| 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.

|

| 39 | <UL>
|
|---|
| 40 | <LI><B>configure</B> now captures significantly more information
|
|---|
| 41 | in the <B>config.log</B> file and provides more information when
|
|---|
| 42 | it is unable to setup a configuration
|
|---|
| 43 | <LI>support was added for building shared libraries on more systems:
|
|---|
| 44 | AIX, HPUX, Solaris, and Linux.
|
|---|
| 45 | <LI>a new configuration parameter <TT>LIBCOPTS</TT> was added for
|
|---|
| 46 | passing arguments to the C compiler to use when building only
|
|---|
| 47 | the library; this is part of the enhanced support for building
|
|---|
| 48 | shared libraries
|
|---|
| 49 | <LI>include files for optional packages that reside in <B>/usr/include</B>
|
|---|
| 50 | are now handled correctly
|
|---|
| 51 | <LI>build trees may now be configured using either relative or absolute
|
|---|
| 52 | pathnames to the source distribution
|
|---|
| 53 | <LI>several new configuration parameters were added, mainly for building
|
|---|
| 54 | shared libraries: <TT>DIST_MAJOR</TT>, <TT>DIST_MINOR</TT>,
|
|---|
| 55 | <TT>DIST_ALPHA</TT>, and <TT>DSOSUF_VERSION</TT>

|

|
|---|
| 63 | <LI>the Deflate support has been revised: it requires version 0.99 of
|
|---|
| 64 | the zlib software distribution, <B>the output format has changed and
|
|---|
| 65 | is incompatible with previous versions of this library</B> (each
|
|---|
| 66 | strip now includes a header read and written by the zlib library)
|
|---|
| 67 | <LI>the codec name printed by the TIFFPrintDirectory routine is now
|
|---|
| 68 | taken from the codec table instead of from a builtin table; this means
|
|---|
| 69 | that application-defined codecs are handled correctly
|
|---|
| 70 | <LI>a new symbol was added that contains the library version number;
|
|---|
| 71 | this can be used to do a compile-time compatibility check of the
|
|---|
| 72 | library version

|
|---|
| 80 | <LI>the creation and installation of manual pages was redone; it now
|

| 81 | implements the documented ``configuration scheme''
