Adobe announced today that it will be contributing source code from the ActionScript Virtual Machine 2 (the ActionScript 3.0 Flash Player Scripting Engine introduced with Flash Player 9) to a new open source project, called Tamarin.

The Tamarin virtual machine will be implementing the final version of the ECMAScript Edition 4 (ES4) language specification.

In addition to driving the Adobe ActionScript Virtual Machine in Flash Player, Tamarin will be used in the next generation of SpiderMonkey, the core JavaScript engine in Firefox.
