   Y2K compliance in libpng:
   =========================

-      March 7, 2006
+      June 2, 2006

      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 1.2.9beta7 are Y2K compliant.  It is my belief that earlier
+      upward through 1.2.11beta2 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
