+<I>previous</I> and <I>current</I> versions (see above).
+If you don't find something listed here, then it was not done in this
+timeframe, or it was not considered important enough to be mentioned.

+<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

+<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></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
