542      resulting in higher speed. Though, typically hard drive seek speed
1543      is a limiting factor for recovery volumes, so this gain is most
1544      noticeable when working with solid state drive.
1545
1546   5. Now the allowed <threads> value for -mt<threads> switch is 1 - 32,
1547      not 0 - 16 as before.
1548
1549   6. "Find files" command can search data in 7-Zip archives.
1550      Previously "Find files" did not support .7z archive format.
1551
1552   7. Windows 2000 is not supported by WinRAR and WinRAR self-extracting
1553      modules anymore.
1554
1555   8. "Save current settings" button in "Advanced SFX options" dialog
1556      is now available only when converting an existing archive to SFX.
1557      Options saved with this button are applied only to convert to SFX
1558      operation.
1559
1560      If you create or update SFX archive, only SFX options stored
1561      in default compression profile are used. Options saved
1562      in "Advanced SFX options" dialog are ignored for these operations.
1563
1564
1565   Version 4.11
1566
1567   1. Bugs fixed:
1568
1569      a) WinRAR did not store NTFS "Compressed" attribute, when creating
1570         RAR archives;
1571
1572      b) WinRAR crashed in command line mode if @filelist parameter 
1573         was present and 'filelist' did not exist. This bug affected
1574         only WinRAR.exe, not RAR.exe;
1575
1576      c) if -x*\somefolder\* exclusion mask was specified when archiving 
1577         and if name of current folder contained 'somefolder', 
1578         WinRAR excluded all files and stopped creating an archive;
1579
1580      d) GUI self-extracting archives did not work in Windows
1581         Preinstallation Environment (Windows PE).
1582
1583   
1584   Version 4.10
1585
1586   1. WinRAR can create ZIP archives of practically any size.
1587
1588      2 GB archive size and 65535 file number ZIP limitations of previous
1589      WinRAR versions are not valid anymore.
1590
1591   2. WinRAR can create multivolume ZIP archives, which are also known as
1592      split ZIP files.
1593
1594      ZIP volumes have names like 'volname.zip', 'volname.z01', 'volname.z02'.
1595      Use a volume with ".zip" file extension in all archive processing
1596      operations like starting extraction or opening an archive.
1597
1598      Unlike RAR volumes, ZIP volumes cannot be self-extracting.
1599
1600      WinRAR needs to have access to all ZIP volumes of multivolume file set
1601      at the same time, when creating or unpacking them. So it is impossible
1602      to create or unpack ZIP volumes on removable disks, one volume
1603      per disk. You need to create them all in the same folder.
1604
1605   3. Added the high precision file time support in ZIP archives.
1606      WinRAR can store and extract modification, creation and last access
1607      file time in ZIP archives with 100 nanosecond precision.
1608
1609      You need to set "High precision modification time" option in "Time"
1610      part of archiving dialog to store all 3 times in archive.
1611      Set appropriate "File time" options in "Advanced" part of extraction
1612      dialog to choose times to extract.
1613
1614   4. Added support for Unicode names stored in ZIP extra field data.
1615      Different ZIP tools store Unicode names either in file header
1616      or in ZIP extra field and now WinRAR can correctly process both types
1617      of Unicode names.
1618
1619   5. "Synchronize archive contents" option and -as command line switch are
1620      supported in ZIP format.
1621
1622   6. Modifications of switch -ag behavior:
1623
1624      a) -ag can be used with all RAR and WinRAR commands, not just
1625         with archiving only;
1626
1627      b) 'N' format character behavior differs in archiving and non-archiving
1628         operations. When archiving, it is incremented until the first unused
1629         name is found. In non-archiving operations like extracting it selects
1630         the existing archive preceding the first unused name;
1631
1632      c) 'I' format character allows to specify minutes regardless of presence
1633         and position of 'H' (hours) in format string. It can be used
1634         instead of 'M' (minutes), when you wish to place minutes before hours
1635         or do not need hours at all.
1636
1637   7. By default, WinRAR proposes to update an archive if viewer modified
1638      an opened file or created any new files. New "Ignore modifications for"
1639      option in "Settings/Viewer" dialog allows to disable such behavior.
1640      You can enter one or several file masks separated by spaces here
1641      and WinRAR will not prompt to update an archive if file created
1642      or modified by viewer matches one of these masks.
1643
1644   8. Changes in volume size input field. Now you can select size units
1645      in the drop down list to the right of volume size. Previous way
1646      to define size modifiers, by entering 'k', 'm', etc. character
1647      after the numeric size value, is also supported.
