Y2K compliance in libpng:
=========================
August 7, 2017
August 18, 2017
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 1.2.58beta01 are Y2K compliant. It is my belief that earlier
upward through 1.2.58rc01 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
