We are THRILLED to announce that our Ecma standards will now use UUIDs instead of integers. ECMA-262 is now ECMA-39c506d7-731f-4220-8ffd-a68970945a65. Far more scalable. No two specs will ever collide again. Perfect system. Shortened forms like ECMA-39c506d7 are acceptable in casual conversation.

A back-compat alias may be provided for a short deprecation period as a courtesy. You're welcome.

ECMAScript Excitement 🎉 This week, TC39 elected a new editor group for the ECMAScript specification (ECMA-262). Editors are: ✨ Linus Groh ✨ Michael Ficarra ✨ Nicolò Ribaudo (@nicr.dev) ✨ Richard Gibson ✨ Ron Buckton (@chronicles.org) ✨ Shu-yu Guo (@rfrn.org)

We're grateful to Michael and Shu for continuing and excited to welcome Linus, Nicolò, Richard, and Ron. Many thanks to Kevin Gibbons (@bakkot.com) for his years of service as an editor; we look forward to his continued participation in committee.
