7-Zip 24.09 fixes:

  • The default dictionary size values for LZMA/LZMA2 compression methods were increased.
  • The default dictionary size values for 32-bit versions of LZMA/LZMA2 don't exceed 64 MB.
  • 7-Zip now can calculate the following hash checksums: SHA-512, SHA-384, SHA3-256 and MD5.
  • APM and HFS support was improved.
  • If an archive update operation uses a temporary archive folder and the archive is moved to the destination folder, 7-Zip shows the progress of moving the archive file, as this operation can take a long time if the archive is large.
  • The bug was fixed: 7-Zip File Manager didn't propagate Zone.Identifier stream for extracted files from nested archives (if there is open archive inside another open archive).
  • Some bugs were fixed.
