- by default, 7-Zip ZS creates lz4 streams with skippable frames, cause this
makes parallel decompression possible
- but: sometimes this feature is not needed or wanted
- this patch will skip the writing of the additional frames for lz4, when
compressing single threaded (-mmt=1)
- 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.
- 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
