libmng v0.9.3
-------------
libmng 0.9.4
------------
This is the fourth beta-release!
This is the fifth (and last?) beta-release!
Quite a few changes, since there has been several changes in the MNG spec.
Also fixes a number of problems that have surfaced during extensive tests.
And a number of functions have been added to facilitate in integrating
the library in a multitude of applications, as these were the result of
requests from several implementors.
A few small amendments from the spec, and a couple of minor bug-fixes.
This is another release candidate. If no significant problems are discovered,
libmng 1.0.0 will be just around the corner!
