release notes:
5.4.6 (2024-01-26)
* Fixed a bug involving internal function pointers in liblzma not
being initialized to NULL. The bug can only be triggered if
lzma_filters_update() is called on a LZMA1 encoder, so it does
not affect xz or any application known to us that uses liblzma.
* xz:
- Fixed a regression introduced in 5.4.2 that caused encoding
in the raw format to unnecessarily fail if --suffix was not
used. For instance, the following command no longer reports
that --suffix must be used:
echo foo | xz --format=raw --lzma2 | wc -c
- Fixed an issue on MinGW-w64 builds that prevented reading
from or writing to non-terminal character devices like NUL.
* Added a new test.
