- Encryption strength for 7z archives was increased the size of random
initialization vector was increased from 64-bit to 128-bit, and the
pseudo-random number generator was improved.
- Some bugs were fixed.
- Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.
7-Zip now uses additional memory buffers for multi-block LZMA2 compression.
CPU utilization was slightly improved.
- 7-zip now creates multi-block xz archives by default. Block size can be
specified with -ms[Size]{m|g} switch.
- xz decoder now can unpack random block from multi-block xz archives. 7-Zip
File Manager now can open nested multi-block xz archives (for example,
image.iso.xz) without full unpacking of xz archive.
- 7-Zip now can create zip archives from stdin to stdout.
- 7-Zip command line: @listfile now doesn't work after -- switch. Use
-i@listfile before -- switch instead.
fixed bugs:
- 7-Zip could add unrequired alternate file streams to WIM archives, for
commands that contain filename wildcards and -sns switch.
- 7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.
- 7-Zip 17.00 beta ignored "Use large memory pages" option.
- pool.c, zstdmt_compress.c and some more header files are needed now
- improved manifest files for 7-zip.dll, 7zG.exe and 7zFM.exe
- update README and version numbers for release 1.3.0 R1
- changed to real Lizard code v1.0 (I used LZ5 v2.0)
- add Lizard file handling, so '.liz' files can be used in windows
- changed CompressDialog (Lizard has 4 entries in the methods now)
- added Lizard icon
- corrected copyright information in new codecs
- fixed thread combobox for the new codecs

- update of zstd-mt library
- add brotli v0.6.0
- add lizard v2.0
- xxhash is from zstd for lz4, lz5 and lizard now
- update also the documentation, where needed
- the standard 7-Zip will always use LZMA2 Level 5
- my version used always: ZStandard Level 3
- but now, it uses: the registry settings from the last CompressDialog
- you can open / crate .tar.zst files now
- direct compressing of files with zstd works also
- you can also open files compressed with pzstd
- next version will do also threaded compression like pzstd does
- zst files can be registred with 7-Zip ZS now
- update to latest zstd dev release v1.0.1
- the About Box will give you a hint, that this 7-Zip is not the default one
- update to 0.7.3
- GUI improvements:
- ZStandard Version and Level is shown in FileManager
- method and level selection is better
- this 7-Zip Version defaults to ZSandard now
