7-Zip 20.00 Alpha
7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5, that can work faster than bt4 and hc4 match finders for the data with big redundancy.
The compression ratio was improved for Fast and Fastest compression levels with the following default settings:
Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.
Fast level (-mx3) : hc5 match finder with 4 MB dictionary.
Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra compression levels.
bzip2 decoding code was updated to support bzip2 archives, created by lbzip2 program.
Some bugs were fixed.
New localization: Turkmen.

v 20.01 alpha 2020-08-06
-------------------------
- The default number of LZMA2 chunks per solid block in 7z archive was increased to 64.
It allows to increase the compression speed for big 7z archives, if there is a big number
of CPU cores and threads.
- The speed of PPMd compressing/decompressing was increased for 7z/ZIP/RAR archives.
- The new -ssp switch. If the switch -ssp is specified, 7-Zip doesn't allow the system
to modify "Last Access Time" property of source files for archiving and hashing operations.
- Some bugs were fixed.
- New localization: Swahili.

"7zip ZS" - aktuell gehaltener Abkömmling mit zusätzlichen Pack-Algorithmen (Codecs): https://github.com/mcmilk/7-Zip-zstd

Für mich interessant wegen der Zstandard Unterstützung (die auch in Peazip enthalten wäre - aber irgendwie bin ich an 7zip gewöhnt).

v 21.04 beta 2021-11-02
-------------------------
- 7-Zip now reduces the number of working CPU threads for compression,
if RAM size is not enough for compression with big LZMA2 dictionary.
- 7-Zip now can create and check "file.sha256" text files that contain the list
of file names and SHA-256 checksums in format compatible with sha256sum program.
7-Zip can work with such checksum files as with archives,
but these files don't contain real file data.
The context menu commands to create and test "sha256" files:
7-Zip / CRC SHA / SHA-256 -> file.sha256
7-Zip / CRC SHA / Test Archive : Checksum
The commands for command line version:
7z a -thash file.sha256 *.txt
7z t -thash file.sha256
7z t -thash -shd. file.sha256
New -shd{dir_path} switch to set the directory that is used to check files
referenced by "file.sha256" file for "Test" operation.
If -shd{dir_path} is not specified, 7-Zip uses the directory where "file.sha256" is stored.
- New -xtd switch to exclude directory items from processing.

-------------------------
- The window "Add to Archive" now allows to set a limit on memory usage (RAM)
that will be used for compressing.
- New switch -mmemuse={N}g / -mmemuse=p{N} to set a limit on memory usage (RAM)
for compressing and decompressing.
