- Update to version 23.01:
* 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.
* 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 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.
* 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.
