- The performance of LZX compression in its default settings has been
- improved by a further 5-10%.
-
- The default compression mode for wimcapture is now LZX compression in
- its default mode, which is the same as '--compress=maximum'.
-
- You can now specify an optional integer compression level to the
- '--compress' or '--solid-compress' options; e.g. '--compress=lzx:75'.
- Currently, the default level in all cases is 50. This capability
- deprecates the '--compress-slow' (or '--recompress-slow') option to
- several wimlib-imagex commands.
-
- The '--pack-streams', '--pack-compress', and '--pack-chunk-size' options
- to several wimlib-imagex commands have been deprecated in favor of more
- "standard" names: '--solid', '--solid-compress', and
- '--solid-chunk-size', respectively.
-
- Added 'verify' subcommand to 'wimlib-imagex'.
-
- The XPRESS compressor no longer supports chunks larger than 65536 bytes.
- There is little point in having larger chunks, since the LZ77 sliding
- window for XPRESS cannot be larger than 65536 bytes. This change does
- not affect the default XPRESS chunk size, which is 32768.
-
- The new (as of v1.7.0) extraction code will no longer run out of file
- handles when extracting many (1000+) identical files.
