0.9.5 (... ..th 2001)
----------------------
1.0.1 (May 2nd 2001)
--------------------
in short:
intermediate
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:
B129681 - fixed compiler warnings SGI/Irix (thanks Dimitri)
core:
- fixed compiler-warnings Mozilla (thanks Tim)
- fixed timing-problem with switching framing_modes
- fixed some small compiler warnings (thanks Nikki)
- 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!

libmng 0.9.4
libmng 1.0.1
------------
This is the fifth (and last?) beta-release!
First maintenance release!
A few small amendments from the spec, and a couple of minor bug-fixes.
There's been some changes in the CMS profile handling, that should make it
easier for sRGB-compliant systems. Non-sRGB compliant systems will still need
some extra work if they want to use MNG_FULL_CMS with lcms. But this has always
been so, so it's not an extra step anyway.
(Many thanks to Marti, Ivan & Warwick for their help & comments!)
This is another release candidate. If no significant problems are discovered,
libmng 1.0.0 will be just around the corner!
Gregg Kelly has been helpful in locating a couple of memory-leaks, and make
the library even better.
The default Windows DLL that's part of the Windows zip-files now also exports
the JPEG library function calls (ijgsrc6b). Note that there's a new Delphi
component (TNGImage) that makes it a snap to work with PNG/JNG & MNG images
within Delphi.
Please enjoy!
Gerard

*************************************************************************
!!!!!!!! THIS BIT IS IMPORTANT !!!!!!!!!
*************************************************************************
If you have defined MNG_FULL_CMS (and are using lcms), you will have to
think hard about the following routines.
lcms requires 2 profiles to work off the differences in the input-image
and the output-device. The ICC profile for the input-image will be
embedded within it to reflect its color-characteristics, but the output
profile depends on the output-device, which is something only *YOU* know
about. sRGB (standard RGB) is common for x86 compatible environments
(eg. Windows, Linux and some others)
If you are compiling for a sRGB compliant system you probably won't have
to do anything special. (unless you want to ofcourse)
If you are compiling for a non-sRGB compliant system
(eg. SGI, Mac, Next, others...)
you *MUST* define a proper ICC profile for the generic output-device
associated with that platform.
In either event, you may also want to offer an option to your users to
set the profile manually, or, if you know how, set it from a
system-defined default.
TO RECAP: for sRGB systems (Windows, Linux) no action required!
for non-sRGB systems (SGI, Mac, Next) ACTION REQUIRED!
Please visit http://www.srgb.com, http://www.color.org and
http://www.littlecms.com for more info.
