Chris,

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.

Best regards,
