24.09          2024-11-29
-------------------------
- The default dictionary size values for LZMA/LZMA2 compression methods were increased:
         dictionary size   compression level
  v24.08  v24.09  v24.09
          32-bit  64-bit
    8 MB   16 MB   16 MB   -mx4
   16 MB   32 MB   32 MB   -mx5 : Normal
   32 MB   64 MB   64 MB   -mx6
   32 MB   64 MB  128 MB   -mx7 : Maximum
   64 MB   64 MB  256 MB   -mx8
   64 MB   64 MB  256 MB   -mx9 : Ultra
  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.
