<A NAME="configure">CHANGES IN THE SOFTWARE CONFIGURATION:</A>

<UL>
<LI>support was added for configuring the Deflate codec
<LI>support was added for the HTML documentation
<LI>codecs that are not configured for inclusion in the library
 are no longer compiled
</UL>

<A NAME="libtiff">CHANGES IN LIBTIFF:</A>

<UL>
<LI>support was added for registering new codecs external to the library
 and for overriding the codecs that are builtin to the library
<LI>emulation support for the old <TT>DataType</TT> tag was improved
<LI>suppport was added for the <TT>SMinSampleValue</TT>
 and <TT>SMaxSampleValue</TT> tags
<LI>the library no longer ignores <TT>TileWidth</TT> and <TT>TileLength</TT>
 tags whose values are not a multiple of 16 (per the spec); this
 permits old, improperly written, images to be read
<LI>the support for the <TT>Predictor</TT> tag was placed in a reusable
 module so that it can be shared by multiple codecs
<LI>experimental compression support was added for the Deflate algorithm
 (using the freely available zlib package)
<LI>a new routine, <TT>TIFFWriteBufferSetup</TT> was added a la the
 routine <TT>TIFFReadBufferSetup</TT>
<LI>the DSO version of the library is now statically linked with the
 JPEG and Deflate libraries; this means applications that link against
 the DSO do not also need to link against these ancillary libraries
</UL>
