   473 detected during testing. It adds the proposed change to the MNG spec as

   474 discussed on the "mng-list" recently; eg. Adam's option 4.

   475 And it adds a little function to check at run-time if the lib is a beta or not.

   695 Maintenance release.

   697 handling, exported JPEG functions from standard DLL, and some other minor fixes.

   698 

   699 The CMS fix now makes libmng automagically work in MNG_FULL_CMS mode as a

   700 sRGB compliant system. YOU WILL NEED TO CHANGE THIS IF YOU ARE NOT ON AN sRGB

   701 COMPLIANT SYSTEM AND WANT TO USE CMS!!!!

   702 (look in libmng.h for the proper function-calls)

   703

   734 1.0.0 (Feb 6th 2001)

   735 --------------------

   736 

   737 in short:

   738 

   739 First public release. Finally(!)

   740 

   741 This is the 0.9.5 CVS version, which will never be released, because I feel it

   742 is now ready for a public release. So apart from the version-numbers here and

   743 there, all other changes are listed under 0.9.5.

   744 

   745 This library will work with every MNG/JNG known and available to me. Note that

   746 there are still parts that need to be coded, and that MNG support is around

   747 90-95% (JNG at 100%). It is however compliant with the latest and greatest

   748 MNG 1.0 specification.

   749 

   750 I hope to dedicate a bit more time this year to finish up full support and fill

   751 in the remaining blanks. But this is coming out of my spare time. And extra

   752 help is always appreciated.

   753 

   754 Please enjoy!

   864 libmng 1.0.0 very shortly after this one.

  1099 Thanks to all the people who helped to guide me in the right direction.

  1100 You know who you are!

  1101 

  1102 A special thanks to the guys with early implementations, who stood by and

  1103 put up with my whims :-)

  1104

  1106 

  1107 - updated mngplg to 0.4.1 (the latest & greatest)

  1116 

  1117 This is a working version only; the next release will be 0.9.0 (first Beta!)

  1118 

  1119 There are a few incompatible changes with previous versions. The userdata

  1120 variable has been changed from mng_uint32 to mng_ptr to accomodate 64-bit

  1121 systems. For the same reason memory allocation size parameters have been

  1122 changed to a mng_size_t type which is a typedef of size_t.
