Y2K compliance in libpng:
=========================
October 25, 2001
October 27, 2001
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 1.2.1beta2 are Y2K compliant. It is my belief that earlier
upward through 1.2.1beta3 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
