$$$25.00 2025-07-05$$$-------------------------$$$- 7-Zip for Windows can now use more than 64 CPU threads for compression$$$ to zip/7z/xz archives and for the 7-Zip benchmark.$$$ If there are more than one processor group in Windows (on systems with more than$$$ 64 cpu threads); 7-Zip distributes running CPU threads across different processor groups.$$$- bzip2 compression speed was increased by 15-40%.$$$- deflate (zip/gz) compression speed was increased by 1-3%.$$$- improved support for zip; cpio and fat archives.$$$- fixed some bugs and vulnerabilities.

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 dont 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 didnt propagate Zone.Identifier stream$$$ for extracted files from nested archives (if there is open archive inside another open archive).$$$- Some bugs were fixed.

24.08 2024-08-11$$$-------------------------$$$- The bug in 7-Zip 24.00-24.07 was fixed:$$$ For creating a zip archive: 7-Zip could write extra zero bytes after the end of the archive;$$$ if a file included to archive cannot be compressed to a size smaller than original.$$$ The created zip archive is correct except for the useless zero bytes after the end of the archive.$$$ When unpacking such a zip archive; 7-Zip displays a warning:$$$ WARNING: There are data after the end of archive.$$$- The bug was fixed: there was a leak of GDI objects (internal resources in Windows)$$$ in Confirm File Replace window; causing problems after 1600 displays of Confirm File Replace$$$ window from same running 7-Zip process.$$$- Some optimizations for displaying file icons in 7-Zip File Manager and in Confirm File Replace window.$$$- Some bugs were fixed.

24.07 2024-06-19$$$-------------------------$$$- The bug was fixed: 7-Zip could crash for some incorrect ZSTD archives.

24.06 2024-05-26$$$-------------------------$$$- The bug was fixed: 7-Zip could not unpack some ZSTD archives.

24.05 2024-05-14$$$-------------------------$$$- New switch -myv={MMNN} to set decoder compatibility version for 7z archive creating.$$$ {MMNN} is 4-digit number that represents the version of 7-Zip without a dot.$$$ If -myv={MMNN} switch is specified; 7-Zip will only use compression methods that can $$$ be decoded by the specified version {MMNN} of 7-Zip and newer versions.$$$ If -myv={MMNN} switch is not specified; -myv=2300 is used; and 7-Zip will only$$$ use compression methods that can be decoded by 7-Zip 23.00 and newer versions.$$$- New switch -myfa={FilterID} to allow 7-Zip to use the specified filter method for 7z archive creating.$$$- New switch -myfd={FilterID} to disallow 7-Zip to use the specified filter method for 7z archive creating.$$$- Some bugs were fixed.

- UDF support was improved to UDF version 2.60.$$$- HFS and APFS support was improved.

23.01 2023-06-20$$$-------------------------$$$- The page Language in 7-Zips menu Tools/Options now shows information$$$ about selected translation; including the number of translated lines.
