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

52
53<UL>
54<LI>support was added for registering new codecs external to the library
55   and for overriding the codecs that are builtin to the library
56<LI>emulation support for the old <TT>DataType</TT> tag was improved
57<LI>suppport was added for the <TT>SMinSampleValue</TT>
58    and <TT>SMaxSampleValue</TT> tags
59<LI>the library no longer ignores <TT>TileWidth</TT> and <TT>TileLength</TT>
60    tags whose values are not a multiple of 16 (per the spec); this
61    permits old, improperly written, images to be read
62<LI>the support for the <TT>Predictor</TT> tag was placed in a reusable
63    module so that it can be shared by multiple codecs
64<LI>experimental compression support was added for the Deflate algorithm
65   (using the freely available zlib package)
66<LI>a new routine, <TT>TIFFWriteBufferSetup</TT> was added a la the
67   routine <TT>TIFFReadBufferSetup</TT>
68<LI>the DSO version of the library is now statically linked with the
69   JPEG and Deflate libraries; this means applications that link against
70   the DSO do not also need to link against these ancillary libraries
