TC39 promotions and one withdrawal

Multiple proposals advanced, including two to stage 4, while isTemplateObject was withdrawn.

Explicit Resource Management reaches stage 4 (ljharb5adf344)

This proposal moved from the active list into finished proposals, marking it as standardized. The repo update also pruned its old README entry and moved its meeting-note links into the finished-proposals index.

Joint Iteration is now stage 4 (ljharb7e2d9a4)

Joint Iteration was added to the finished proposals table and removed from the active stage 3 list. That signals the proposal is complete and expected to ship on the ES2027 timeline shown in the table.

Atomics.pause reaches stage 4 (ljharbaa5330f)

Atomics.pause was promoted into finished proposals and removed from the active proposals page. The change also adds its canonical notes/link references to the finished list, reflecting its move into the standardization track.

Decorator Metadata advances to stage 2.7 (ljharb2af05ca)

Decorator Metadata was bumped to stage 2.7 in the main proposals list. This is a meaningful status change, but it is still an intermediate step rather than a final approval.

Decorators advances to stage 2.7 (ljharbcd2396f)

Decorators also moved to stage 2.7, keeping it aligned with the committee’s latest decision. This update reshuffles the active-stage tables rather than changing the proposal itself.

Intl Keep Trailing Zeros reaches stage 3 (ljharb2b91377)

The Intl proposal was promoted to stage 3 in the ECMA-402 tracker. Stage 3 indicates the committee expects the design to stabilize and implementation work to continue.

RegExp Buffer Boundaries moves to stage 2.7 (ljharb217882a)

RegExp Buffer Boundaries was updated to stage 2.7 in the active proposals list. It’s a small but notable status bump that shows the proposal is progressing.

isTemplateObject withdrawn (ljharbe605e9b)

The proposal was removed from the active list and added to inactive proposals with a withdrawal note citing lack of implementer interest and same-vs-cross-realm concerns. That’s a meaningful endpoint for the effort, even though it’s not a feature landing.

Other misc changes

  • Stage-table link/reference cleanup across README and finished-proposals
  • Proposal index reordering and table maintenance
