7-Zip - 更新履歴

24.01 Beta
  • 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.
  • Some bugs were fixed.
23.01
  • 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.
23.00
  • 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.
22.01
  • UDF support was improved to UDF version 2.60.
  • HFS and APFS support was improved.
22.00
  • 7-Zip now can extract APFS (Apple File System) images that can be used in DMG files.
  • 7-Zip now can create TAR archives in POSIX (pax) tar format with the switches
    -ttar -mm=pax or -ttar -mm=posix
  • 7-Zip now can store additional file timestamps with high precision (1 ns in Linux) in tar/pax archives with the following switches:
    -ttar -mm=pax -mtp=3 -mtc -mta
  • New switches for Linux version for TAR archives:
    -snoi : store owner/group ids in archive or set owner/group ids from archive to extracted files.
    -snon : store owner/group names in archive
  • New -snz switch to propagate Zone.Identifier stream to extracted files (Windows).
  • New option "Propagate Zone.Id stream" in Tools/Options/7-Zip menu.
  • New "Options" window in "Add to archive" allows to select what metadata must be included to archive. Also it allows to select new option
    "Do not change source files last access time".
  • Some bugs were fixed.
21.07
  • 7-Zip now can extract VHDX disk images (Microsoft Hyper-V Virtual Hard Disk v2 format).
  • New switches: -spm and -im!{file_path} to exclude directories from processing
  • For specified paths that don't contain path separator character at the end of path.
  • In the "Add to Archive" window, now it is allowed to use -m prefix for "Parameters" field as in command line: -mparam.
  • Sorting order of files in archives was slightly changed to be more consistent
  • For cases where the name of some directory is the same as the prefix part of the name of another directory or file.
  • TAR archives created by 7-Zip now are more consistent with archives created by GNU TAR program.
21.06
  • The window "Add to Archive" now allows to set a limit on memory usage (RAM) that will be used for compressing.
  • New switch -mmemuse={N}g / -mmemuse=p{N} to set a limit on memory usage (RAM) for compressing and decompressing.
  • Bug in versions 21.00-21.05 was fixed: 7-Zip didn't set attributes of directories during archive extracting.
  • Some bugs were fixed.
21.04 Beta
  • 7-Zip now reduces the number of working CPU threads for compression, if RAM size is not enough for compression with big LZMA2 dictionary.
  • 7-Zip now can create and check "file.sha256" text files that contain the list of file names and SHA-256 checksums in format compatible with sha256sum program.
    7-Zip can work with such checksum files as with archives, but these files don't contain real file data.
    The context menu commands to create and test "sha256" files:
  • New -shd{dir_path} switch to set the directory that is used to check files referenced by "file.sha256" file for "Test" operation. If -shd{dir_path} is not specified, 7-Zip uses the directory where "file.sha256" is stored.
  • New -xtd switch to exclude directory items from processing.
21.03 Beta
  • The maximum dictionary size for LZMA/LZMA2 compressing was increased to 4 GB (3840 MiB).
  • Minor speed optimizations in LZMA/LZMA2 compressing.
21.02 alpha
  • 7-Zip now writes additional field for filename in UTF-8 encoding to zip archives.
    It allows to extract correct file name from zip archives on different systems.
  • The command line version of 7-Zip for macOS was released.
  • The speed for LZMA and LZMA2 decompression in arm64 versions for macOS and Linux was increased by 20%-60%.
  • Some changes and improvements in ZIP, TAR and NSIS code.