1648
1649   9. Changes in "Predefined sizes" in "Define volume sizes" dialog.
1650      Floppies and ZIP disks are replaced by 5 MB and 100 MB volumes,
1651      added new entries for maximum FAT32 file size and for Blu-ray disks.
1652
1653  10. New "Wipe files if password is set" option in "Options" page of
1654      archiving dialog. If you prefer to always delete encrypted files
1655      securely, you can enable "Wipe files if password is set"
1656      in the default compression profile.
1657
1658  11. New "Wipe temporary files/Encrypted only" option in "Settings/Security".
1659      It allows to use a slower and more secure delete for temporary files
1660      extracted from archives identified by WinRAR as encrypted.
1661      Quick delete is used for all other temporary files.
1662
1663  12. Changes in "Convert archives" command:
1664
1665      a) now it is possible to convert encrypted archives. Previously
1666         "Convert archives" command skipped them.
1667
1668         Though, if you still prefer to skip them, you can do it
1669         by enabling "Skip encrypted archives" option in "Convert archives"
1670         dialog. It might be useful if you wish to run the conversion
1671         command in unattended mode, avoiding password prompts;
1672
1673      b) special "rar2" archive type, which was specific for RAR 1.x
1674         and 2.x archives, is removed. Now "rar" archive type controls
1675         conversion of all versions of RAR archives.
1676
1677         Since the convert command does not need to detect RAR archive
1678         version anymore, the initial search for archives is performed
1679         faster, resulting in shorter delay before displaying
1680         "Convert archives" dialog.
1681
1682  13. New -log[fmt][=name] switch allows to write archive and file names
1683      to log file in archiving command for RAR and ZIP formats and also
1684      in extracting, deleting and listing commands for RAR format.
1685
1686      This switch is especially useful, when you need to further process
1687      an archive created with -ag or -v switches, because -log provides
1688      the archive name generated by WinRAR.
1689
1690  14. New -@[+] switch allows to process all parameters starting from
1691      '@' character either as file names (-@) or as file lists (-@+).
1692
1693  15. "Setup program" SFX options are moved from "General" to "Setup" page
1694      of "Advanced SFX options" dialog. Both "Run after extraction"
1695      and "Run before extraction" are now multiline, so it is possible
1696      to specify several setup programs for same SFX archive.
1697
1698  16. "SetupCode" SFX script command instructs SFX archive to wait
1699      for termination of setup program and return the exit code of
1700      setup program increased by 1000 as the exit code of SFX executable.
1701
1702      GUI equivalent of this command is "Wait and return exit code" option
1703      on "Setup" page of "Advanced SFX options" dialog.
1704
1705  17. SFX does not support "S" (create in the top level of Start Menu)
1706      "Shortcut" command mode anymore. Recent Windows versions do not allow
1707      programs to add items to the top of Start Menu.
1708
1709  18. Volume size in archiving and wizard dialogs can be specified as
1710      a decimal fraction. Decimal mark is defined by Windows regional
1711      settings.
1712
1713      -v<size> command line switch also allows decimal fractions.
1714      In command line mode the dot (.) is always used as the decimal mark.
1715      For example, -v1.5g switch means 1.5 gigabytes.

1717
1718   Version 4.01
1719
1720   1. Added support for file sizes stored in binary format in TAR archives.
1721      Some TAR archives use the binary size format instead of octal
1722      for files larger than 8 GB.
1723   
1724   2. Bugs fixed:
1725
1726      a) "Repair" command failed to properly reconstruct structure
1727         of RAR archives, which contained at least one file with packed
1728         size exceeding 4 GB.
1729
1730         This bug did not affect the recovery record based repair.
1731         It happened only if recovery record was not found and WinRAR
1732         performed reconstruction of archive structure;
1733
1734      b) even if "Do not extract paths" option in "Advanced" part of
1735         extraction dialog was set as the default, WinRAR still unpacked
1736         file paths if called from Explorer context menu;
1737
1738      c) after entering a wrong password for encrypted ZIP archive,
1739         sometimes WinRAR ignored subsequent attempts to enter a valid
1740         password;
1741
1742      d) "Wizard" command did not allow to create self-extracting 
1743         and multivolume archives, when compressing a single folder
1744         or a file without extension;
1745
1746      e) "Import settings from file" command did not restore multiline
1747         comments in WinRAR compression profiles;
1748
1749      f) when converting RAR volumes having name1.name2.part#.rar name format,
1750         "Convert archives" command erroneously removed ".name2" name part.
