The ChangeLog will follow, but please note the most important change:
LZW compression has been removed.
<p>
Unisys has the patent on LZW compression and have been very active in
their enforcement of late, demanding payments of $5000 or more from
websites using unlicensed software to create GIF's. They could well
do the same do persons using libtiff to create LZW compressed TIFF
images.
<p>
From <A HREF=http://burnallgifs.org>Burn All GIF's Day</a>:
<br>
<em>The catch is that it appears to be difficult or impossible to get a
Unisys license to use LZW in free software that complies with the Open
Source Definition</em>
<P>
Unfortunatly, the removal of LZW compression means that saved image size has
grown dramatically. Without a change in the TIFF spec to support
another lossless compression format, this is unavoidable.
<P>
The library can use zip for lossless compression, but as this is not
part of the spec, TIFFs using zip compression may not work with other
software
<P>
We will be making a patch available that will contain the LZW
compression code for users who have either obtained a license from
Unisys or are willing to risk it.
<p>
LZW decompression is unchanged.
