Activities

TC39 (previously: TC39-TG1) has made public a reference implementation of the proposed ECMA-262 4th edition language and is continuing to refine that implementation based on public and internal feedback (see the ECMAScript Programming Language website). A wiki for editing the ECMAScript Edition 4 spec has been set up and most of it is public.

A majority of the previous TC39-TG1 has finalised the set of proposals for edition 4, produced a reference implementation of the language, created a system for tracking design issues, and published an overview of the language.

The TC39 majority is currently writing the text of the 4th edition of ECMA-262 and plans to produce a final draft for approval at the December 2008 General Assembly.

A minority group of TC39 is working on a proposal for the maintenance of edition 3, and does not support the majority's proposal for edition 4.
