IX. Y2K Compliance in libpng
May 25, 2002
June 20, 2002
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 1.2.4beta1 are Y2K compliant. It is my belief that earlier
upward through 1.2.4beta2 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
