- update to 4.6.1:
* Race condition which can cause corruption of the "fragment
table" fixed. This is a regression introduced in August 2022,
and it has been seen when tailend packing is used (-tailends option).
* Fix build failure when the tools are being built without
extended attribute (XATTRs) support.
* Fix XATTR error message when an unrecognised prefix is
found
* Fix incorrect free of pointer when an unrecognised XATTR
prefix is found.
* Major improvements in extended attribute handling,
pseudo file handling, and miscellaneous new options and
improvements
* Extended attribute handling improved in Mksquashfs and
Sqfstar
* New Pseudo file xattr definition to add extended
attributes to files.
* New xattrs-add Action to add extended attributes to files
* Extended attribute handling improved in Unsquashfs
* Other major improvements
* Unsquashfs can now output Pseudo files to standard out.
* Mksquashfs can now input Pseudo files from standard in.
* Squashfs filesystems can now be converted (different
block size compression etc) without unpacking to an
intermediate filesystem or mounting, by piping the output of
Unsquashfs to Mksquashfs.
* Pseudo files are now supported by Sqfstar.
* "Non-anchored" excludes are now supported by Unsquashfs.
