17. Appendix: Revision History

(This appendix is not part of the formal PNG specification.)

The PNG format has been frozen since the Ninth Draft of March 7, 1995, and all future changes are intended to be backwards compatible. The revisions since the Ninth Draft are simply clarifications, improvements in presentation, and additions of supporting material.

On 1 October 1996, the PNG specification was approved as a W3C (World Wide Web Consortium) Recommendation. At that time, it was awaiting publication as an Informational RFC.

Changes since the Tenth Draft of 5 May, 1995
