7zip v18 ist erschienen - auch sicherheitsrelevant

https://sourceforge.net/p/sevenzip/discussion/45797/thread/c89dff27/
listet Neuheiten:
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.

PS: hat jemand einen besseren Rubrikenvorschlag hierfür?
