+
+### **Explicit Resource Management reaches stage 4** (5adf344)
+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** (7e2d9a4)
+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** (aa5330f)
+`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** (2af05ca)
+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** (cd2396f)
+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** (2b91377)
+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** (217882a)
+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+### **isTemplateObject withdrawn** (e605e9b)
+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

+
+### **Iterator Join reaches Stage 3** (805ff12)
+TC39 advanced Iterator Join to Stage 3 in the main proposals list, marking it as one of the more mature iterator additions on the docket. That typically signals the proposal is nearing standardization and is ready for deeper implementation feedback.
+
+### **Iterator Includes reaches Stage 3** (88dc035)
+Iterator Includes was also promoted to Stage 3. Like the other iterator updates, this is a meaningful maturity jump that reflects committee confidence in the proposal’s direction.
+
+### **Iterator chunking reaches Stage 3** (7226f0a)
+Iterator chunking was moved into Stage 3 as well. The commit updates the active proposals listing, indicating the feature has progressed beyond early design discussion.
+
+### **Amount moves up to Stage 2** (c310990)
+Amount was promoted from Stage 1 to Stage 2, which is a notable step toward implementation and experimentation. The proposal was removed from the Stage 1 list and added to the Stage 2 tracking table.
+
+### **New and updated Intl proposals land in ECMA-402** (6e24aea, e16c6d2, 37b5fe4)
+ECMA-402 gained two new Stage 1 entries: Intl Sequence Units and Default Behaviours for some Intl APIs, and Stable Formatting was moved up to Stage 2. The Stable Formatting update is the most significant here, since it reflects a higher level of committee agreement and moves the proposal into the more advanced tracking set.
+
+### **Other misc changes**
+- Added the Stage 1 entry for "export all from" (3836466)
+- Minor proposal-list reordering and link updates
