Y2K compliance in libpng:
=========================
February 18, 2008
April 2, 2008
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 1.0.31 are Y2K compliant. It is my belief that earlier
upward through 1.0.32 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
Libpng only has three year fields. One is a 2-byte unsigned integer
