Adobe has opened the source code of the ActionScript Virtual Machine, the high-performance ECMAScript implementation used in Adobe’s ubiquitous Flash Player. Adobe has made the source code available under three prominent open source licenses, and contributed it to Mozilla for eventual inclusion in Firefox.
Mozilla developers hope to integrate Tamarin into Firefox in 2008. Source code is already available in the Mozilla CVS, and independent open source developers are encouraged to participate. More information is available from the Tamarin FAQ and on the Tamarin mailing list.
