News and History of the PNG Development Group from 2010

Herein lie news items and historical stuff primarily of interest to the Portable Network Graphics Development Group itself. Feel free to poke around even if you're not a member, though. Note that some of the links, particularly the older ones, are broken; in some cases this is explained by 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.

Keep in mind that this is history here...

• current - see here

• 27 February 2010 - libpng 1.4.1 is released with various fixes, including significantly better performance when decoding highly compressed chunks and a fix for a potential memory leak. (libpng 1.2.43 is also released with the same fixes.)

• 3 January 2010 - libpng 1.4.0 is released at long last! It adds support for the PNG international text (iTXt) chunk, includes a new security-related function to limit total memory allocations, removes a bunch of long-deprecated functions and features, and includes some new cleanups. See the summary for details. (libpng 1.2.42 is also released with some minor fixes.)
