7-Zip 16.04 Final:
– The bug was fixed: 7-Zip 16.03 exe installer under Vista didn’t create
links in Start / Programs menu.
– Some bugs were fixed in RAR code.
7-Zip 17.01 Beta:
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.
The BUGs were fixed:
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.
