0.9.0 (June 30th 2000)
----------------------

in short:

This is the first beta!!! Yippee!!!

Thanks to all the people who helped to guide me in the right direction.
You know who you are!

A special thanks to the guys with early implementations, who stood by and
put up with my whims :-)

changes over 0.5.3:

- updated mngplg to 0.4.1 (the latest & greatest)

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

0.5.3 (never released)
----------------------

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

There are a few incompatible changes with previous versions. The userdata
variable has been changed from mng_uint32 to mng_ptr to accomodate 64-bit
systems. For the same reason memory allocation size parameters have been
changed to a mng_size_t type which is a typedef of size_t.
