Looking at the major browser vendors, one sees the same pattern. Opera and Mozilla have moved their implementations closer to the ECMAScript and related CSS/DOM standards, while Microsoft has frozen its browser since its last update in 2002. Currently, ECMAScript version 4 was due to be approved and published by 1Q 2004. But that hasn’t happened and is likely to be delayed by 6-12 months as new players come on board at the ECMAScript steering committee.
