New beta out: 7-Zip / Discussion /
Open Discussion: 7-Zip 21.04 beta

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.

Hi there

@Cliff S


Thanks for the update.

I can confirm at least on my systems it works also on W11 both the standard build 282 and the " dev preview builds too.

It's also available on Linux as well.

Have used this program for years -- called 7z-FM on linux

- 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.
- Some bugs were fixed.


First final version in 2 years

nice!
