Hi all, Due to Adobe no longer assigning TIFF tags / tags value, and someone mentionning that the previously values use for COMPRESSION_ZSTD and COMPRESSION_WEBP were already taken, those have been just changed:
https://gitlab.com/libtiff/libtiff/commit/126a949736fe8d2684525706e9047b39e2a095a6 I'll resynchronize the internal GDAL copy with that, which means that if you have existing TIFF file using ZStd / WebP compression, they will no longer be recognized. I imagine we could come with a hack to still recognize the old values, but I don't plan to go to that complication unless really needed.

I just submitted a changeset such that COMPRESSION_ZSTD is changed to 50000 and COMPRESSION_WEBP is changed to 50001.
