News and History of the PNG Development Group from 2009

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

• 3 December 2009 - libpng 1.2.41 is released with cleanups, a new xcode build setup, and a minor performance improvement (avoid building 16-bit gamma tables when not needed). Some new warnings designed to aid porting to the upcoming libpng 1.4.x can be enabled by defining PNG_PEDANTIC_WARNINGS.

• 10 September 2009 - libpng 1.2.40 is released with a minor fix for unknown-chunk support and better CMake support. Note that, other than possible security fixes, this is intended to be the final release of the 1.2 series.

• 13 August 2009 - libpng 1.2.39 is released with more minor updates to the build system, a public prototype for png_64bit_product(), and slightly stricter iCCP-write support. A .tar.xz package replaces the .tar.lzma package on SourceForge and the .tar.bz2 link here.

• 16 July 2009 - libpng 1.2.38 is released with minor updates to the build system and unknown-chunk support.

• 4 June 2009 - libpng 1.2.37 is released with a fix for 1.2.36's fix for a small (7-bit) uninitialized-memory read, plus various documentation, example.c, and cosmetic fixes.

• 7 May 2009 - libpng 1.2.36 is released (but not announced...) with a fix for a small (7-bit) uninitialized-memory read, a possible memory leak when writing the iCCP (ICC profile) chunk, and some other minor fixes.

• 18 February 2009 - libpng 1.2.35 is released with a fix for a longstanding uninitialized-data bug involving arrays of pointers (CVE-2009-0040).
