New ECMAScript version numbering scheme

Per a post today on the es-discuss mailing list, the next version of the JavaScript standard will be ECMAScript 5. This version was previously called ECMAScript 3.1, and is a relatively small and long-overdue update to the language. Version 4 of the standard has been in the planning stages for 10 years or more, but those plans have been scrapped. To avoid confusion, with those old plans, however, there will be no version 4 of the standard.
