Changes predating libungif 3.0 (news in the original libgif, in other words.)
is in ONEWS
Version 4.1.1
=============
* libungif is now available via anonymous cvs! See the libungif web page,
http://prtr-13.ucsc.edu/~badger/software/libungif.shtml
for details.
* If you wish to join libungif development, please join the libungif mailing
list. Details on the libungif web page.
* Merge in many bug fixes that were sent in while I was hiking the
Appalachian Trail.
* The libungif web page is being restructured. Enter the site via this URL:
http://prtr-13.ucsc.edu/~badger/software/libungif/
Version 4.1.0
============
* Several minor memory leaks in error conditions have been plugged.
* New Function EGifOpen(void *userData, OutputFunc writeFunc) allows user
specified gif writing functions.
* Old copyright notices in a few source files have been updated. All library
copyrights should now reflect the copyright notice in the COPYING file.
Version 4.0.0
=============
Major fixes have been made to the code that handles Extensions.
Unfortunately, this causes binary incompatibility with giflib-3.0 and
libungif-3.x. However, the API is still intact. I am, however, deprecating
the use of saveImage[x].Function. Use
saveImage[x].ExtensionBlocks[y].Function instead.
Version 3.1.1
=============
The following bugs which caused SegFaults have been fixed:
* When reading gif files with extensions, DGifSlurp would violate memory.
* When closing a gif that had a local colormap, DGifCloseFile would attempt
to free the colormap twice.
* Fix a potential memory leak in DGifSlurp.
The following enhancements have been made:
* New function DGifOpen to allow specifying a user definable gif reading
function.
Version 3.1.0
=============
* Add a new function:
GifFileType *DGifOpen(void * userData, InputFunc readFunc)
to read the gif image from a user defined input function.
* A few bugfixes.
Version 3.0
===========
Changes from Eric Raymond's libgif:
* A new gif encoder that makes uncompressed gifs rather than standard,
LZW-compressed gifs. This is actually the major motivating factor behind
libungif; to provide third-party distributors a means to provide a gif
library without the patented LZW encoder.
* A new configure script to make compilation of the library on multiple
platforms easier. The package should now build shared libraries on all
platforms supported by GNU libtool.
* Removed the getarg functions from libgif. These were not part of the
public API and only used by the tools in the utils directory so I separated
them from the rest of the library.
* Fixed a few bugs in the tools in the utils directory.