1751         So resulting archive had name1.rar file name instead of expected
1752         name1.name2.rar;
1753
1754      g) RAR could crash when creating a new archive with -agNNN switch
1755         if archive number in generated name was 110 or larger;
1756
1757      h) WinRAR failed to display non-English file names in 7-Zip archives
1758         properly if they used a non-default code page. It was the display
1759         only problem, such names were unpacked correctly.
1760
1761
1762   Version 4.00
1763
1764   1. RAR decompression speed is improved. Depending on data type,
1765      decompression can be up to 30% faster than in previous versions.
1766
1767      Both the general RAR algorithm and most of special RAR multimedia
1768      methods benefit from this improvement. The only module of RAR
1769      algorithm, which is not affected, is "Text compression" method.
1770
1771   2. Changes in ISO support:
1772
1773      a) UDF support is upgraded to UDF 2.50 revision. It makes possible
1774         to unpack most of Blu-ray ISO files;
1775
1776      b) when browsing UDF ISO file, UDF revision number is displayed
1777         after the "UDF" format name in WinRAR address bar
1778         and in archive information dialog;
1779
1780      c) WinRAR sets the folder modification date when unpacking folders
1781         stored in UDF and ISO9660 files.
1782   
1783   3. Changes in password dialog:
1784
1785      a) WinRAR uses the same format of password dialog both when archiving
1786         and extracting, so "Show password" option is available also
1787         when extracting;
1788
1789      b) "Organize passwords..." button in password dialog provides
1790         access to password organizer interface, where you can specify
1791         your frequently used passwords. You will be able to access these
1792         saved passwords using the drop down list or autocomplete feature
1793         in password dialog.
1794
1795         It is important to know that saved passwords are not encrypted
1796         and anybody having access to your computer can view them.
1797         Use "Organize passwords" feature only if your computer is
1798         protected from unauthorized access;
1799
1800      c) "Use for all archives" option is available in password dialog
1801         when unpacking several archives at once. You can utilize it
1802         to apply an entered password to all archives.
1803
1804         If you use this option with an empty password, WinRAR will skip
1805         all encrypted archives;
1806
1807      d) Unlike previous versions, the password from default compression
1808         profile is not used for extraction.
1809         
1810         If you wish to use the same password for all extracting archives,
1811         press "Organize passwords..." button in the password dialog
1812         and define a new password entry, specifying "*" file mask 
1813         in "Select for archives" field.
1814   
1815   4. In Windows 7 WinRAR will display the total operation progress
1816      also on WinRAR icon on Windows taskbar. You can disable it using
1817      "Taskbar progress bar" option on "General" page of WinRAR settings.
1818
1819   5. Numerous Unicode support improvements allow to process non-English
1820      file names more smoothly. These improvements include:
1821
1822      a) better Unicode handling in WinRAR in "Rename", "Convert",
1823         "Find" and other commands, in folder tree panel, in password 
1824         request dialog and in many other parts of WinRAR interface;
1825
1826      b) correctly displayed Unicode names in WinRAR items in Explorer
1827         context menus;
1828
1829      c) Unicode support in .lng files, making WinRAR localization
1830         possible for Unicode only languages.
1831   
1832   6. Changes in -x<file> switch syntax. Now you can specify a wildcard
1833      exclusion mask for folders. Such mask must have the trailing '\'
1834      character, like -x*tmp*\ or -x*\temp\
1835
1836   7. New "Extract relative paths" option in "Advanced" part of extraction
1837      dialog. If you browse some archive subfolder in WinRAR shell
1838      and enable "Extract relative paths" option, the path part up to
1839      and including the current subfolder will be removed from extracted
1840      file paths.
1841      
1842      For example, if you are inside of "Backup\MyData" archive folder
1843      and extract "Images" folder, it will be extracted as "Images",
1844      not as "Backup\MyData\Images".
1845
1846      This option is the new default extraction mode, but you can change
1847      the default back to WinRAR 3.x style. Just select "Extract full paths"
1848      and then press "Save settings" in "General" part of extraction dialog.
1849   
1850   8. Windows 98, Windows Me and Windows NT are not supported by WinRAR
1851      and WinRAR self-extracting modules anymore. Minimum Windows version
1852      required for WinRAR 4.0 is Windows 2000.
