in short:

First beta of a large maintenance release. This completes support of the MNG
specification to nearly 100% (PAST, PROM, delta-images, BACK image+tile).

1.0.1 (May 2nd 2001)
--------------------

in short:

Maintenance release.
Fixed several memory-leaks with the help of Gregg Kelly, added/fixed some CMS
handling, exported JPEG functions from standard DLL, and some other minor fixes.

The CMS fix now makes libmng automagically work in MNG_FULL_CMS mode as a
sRGB compliant system. YOU WILL NEED TO CHANGE THIS IF YOU ARE NOT ON AN sRGB
COMPLIANT SYSTEM AND WANT TO USE CMS!!!!
(look in libmng.h for the proper function-calls)

-------------------

bugfixes:

core:
- added MEND processing callback
- fixed first FRAM_MODE=4 timing problem
- added handle status-copy function (use with care)
- exported JPEG functions from standard DLL
- added BGRA8 canvas with premultiplied alpha (contrib by Gregg Kelly)
- fixed problem with display_reset/display_resume (Thanks Gregg!)
- fixed several memory-leaks (Thanks Gregg!)
- fixed reset_rundata to drop all objects (Thanks again, Gregg!)
- fixed problem with cms profile being created multiple times when both
  iCCP & cHRM/gAMA are present (And again... Gregg)
- moved mng_clear_cms to libmng_cms
- added "default" sRGB generation (Thanks Marti!)

1.0.0 (Feb 6th 2001)
--------------------

in short:

First public release. Finally(!)

This is the 0.9.5 CVS version, which will never be released, because I feel it
is now ready for a public release. So apart from the version-numbers here and
there, all other changes are listed under 0.9.5.

This library will work with every MNG/JNG known and available to me. Note that
there are still parts that need to be coded, and that MNG support is around
90-95% (JNG at 100%). It is however compliant with the latest and greatest
MNG 1.0 specification.

I hope to dedicate a bit more time this year to finish up full support and fill
in the remaining blanks. But this is coming out of my spare time. And extra
help is always appreciated.

Please enjoy!

Gerard

0.9.3 (October 29th 2000)
-------------------------

in short:

Another beta release. The number of changes in the MNG specification have
resulted in a lot of new code and some changed code. At the same time I saw
no need to withhold some new functionality as it was pretty clear there was
going to be another beta-round. If things go well, I'm going to try to release
libmng 1.0.0 very shortly after this one.

Many thanks to a lot of people for helping out, sending contributions, making
suggestions and testing this little baby. This would get nowhere without YOU!!!
