News and History of the PNG Development Group from 2017
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
- 16 March 2017 - libpng 1.6.29 is
released with new PowerPC optimizations, and it moves the SSE2 code into
the main distribution.
- 15 January 2017 - zlib 1.2.11
is released with fixes for "a bug and an issue" in 1.2.10. Note that there
are reports that while the 32-bit x86 assembler code works fine, the 64-bit
version does not work on Windows (size of long differs from Linux), and
it's unclear whether it works entirely correctly even on Linux. Only the C
code is officially supported.
- 5 January 2017 - libpng 1.6.28 is
released with a workaround for a bug exposed by building with the new
versions of zlib.
- 2 January 2017 - zlib 1.2.10
is released with fixes for two serious bugs in 1.2.9. (Oops.)
- 1 January 2017 - zlib 1.2.9
