News and History of the MNG Developers from 2001

Herein lie news items and historical stuff regarding MNG. Feel free to poke around, but note that some of the links, particularly the older ones, may be broken. Keep in mind that this is history here...

• latest - see here

• 23 October 2001 - Stefan Mayrhofer sets up a web-based PNG/MNG-specific discussion area at http://pub33.ezboard.com/blibpng. It includes forums for software development, browsers, PNG web sites, MNG/JNG, and so forth.

• 18 September 2001 - libmng 1.0.3 is released. This version updates the Unix makefiles, include paths, and sample apps.

• 31 July 2001 - We're back! As many of you noticed, the most recent host site for libpng.org (FreeSoftware.com) has been pretty flaky since March or April, with no network connectivity for days or weeks at a time, and no ftp service whatsoever. So this weekend, Greg undertook to move the entire MNG site to a new host, SourceForge, and as of today, that move is mostly complete. Thanks to last year's foresight (see the 3 May 2000 news item) and SourceForge's most excellent virtual hosting, all of your old MNG and PNG links will once again work automagically:
  • http://www.libpng.org/pub/mng/
  • http://www.libpng.org/pub/png/
  Well...almost. Greg still has to figure out what's up with ftp access, which is important for mirroring, but we're close... SourceForge also supports rsync, but Greg doesn't know much about that yet, either.

• 7 July 2001 - libmng 1.0.2 is released. This version adds an option that allows apps to optimize the memory usage of long, video-like MNG streams (i.e., those with no looping), and another option that turns off progressive display of large images.

• 2 May 2001 - libmng 1.0.1 is released. This version fixes some memory leaks and minor bugs, and it simplifies the use of the color-management system on sRGB systems.

• 6 February 2001 - And right on the heels of MNG 1.0 comes the release of libmng 1.0.0! Not only that, but it includes some contributed demo viewers for Linux/Unix and Windows, so there are no longer any excuses for not being able to view MNG animations. Go forth and animate in a patent-free manner!

• 31 January 2001 - Version 1.0 of the MNG spec is (finally!) released. This version has been proofread, formatted, and generally tweaked to look ever so beautiful in multiple formats, including PDF, PostScript, HTML (2.0 and 4.0), and plain ASCII text.

• 19 January 2001 - libmng 0.9.4, the "final release candidate for libmng 1.0," is released. It improves support for MAGN and filter-method 64, and it fixes some minor things.

• 16 January 2001 - Cosmin Truta releases a first cut at an EBNF grammar for PNG, MNG and JNG. (That would be an "Extended Backus-Naur Form," for those of us who are somewhat less clue-enhanced.)

• 11 January 2001 - Voting on the MNG spec closes; MNG 1.0 is approved! Break out the leftover whizzy things from New Year's Eve, and party on...

• 10 January 2001 - Version 0.997 of the MNG spec is released. As with its predecessor, its only changes are editorial (formatting, grammar).

• 3 January 2001 - Version 0.996 of the MNG spec is released. Its only changes are editorial (expanded intro section and corrected typos).
