This document describes the changes made to the software between the

previous and current 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.

The following information is located here:

Changes in the software configuration

Changes in libtiff

Changes in the tools

Changes in the manual pages

Changes in the documentation

Changes in contributed software

<font size="+3">C</font>HANGES IN THE SOFTWARE CONFIGURATION:

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

<font size="+3">C</font>HANGES IN LIBTIFF:

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 <tt>DataType</tt> tag was improved

suppport was added for the <tt>SMinSampleValue</tt>

    and <tt>SMaxSampleValue</tt> tags

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

the support for the <tt>Predictor</tt> 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, <tt>TIFFWriteBufferSetup</tt> was added a la the

   routine <tt>TIFFReadBufferSetup</tt>

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

<font size="+3">C</font>HANGES IN THE TOOLS:

all the tools now use common code to process compress-oriented arguments

<tt>tiffdump</tt> should now compile on a Macintosh with MPW

<font size="+3">C</font>HANGES IN THE MANUAL PAGES:

everything was updated

<font size="+3">C</font>HANGES IN THE DOCUMENTATION:

everything was updated

<font size="+3">C</font>HANGES IN CONTRIBUTED SOFTWARE:

contrib/dbs/xtiff was made to compile

contrib/mac-mpw is new support for compiling the software on

   a Macintosh under MPW; consult the documentation

   for details

contrib/tags is information on how to use the tag extenion

   facilities; consult

   contrib/tags/README for details