1853      
1854      If you need to run WinRAR on older Windows, you can download
1855      previous WinRAR versions from ftp://ftp.rarlab.com/rar
1856
1857   9. If TAR, TAR.GZ or TAR.BZ2 archive contains symbolic or hard links
1858      and if destination file system is NTFS, WinRAR will create these
1859      links when unpacking such archive. WinRAR will create symbolic links
1860      as symbolic and hard links as hard in Windows Vista and newer
1861      and it will create all links as hard in older Windows.
1862
1863      If destination file system is FAT32 or any other not supporting
1864      file links, WinRAR will skip links when unpacking TAR, TAR.GZ
1865      and TAR.BZ2 archives.
1866   
1867  10. Recovery volume processing involves less disk seek operations
1868      resulting in higher performance.
1869
1870  11. You can select Windows 7 library in tree panel in extraction dialog
1871      and WinRAR will use its default save location as the destination path.
1872
1873  12. "Report" command allows to select HTML, Unicode text and usual text
1874      as output format for report file. Unlike previous WinRAR versions,
1875      now WinRAR preservers Unicode characters in reports when using HTML
1876      or Unicode text format. So non-English characters in file names
1877      will be displayed properly in such reports.
1878   
1879  13. Message list in GUI SFX archives displays only operation status
1880      and error messages. It does not contain names of all extracted files
1881      anymore. This change improves the speed and reduces memory requirements
1882      for SFX archives containing a large number of files. Also it makes
1883      easier to locate error messages, because they are not hidden among
1884      extracted file names.
1885
1886  14. GUI SFX archives display "Extract" button instead of "Install"
1887      if no "Setup" or "Presetup" commands are present in the archive
1888      comment. If you prefer "Install" button, but do not need to
1889      execute any setup programs, you can add "Setup=<>" command.
1890  
1891  15. WinRAR displays the current percent above the operation progress bar
1892      when repairing an archive containing the recovery record
1893      and when processing recovery volumes.
1894
1895  16. WinRAR limits the maximum possible volume size to 4 GB minus 1 byte
1896      when creating RAR volumes on a disk with FAT or FAT32 file system
1897      in volume size autodetecting mode. These file systems do not support
1898      4 GB and larger files.
1899
1900  17. If "Wait if other WinRAR copies are active" option is enabled
1901      and WinRAR waits for another copy, you can press "Continue" button
1902      in command progress window to force WinRAR to stop waiting.
1903      So now "Continue" button allows to override the state of
1904      "Wait if other WinRAR copies are active" option for current operation.
1905
1906  18. WinRAR displays one password request instead of two, when saving
1907      an encrypted file back to RAR or ZIP archive after modifying it
1908      in some external editor. Previous WinRAR versions usually requested
1909      the password twice, both when extracting the original file
1910      and archiving its modified copy. Only RAR archives with encrypted
1911      file names were processed with the single password prompt.
1912
1913  19. New error code 10 ("no files") is added to list of error codes
1914      returned in command line mode by RAR and WinRAR. This new code
1915      can be returned by archive, extract, delete and repair commands.
1916      It means that RAR did not find any files matched the specified
1917      file or archive mask.
1918  
1919  20. File name area in file overwrite dialog occupies several lines now.
1920      It makes possible to display much longer names.
1921  
1922  21. Now switch -ep3 converts not only disk letters, but also UNC paths.
1923      So \\server\share will be converted to __server\share when archiving
1924      and restored to the original \\server\share when extracting with -ep3.
1925
1926  22. New "Background extraction" option in "Advanced" part of extraction
1927      dialog places WinRAR into background, when extracting files.
1928      You can save its default state with "Save settings" button in "General"
1929      part of extraction dialog, just like for other extraction options.
1930
1931      "Background archiving" option from the default compression profile
1932      does not affect the extraction behavior anymore.
1933
1934  23. "Mode..." button in operation progress window is enabled also
1935      when extracting or testing archives. It provides access to 
1936      "Command parameters" dialog, where you can set "Turn PC off when done"
1937      option for extraction and test operations.
1938
1939      Previously this dialog was accessible only when archiving.
1940
1941  24. Bugs fixed:
1942
1943      a) renaming a file in archive could also rename all other files
1944         with the same name in other folders of the same archive;
1945
1946      b) previous versions displayed the wrong total packed size
1947         in "Info" command for multivolume CAB archives;
1948
1949      c) in ZIP archives 'U' (update) and 'F' (fresh) commands could
1950         erroneously update even files not specified in the command line.
1951         It happened only for files in current folder which names matched
1952         files in ZIP archive. This bug was not present in usual 'A' (add)
1953         archiving mode.
