VIII. Y2K Compliance in libpng
December 28, 2000
January 12, 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 1.0.9beta7 are Y2K compliant. It is my belief that earlier
upward through 1.0.9beta8 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 that
