News and History of the MNG Developers from 2003

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

• 17 November 2003 - zlib 1.2.1 is released. This version improves the speed of inflate by 20% and that of the CRC by 50%, adds a new Z_RLE strategy (especially for PNG/MNG!), fixes some memory leaks and other bugs, improves and updates the documentation, improves portability (of builds), adds some new contrib material, updates the Win32 DLL interface (note: it is binary-incompatible with previous versions), etc. In addition, co-author Mark Adler has now taken over as the principal maintainer of zlib, although Jean-loup still maintains the web site.

• 12 June 2003 - Mozilla's restore MNG support bug passes the 400-vote mark, making it currently the browser's most voted-for outstanding bug (i.e., to be fixed), and possibly the most voted-for Mozilla bug ever. (Note that mng-list has fewer than a quarter that many subscribers, and voters must be registered with the Bugzilla system, so it's not a matter of ballot-stuffing.) Most impressive. The user community has spoken!

• 3 June 2003 - Tim "tor" Rowley and Stuart "pavlov" Parmenter remove MNG support from Mozilla for not very well understood reasons. (That is, the reasons presented in the bug report were all refuted to greater or lesser extent, but MNG was removed--not even just disabled--anyway.) The user community is not amused.

• 1 March 2003 - libmng 1.0.5 is released. This is a maintenance release that fixes a buffer overflow, adds support for streaming MNGs (ability to turn caching off), and achieves nearly full MNG compliance. It also supports the final-interframe-delay clarification (see previous news item) that was one of the two main changes in the MNG 1.1 spec.
