It can increase compression speed for 10% for 7z/xz/LZMA/LZMA2 compression. - new `-spo[d|c|r]` switch specifies the path generation mode for the output directory for archive extraction. The output directory path is generated from the path specified in the `-o{dir_path}` switch and the name of the archive being unpacked. `-spod` : for Linux/Posix/macOS: `-o{dir_path}` specifies the direct path to the output directory. The asterisk (`*`) character in {dir_path} will not be replaced by the archive name. `-spoc` : 7-Zip will concatenate the path specified in `-o{dir_path}` with the archive name to form the final path to the output directory. `-spor` : 7-Zip will replace asterisk (`*`) character in the path specified in the `-o{dir_path}` with the archive name. This is the default option. - some bugs were fixed. ### 26.00 - Date: 2026-02-12 - Version: 26.00 - Original notes: https://github.com/ip7z/7zip/releases/tag/26.00 - Permalink: https://whatsnew.fyi/product/7-zip/releases/26.00 - Labels: Platforms: Desktop - **changed** — Improved code for ZIP, CPIO, RAR, UFD, QCOW, Compound formats - **changed** — 7-Zip File Manager improved sorting order of the file list to use file name as secondary sorting key - **changed** — 7-Zip File Manager Benchmark improved to support systems with more than 64 CPU threads - **fixed** — Fixed bug where 7-Zip could not correctly extract TAR archives containing sparse files ###### 7-Zip 26.00 - improved code for ZIP, CPIO, RAR, UFD, QCOW, Compound. - 7-Zip File Manager: improved sorting order of the file list.

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 - Date: 2024-11-30 - Version: 24.09 - Original notes: https://github.com/ip7z/7zip/releases/tag/24.09 - Permalink: https://whatsnew.fyi/product/7-zip/releases/24.09 - Labels: Platforms: Desktop ###### 7-Zip 24.09 - 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. ### 24.08 - Date: 2024-08-12 - Version: 24.08 - Original notes: https://github.com/ip7z/7zip/releases/tag/24.08 - Permalink: https://whatsnew.fyi/product/7-zip/releases/24.08 - Labels: Platforms: Desktop ###### 7-Zip 24.08 - 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 - Date: 2024-06-19 - Version: 24.07 - Original notes: https://github.com/ip7z/7zip/releases/tag/24.07 - Permalink: https://whatsnew.fyi/product/7-zip/releases/24.07 - Labels: Platforms: Desktop ###### 7-Zip 24.07 - The bug was fixed: 7-Zip could crash for some incorrect ZSTD archives. ### 24.06 - Date: 2024-05-27 - Version: 24.06 - Original notes: https://github.com/ip7z/7zip/releases/tag/24.06 - Permalink: https://whatsnew.fyi/product/7-zip/releases/24.06 - Labels: Platforms: Desktop ###### 7-Zip 24.06 - The bug was fixed: 7-Zip could not unpack some ZSTD archives. ### 24.05 - Date: 2024-05-15 - Version: 24.05 - Original notes: https://github.com/ip7z/7zip/releases/tag/24.05 - Permalink: https://whatsnew.fyi/product/7-zip/releases/24.05 - Labels: Platforms: Desktop ###### 7-Zip 24.05 - 7-Zip now can unpack ZSTD archives (.zst filename extension). - 7-Zip now can unpack ZIP, SquashFS and RPM archives that use ZSTD compression method. - 7-Zip now supports fast hash algorithm XXH64 that is used in ZSTD. - 7-Zip now can unpack RAR archives (that use larger than 4 GB dictionary) created by new WinRAR 7.00. - 7-Zip now can unpack DMG archives that use XZ (ULMO/LZMA) compression method. - 7-zip now can unpack NTFS images with cluster size larger than 64 KB. - 7-zip now can unpack MBR and GDP images with 4 KB sectors. - Speed optimizations for archive unpacking: rar, cab, wim, zip, gz. - Speed optimizations for hash caclulation: CRC-32, CRC-64, Blake2sp. - The bug was fixed: 7-Zip for Linux could fail for multivolume creation in some cases. - 7-Zip now can use new RISCV filter for compression to 7z and xz archives. RISCV filter can increase compression ratio for data containing executable files compiled for RISC-V architecture. - The speed for LZMA and LZMA2 decompression in ARM64 version for Windows was increased by 20%-60%. - 7-Zip GUI and 7-Zip File Manager can ask user permission to unpack RAR archives that require big amount of memory, if the dictionary size in RAR archive is larger than 4 GB. - new switch -smemx{size}g : to set allowed memory usage limit for RAR archive unpacking. RAR archives can use dictionary up 64 GB. Default allowed limit for RAR unpacking is 4 GB. - 7zg.exe (7-Zip GUI): -y switch disables user requests and messages. - 7-Zip shows hash methods XXH64 and BLAKE2sp in context menu. - -slmu switch : to show timestamps as UTC instead of LOCAL TIME. - -slsl switch : in console 7-Zip for Windows : to show file paths with linux path separator slash '/' instead of backslash separator '\'. - 7-Zip supports .sha256 files that use backslash path separator '\'. - New menu item in 7-Zip File Manager: "Tools / Delete Temporary Files...". This menu item opens a window showing temporary folders and files created by 7-Zip in the user's "Temp" folder on a Windows system. In this window, the user can delete temporary files. - 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.
