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:
<UL>
<LI><A HREF="#configure">Changes in the software configuration</A>
<LI><A HREF="#libtiff">Changes in libtiff</A>
<LI><A HREF="#man">Changes in the manual pages</A>
</UL>

<A NAME="configure">CHANGES IN THE SOFTWARE CONFIGURATION:</A>

<UL>
<LI>configure now captures significantly more information
 in the config.log file and provides more information when
 it is unable to setup a configuration
<LI>support was added for building shared libraries on more systems:
 AIX, HPUX, Solaris, and Linux.
<LI>a new configuration parameter <TT>LIBCOPTS</TT> was added for
 passing arguments to the C compiler to use when building only
 the library; this is part of the enhanced support for building
 shared libraries
<LI>include files for optional packages that reside in /usr/include
 are now handled correctly
<LI>build trees may now be configured using either relative or absolute
 pathnames to the source distribution
<LI>several new configuration parameters were added, mainly for building
 shared libraries: <TT>DIST_MAJOR</TT>, <TT>DIST_MINOR</TT>, 
 <TT>DIST_ALPHA</TT>, and <TT>DSOSUF_VERSION</TT>
</UL>

<A NAME="libtiff">CHANGES IN LIBTIFF:</A>

<UL>
<LI>the Deflate support has been revised: it requires version 0.99 of
 the zlib software distribution, the output format has changed and
 is incompatible with previous versions of this library (each
 strip now includes a header read and written by the zlib library)
<LI>the codec name printed by the TIFFPrintDirectory routine is now
 taken from the codec table instead of from a builtin table; this means
 that application-defined codecs are handled correctly
<LI>a new symbol was added that contains the library version number;
 this can be used to do a compile-time compatibility check of the
 library version
</UL>

<A NAME="man">CHANGES IN THE MANUAL PAGES:</A>

<UL>
<LI>the creation and installation of manual pages was redone; it now
 implements the documented ``configuration scheme''
</UL>
