Relevant also for this group. Internal libtiff has just been patched
with the changes mentioned below.
I'd recommend sticking with libjpeg-turbo (preferred option) or IJG
libjpeg 6b, 7.x or 8.x

A word of caution for those using mozjpeg or IJG libjpeg 9d for creating
JPEG-in-TIFF files. It has been found that current libtiff releases can
generate non-conformant (mozjpeg case) or broken (libjpeg 9d case)
files. See https://gitlab.com/libtiff/libtiff/-/issues/266 for more details.
https://gitlab.com/libtiff/libtiff/-/merge_requests/255 have been merged
with workarounds to make libtiff work with those JPEG libraries.
My software is free, but my time generally not.
