- 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.
