+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 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!!!
