Some bugs fixed.

7-New features after Zip 22.01:

- 7-Zip can now compress files into 7z and xz archives using the new ARM64 filter. The ARM64 filter can improve the compression ratio and is suitable for files containing Data for executable files compiled for ARM64 (AArch64) architecture. Additionally, 7-Zip now parses executable files (both exe and dll) before zipping filename extension) and select the appropriate filter for each parsed file;

- For x86 executables, use BCJ or BCJ2 filters;

- For ARM64 executables, use the ARM64 filter. Previous versions used x86 filter BCJ or BCJ2.

- BCJ2 filter default segment size changed from 64 MiB to 240 MiB. This improves compression ratio for executable files larger than 64 MiB.

- Improved UDF support.

- cpio: support hard links.

- Some changes and optimizations to the WIM creation code.

- When a new 7-Zip creates a multi-volume archive, 7-Zip only keeps open the volumes that can still be changed. Previous versions kept all volumes open until the end of archive creation.

- On Linux and macOS systems, when 7-Zip opens, extracts or creates a multi-volume archive 7-Zip It is now possible to reduce the number of files open at the same time. This avoids failures caused by large volume numbers, as there are limits in Linux and macOS on the number of files a single program is allowed to open.

- 7-Zip has optimizations in the code of the context menu in Explorer: 7-Zip is included in external programs The context menu for menu commands improves the speed of preparing the menu for display when selecting a large number of files.

- The code for drag-and-drop operations in the 7-Zip file manager has been changed, and right-click drag-and-drop operations are also supported in some cases.

Bug fixed:

- ZIP archive: If you use multi-threaded ZIP compression to compress multiple files to the stdout stream (-so option), 7-Zip No 'data descriptors' were written for some files.

- ext4 archives: 7-Zip does not correctly extract symlinks to directories from ext4 archives.

- HFS and APFS archives: 7-Zip incorrectly decoded uncompressed chunks (64 KiB) in the compression fork.

- Fixed other known bugs.
