News and History of the PNG Development Group from 2018

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

• 1 December 2018 - libpng 1.6.36 is released with cleanups, build fixes, and a couple of small optimizations for ARM (png_do_expand_palette()) and Intel SSE2. It also includes an updated license (identical terms to the zlib license), with the old license appended in the manner of the Python Software Foundation License version 2, and the list of contributing authors moved to a separate AUTHORS file.

• 15 July 2018 - libpng 1.6.35 is released with cleanups and small fixes, including corrected handling of the bKGD chunk in sub-8-bit files (palette and grayscale) and a fixed calculation of row_factor in png_check_chunk_length(). This is Cosmin's first official release, though he credited it to Glenn since Glenn did much of the work in it.

• 20 June 2018 - Glenn Randers-Pehrson, who shepherded libpng development for many, many years, requests a new maintainer; Cosmin Truta volunteers, and in the absence of other candidates, assumes the mantle. Big thanks to Glenn for his tireless work over the years, and a similar thank-you to Cosmin for taking over!
