I raise the motion to adopt the libtiff 4.7.2rc4 release candidate as
the 4.7.2 release.

This release candidate is passing the various tests I have available
as pertains to GraphicsMagick.

Hi again,

yes a rc4 was needed. It consists of, compared to rc3:

- reverting the JBIG rc3 change that seems to introduce a new
vulnerability:
https://gitlab.com/libtiff/libtiff/-/merge_requests/914

- revert the rc3 change related to byte-swapping that apparently
causes some legit images to be incorrectly decoded: https://
gitlab.com/libtiff/libtiff/-/merge_requests/915 . Side effect is that
bug https://gitlab.com/libtiff/libtiff/-/work_items/795 will be re-
opened. Good luck to anyone trying to fix it without causing
regressions :-)

- a minor rst formatting fix: https://gitlab.com/libtiff/libtiff/-/
merge_requests/913

New RC tarballs at:

- https://download.osgeo.org/libtiff/tiff-4.7.2rc4.tar.gz
- https://download.osgeo.org/libtiff/tiff-4.7.2rc4.tar.xz
- https://download.osgeo.org/libtiff/tiff-4.7.2rc4.zip

I let another PSC member raise the motion to adopt it, as it seems my
attempts at doing so don't bring favorable fate :-)

(despite the frustration of having to iterate on this release, thanks
to all those who have tested it and reported. Given the unusual
amount of activity since last release, and our known to be quite
partial test suite, it is quite expected we hit regressions)

Even
