21.04 beta

7-zip 21.04 beta with NSIS script decompiling

• 7z****-x64.exe: 7-Zip for 64-bit Windows (x64).
• 7z****-x86.exe: 7-Zip for 32-bit Windows (x86).
• 7z****.7z: Everything compiled.

Compatibility

• 7-Zip for 64-bit Windows (x64): Windows Vista and above.
• 7-Zip for 32-bit Windows (x86): Windows XP (maybe) and above.

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.
