What's new after 7-Zip 22.01:
  • 7-Zip now can use new ARM64 filter for compression to 7z and xz archives. ARM64 filter can increase compression ratio for data containing executable files compiled for ARM64 (AArch64) architecture.
  • Also 7-Zip now parses executable files (that have exe and dll filename extensions) before compressing, and it selects appropriate filter for each parsed file:
  • BCJ or BCJ2 filter for x86 executable files,
  • ARM64 filter for ARM64 executable files.
  • Previous versions by default used x86 filter BCJ or BCJ2 for all exe/dll files.
  • Default section size for BCJ2 filter was changed from 64 MiB to 240 MiB. It can increase compression ratio for executable files larger than 64 MiB.
  • UDF: support was improved.
  • cpio: support for hard links.
  • Some changes and optimizations in WIM creation code.
  • When new 7-Zip creates multivolume archive, 7-Zip keeps in open state only volumes that still can be changed. Previous versions kept all volumes in open state until the end of the archive creation.
  • 7-Zip for Linux and macOS now can reduce the number of simultaneously open files, when 7-Zip opens, extracts or creates multivolume archive. It allows to avoid the failures for cases with big number of volumes, bacause there is a limitation for number of open files allowed for a single program in Linux and macOS.
  • There are optimizations in code for 7-Zip's context menu in Explorer: the speed of preparing of the menu showing was improved for cases when big number of files were selected by external program for context menu that contains 7-Zip menu commands.
  • There are changes in code for the drag-and-drop operations to and from 7-Zip File Manager.
  • And the drag-and-drop operation with right button of mouse now is supported for some cases.

The bugs were fixed:
  • ZIP archives: if multithreaded zip compression was performed with more than one file to stdout stream (-so switch), 7-zip didn't write "data descriptor" for some files.
  • ext4 archives: 7-Zip couldn't correctly extract symbolic link to directory from ext4 archives.
  • HFS and APFS archives: 7-Zip incorrectly decoded uncompressed blocks (64 KiB) in compressed forks.
  • Some another bugs were fixed.

The main improvement of 7-Zip 23.00 Beta affects the program's handling of executable files. The new release includes support for the ARM64 filter when compressing ARM64 executable files to 7z or xz archives.

The new filter may improve the compression ratio of ARM64 executable files when using 7-zip. The compression software parses executable files that users have selected for compression now to determine the best filter for them. The ARM64 filter is selected for ARM64 executable files, the traditional BCJ and BCJ2 filters for x86 executable files.

The section size of the BCJ2 filter has been raised from 64 MiB to 240 MiB (that is mebibyte, not Men in Black). The change may improve the compression ratio of executable files that are larger than 64 MiB according to the release notes.

7-Zip 23.00 Beta includes a number of additional changes and fixes. Support for UDF has improved and cpio supports hard links now. The creation of multivolume archives has been improved for macOS and Linux devices.

Both Linux and macOS limit the number of open files that a single program can have. To avoid issues with "big number of volumes", 7-Zip may now limit the number of simultaneously open files on these platforms during open, extraction and creation operations.

The release notes list two code changes. The first improves drag and drop operations that involve the right mouse button. The second improves the speed in which the 7-Zip menu is displayed in Explorer under specific use cases.

What's new in 7-Zip 24.02:​

  • 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.

    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 '\'.

HISTORY of the 7-Zip
--------------------
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.
