Sources and pins

Update this page whenever an initiative re-pins an upstream. Inventories and matrices should be reconciled in the same change set.

​

ECMAScript (I1)

Not the pin: the living draft at tc39.es/ecma262 tracks work after the yearly snapshot. Do not use it as the claimed edition URL until an explicit re-pin.

​

Re-pin checklist (new ECMA edition)

1. Record new edition name + stable HTML URL (edition snapshot, not only the living draft root) + catalog/PDF if available
2. Bump Test262 SHA to a matching suite revision
3. Diff feature matrix and built-ins
4. Open engineering Linear issues for deltas
5. Update scripty docs/es-pin.md and docs/matrix/language.md in the same change set
6. Do not claim the new edition in release notes until in-scope matrix rows catch up
