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

       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 1.4.0beta2 are Y2K compliant.  It is my belief that earlier
+      upward through 1.2.14beta2 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
