- 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.
- ZIP unpacking code was improved.
- 7-Zip now can unpack OBJ/COFF files.
- 7-Zip now can unpack DMG archives that use LZFSE compression method.
- 7-Zip now doesn't allow update operation for archives that have read-only attribute.
- 7-Zip command line: @listfile now doesn't work after -- switch.
Use -i@listfile before -- switch instead. - new -sse switch to stop archive creating, if 7-Zip can't open some input file.
- 7-Zip now reserves file space before writing to file (for extraction from archive).
It can reduce file fragmentation. - Internal changes in code.
- The BUGs were fixed:
7-Zip could add unrequired alternate file streams to WIM archives,
for commands that contain filename wildcards and -sns switch.
Extracting from tar with -si switch didn't set timestamps for directories. - Some bugs were fixed. 7-Zip could crash in some cases.
