  24 This document describes the changes made to the software between the
  25 <I>previous</I> and <I>current</I> versions (see above).
  26 If you don't find something listed here, then it was not done in this
  27 timeframe, or it was not considered important enough to be mentioned.

  41
  42 <UL>
  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
