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 manual pages

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

configure now captures significantly more information

   in the config.log file and provides more information when

   it is unable to setup a configuration

support was added for building shared libraries on more systems:

   AIX, HPUX, Solaris, and Linux.

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

include files for optional packages that reside in /usr/include

   are now handled correctly

build trees may now be configured using either relative or absolute

   pathnames to the source distribution

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>

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

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)

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

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

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

the creation and installation of manual pages was redone; it now

    implements the documented ``configuration scheme''

 TIFF home page.
