News and History of the PNG Development Group from 2013
Herein lie news items and historical stuff primarily of interest to the
Portable Network Graphics Development Group itself. Feel free to poke

later entries. Other links (CompuServe, tcg.arl.mil) have fallen prey to
reorganizations or upgrades; should they ever reappear, the entries below
will be updated as needed.
