What's New in Version 24.06 See changelog
Released
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.
24.04 2024-04-05
-------------------------
- 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.
24.03 2024-03-23
-------------------------
- 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 '\'.
- Some bugs were fixed.
24.01 2024-01-31
-------------------------
- 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 GPT 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.
- Some bugs were fixed.
23.01 2023-06-20
-------------------------
- The page "Language" in 7-Zip's menu Tools/Options now shows information
about selected translation, including the number of translated lines.
- Some bugs were fixed.
