| This document describes the changes made to the software between the | |
| <I>previous</I> and <I>current</I> 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. | |

| <A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A> | |
| <UL> | |
| <LI><B>configure</B> now captures significantly more information | |
| in the <B>config.log</B> 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 <B>/usr/include</B> | |
| 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> | |
| <P><HR WIDTH=65% ALIGN=right> | |
| <A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A> | |
| <UL> | |
| <LI>the Deflate support has been revised: it requires version 0.99 of | |
| the zlib software distribution, <B>the output format has changed and | |
| is incompatible with previous versions of this library</B> (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> | |
| <P><HR WIDTH=65% ALIGN=right> | |
| <A NAME="man"><B><FONT SIZE=+3>C</FONT>HANGES IN THE MANUAL PAGES:</B></A> | |
| <UL> | |
| <LI>the creation and installation of manual pages was redone; it now | |
| implements the documented ``configuration scheme'' | |
