* Y2K compliance in libpng:
* =========================
*
- * December 27, 2006
+ * December 29, 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 1.0.23rc4 are Y2K compliant. It is my belief that earlier
+ * upward through 1.0.23rc5 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
