Hi,

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/254 and https://gitlab.com/libtiff/libtiff/-/merge_requests/255 have been merged with workarounds to make libtiff work with those JPEG libraries.
