|
|
- UDF support was improved to UDF version 2.60.
|
|
- HFS and APFS support was improved.
|
|
|
|
|
|
22.00 2022-06-15
|
|
-------------------------
|
|
- 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 2021-12-26
|
|
-------------------------
|
|
- 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.
|
|
- The 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 2021-11-24
|
|
-------------------------
|
|
- 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 2021-11-02
|
|
-------------------------
|
|
- 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:
|
|
7-Zip / CRC SHA / SHA-256 -> file.sha256
|
|
7-Zip / CRC SHA / Test Archive : Checksum
|
|
The commands for command line version:
|
|
7z a -thash file.sha256 *.txt
|
|
7z t -thash file.sha256
|
|
7z t -thash -shd. file.sha256
|
|
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 metadata records from processing.
|
|
|
|
|
|
21.03 beta 2021-07-20
