Version 0.89 was the first official release of libpng. Don't let the
fact that it's the first release fool you. The libpng library has been in
critical or an ancillary chunk.
The changes made to the library, and bugs fixed are based on discussions
-on the PNG-implement mailing list
-and not on material submitted privately to Guy, Andreas, or Glenn. They will
-forward any good suggestions to the list.

For a detailed description on using libpng, read libpng.txt. For
examples of libpng in a program, see example.c and pngtest.c. For usage
fix. Please mention "libpng" somewhere in the subject line. Thanks.
This release was created and will be supported by myself (of course
-based in a large way on Guy's and Andreas' earlier work), and the PNG group.
