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. The following information is located here: Software configuration changes ------------------------------ * support was added for configuring the Deflate codec * support was added for the HTML documentation * codecs that are not configured for inclusion in the library are no longer compiled Library changes --------------- * support was added for registering new codecs external to the library and for overriding the codecs that are builtin to the library * emulation support for the old ``DataType`` tag was improved * support was added for the ``SMinSampleValue`` and ``SMaxSampleValue`` tags * the library no longer ignores ``TileWidth`` and ``TileLength`` tags whose values are not a multiple of 16 (per the spec); this permits old, improperly written, images to be read * the support for the ``Predictor`` tag was placed in a reusable module so that it can be shared by multiple codecs * experimental compression support was added for the Deflate algorithm (using the freely available zlib package) * a new routine, :c:func:`TIFFWriteBufferSetup` was added à la the routine :c:func:`TIFFReadBufferSetup` * 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 Tools changes ------------- * all the tools now use common code to process compress-oriented arguments * :program:`tiffdump` should now compile on a Macintosh with MPW Documentation changes --------------------- * everything was updated Contributed software changes ---------------------------- * :file:`contrib/dbs/xtiff` was made to compile * :file:`contrib/mac-mpw` is new support for compiling the software on a Macintosh under MPW * :file:`contrib/tags` is information on how to use the tag extenion facilities; consult :file:`contrib/tags/README` for details
