<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+ −
