Y2K compliance in libpng:
=========================

Since the PNG Development group is an ad-hoc body, we can't make
an official declaration.
This is your unofficial assurance that libpng from version 0.71 and
- upward through 1.2.6 are Y2K compliant. It is my belief that earlier
+ upward through 1.2.7beta1 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
