News and History of the MNG Developers from 2000
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
- 28 December 2000 - Voting on elevating version 0.995 of the MNG
spec to 1.0 status begins...
- 25 December 2000 - Version 0.995 of the MNG spec is
released. It incorporates an approved change to the meaning of the
FRAM chunk's timeout value (for consistency with other timeout values),
and it includes a new section on registration of new chunks and
extensions. This is the final version before the big vote!
- 11 December 2000 - Version 0.99 of the MNG spec is
released. This version incorporates a number of final clarifications
and consistency fixes that were recently approved, and it adds one new
filtering method (intrapixel differencing, also formally approved) that
can result in 10% improvement in compression of truecolor images.
- 5 November 2000 - Draft 71 (version 0.98) of the MNG spec is
released. It includes new JDAA (JPEG alpha channel) and MAGN
("magnification," e.g., of a thumbnail-sized image to full size)
chunks, defines some new bits in the complexity profile, and clarifies
quite a number of small ambiguities. (Most of the changes were formally
approved by the MNG group in September.) Next stop: version 1.0!
- 29 October 2000 - libmng 0.9.3 is released. It adds support for
the new JDAA (JNG alpha) and MAGN chunks, includes some new sample apps,
and fixes various things.
- 26 October 2000 - Hung Lam reports that the current PC World
Vietnam has an article on (or at least a mention of) MNG.

Desktop Environment for Linux and other X systems, is released with
MNG support included.

- 6 September 2000 - Casey
Shobe reports that Konqueror
now supports inlined MNGs if it is compiled with a version of Qt 2.2.0
that has, in turn, been compiled with libmng. That makes it the second browser to support MNG

bugs, includes the latest version of Jason Summers' plug-in, and adds

is released. It adds improved support for suspend/resume functions,
better documentation, and fixes a couple of bugs reported in the first
- 8 July 2000 - MNG support in Mozilla is turned on by default.
Grab a recent nightly build and let 'er rip! (Greg did...whoa, gnarly.)
- 4 July 2000 - Warwick
Allison releases the first Netscape MNG plug-in for Linux, based
on libmng-based MNG code in an upcoming Qt release.
(Greg can attest that it works mighty darned fine!) Moreover, new
MNG-supporting apps from Ralph
Furumizo, and others have recently been released.
- 30 June 2000 - libmng 0.9.0, the first official beta version, is

- 23 May 2000 - The June 2000 issue of C Magazine, a Japanese
print publication by SoftBank Publishing, includes a four-part, 25-page
article on MNG. According to Glenn, Part 1 is an intro and comparison of
MNG vs. GIF; Part 2 describes the MNG chunk layouts; Part 3 describes a
MNG plug-in for the Pmacs
image editor; and Part 4 is a fairly complete Japanese translation of
version 0.97 of the MNG-LC spec.
- 16 May 2000 - libmng 0.5.1 is released. This version has "all
the chunk functionality in place and functioning (read, examine, create
and write)." It even includes a Netscape plug-in (for
Windows) by Jason Summers.
- 3 May 2000 - The MNG home site moves for what should be the last
time, thanks to a new libpng.org domain (not libmng.org!)
that can be redirected at will if the underlying host site should ever
change again. The new URLs are:
For now, the http and ftp sites are hosted on the same machine, so the
content is identical. (Note that the PNG and zlib home sites also
- 1 May 2000 - Gerard Juyn releases the first alpha version of
