although the feature still calling as "experimental", but zstd uses this in its own client since v.1.4 IIRC and the only known drawback would be significant regress of compression ration if guess considerably underestimates, but it does no matter in case of known file size.
- allow to specify brotli window size
- parameter -m0=brotli:long=n, BROTLI_MAX_WINDOW_BITS (24) used by default in brotli-mt, smaller == faster
- note that :long can be set up to BROTLI_LARGE_MAX_WINDOW_BITS (30), whereas :wlog can be set up to BROTLI_MAX_WINDOW_BITS (24) only...
- todo: check whether set of BROTLI_PARAM_LARGE_WINDOW to BROTLI_TRUE is needed if (lgwin > BROTLI_MAX_WINDOW_BITS)
- implementation of single-threaded brotli compression / decompression for .br data

- 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.
- add the "fast compression levels" of zstd via "fast" option (fast=1..64)
- change the 7-Zip property sizes of LZ4, LZ5 and Zstandard to 3
- 3 and 5 byte header are valid now (default is 3)
- update the Methods-Extern.md file, to reflect the property changes
- add some pragma definitions to brotli port.h
- change lz4 code, to include zstd/xxhash.h
- fix various objects in makefile's
- fix LzHandler.cpp, LZIP has now 0xC5 @ Guid.txt
- improve logging on AppVeyor
- fix version numbers in codecs
- rename "Codec_zstdF" to "Codec_zstd_legacy"
- add missing objects for lizard
- 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.
- 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
- 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
- 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
