1. Performance improvements when deleting files in solid RAR archives:

     a) if there are no non-zero files after deleted files, archive
        recompressing isn't performed;
     
     b) part of archive before deleted files is copied as is, without
        repacking. Its contents is unpacked to memory if necessary,
        but not recompressed;

     c) semi-solid archive processing involves only solid blocks containing
        deleted files. Unaffected solid blocks are copied as is.
  
  2. "Generate archive name by mask" archiving option and -ag command line
      switch:

     a) new 'K' format character defines the current day of week 
        name as a text string;

     b) new 'O' format character defines the current month name as a text
        string regardless of format character number. Unlike "MMM" mask,
        it allows to use shorter or longer than 3 character names,
        such as -agOO;

     c) excessive format characters exceeding the available field width
        are now ignored instead of appending to archive name.
        So it is possible to use full month or week day names by providing
        format characters in the amount equal or exceeding the longest name,
        such as -agKKKKKKKKKK for day of week names.
  
  3. Command line -s switch:
  
     a) switch -s accepts the optional parameter preceded by '=' character.
        
        Switches -s, -se, -sv, -sv-, -s- are replaced by -s=f, -s=e,
        -s=v, -s=d, -s=-. Previous versions of these switches are still
        supported in the current version, but can be removed in the future.

        It is allowed to combine multiple modifiers in the same switch,
        such as -s=e100f.

     b) new switch -s=r resets the solid statistics before adding new files
        to existing archive.
  
  4. Switch -tk now accepts the optional date parameter in YYYYMMDDHHMMSS
     format. If used without parameter when modifying an archive,
     it preserves the original archive time. If optional parameter
     is present, it is assigned to archive modification time.

     It is allowed to insert separators like '-' or ':' to the date string
     and omit trailing fields. For example, switch -tk2025-06-01 is correct.

  5. "Specified time" is added to "Set archive time to" options on "Time"
     page of archiving dialog. It allows to assign the manually entered time
     to newly created or modified archives.
  
  6. UTF-8 output format and byte order mask options are added to
     "Generate report" command.
  
  7. "Cloud files" option is added to "Where to check for SFX archives"
     group in "Settings/Integration/Context menu items..." dialog.

     If this option is off, WinRAR shell extension will not attempt
     to detect if archive is self-extracting, when right clicking
     an executable cloud file not available locally. This detection
     involves data read and can be slow for such files.

     This option relies on file attributes returned by a cloud storage
     provider and can be ignored if required attribute isn't supported
     by specific cloud service.

  8. "Copy to clipboard" button at the bottom of "Search results" dialog
     places current results of "Find files" command to clipboard.

  9. It takes less time to open a large archive with a lot of files
     and folders in WinRAR file list. This is most noticeable for ZIP
     archives containing millions of files.

 10. Improved extraction speed of TAR and TAR based archives,
     such as .tar.gz or tar.xz. It is most visible for hard disk drives
     with slower seek time and large archives containing a lot of files.

 11. SFX module sets sfxnamenoext environment variable, containing
     SFX archive name without path and extension. It allows to append
     the archive name to user defined destination path like:

     Path=c:Util%sfxnamenoext%"

 12. "minsize" parameter, defining the minimum file reference size
     in -oi[0-4][:] switch, now can include an optional trailing
     unit size character. So -oi:1m is the equivalent of -oi:1048576.

 13. Switch -x recognizes exclude paths with both Windows and Unix style
     path separators, so -xfolderfile and -xfolder/file do the same.
     Previously only -xfolderfile excluded the file.

 14. Bugs fixed:

     a) "Files to exclude" field of archiving dialog was ignored for all
        but first ZIP archives if "Put each file to separate archive"
        option was turned on;

     b) when processing "Convert archives" command, "Use for all archives"
        option in the password prompt was available only for encrypted
        archives with file name encryption and couldn't be enabled
        when converting archives without encrypted file names
