 IX. Y2K Compliance in libpng
 
-November 6, 2007
+November 20, 2007
 
 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 1.2.23 are Y2K compliant.  It is my belief that earlier
+upward through 1.2.24beta01 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

 .SH IX. Y2K Compliance in libpng
 
-November 6, 2007
+November 20, 2007
 
 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 1.2.23 are Y2K compliant.  It is my belief that earlier
+upward through 1.2.24beta01 are Y2K compliant.  It is my belief that earlier
 versions were also Y2K compliant.
