is there a reason this tag was removed (in 3.6.0) from the list of tags that are handled by default?

Are you sure? I don't see any problems with that tag.


The TIFFTAG_SOFTWARE tag was changed to be handled as a custom field. It should still work the same at the TIFFGetField() and TIFFSetField() level, but using a different mechanism internally to manage the value. The reason I did this was essentially to ensure that the custom tag support would be in regular use, so bugs would be more quickly identified. It is hoped (by me at least), that in the future more of the "regular" tags that don't require custom processing could be handled in the same manner. That is, just a description of the tag in the tif_dirinfo.c module, with no other special code or entry in the TIFF structure for the tag.
