The next minor descends from the preceding mainline, rather than its release branch. The 0.83 release line is separate. Documentation #3038 branches from #3037.

Merge and release order

This tracker records the intended order for React Native macOS 0.83–0.87. Checkboxes indicate merged PRs.
All active implementation PRs are open. The 0.87 portion now follows one first-parent path.

Loading

Reusable features precede stable-release preparation. The topology-only final release tree was byte-identical to the original candidate; separately reviewed and validated CI repairs are now included. Stable releases #3022, #3031, #3034, and #3036 keep their earlier separate release branches and checkpoints.

Consolidated header reviews: #3102 and #3103 are closed as superseded by #3105. Their complete implementations remain included; the original branches and review history are preserved.

Documentation

• docs: add minor merge and release skill #3038 — Document the minor merge and release process. Depends on the 0.87 merge branch.

Validation and follow-up

The reviewed repair packet passed 1,406 release-helper tests across the 18 active heads. Both changed linear RC checkpoints passed separate immutable installs, constraints, graph, packing, and helper checks. All 27 active remote destinations and same-remote backups were verified under backup/pre-ci-repair-20260922/<original-branch>. Final current-head CI acceptance is recorded below.

Local release validation includes five exact-peer clean consumers, 56 consumer checks, ten verified tarball hashes, and five read-only publication previews.
Native and API validation retains its recorded source-tree scope; it does not imply that every build ran at every final commit.

The 2026-09-21 synchronization verified 24 remote destinations and 15 same-repository backups.
Backup branches use backup/pre-release-sync-20260921-1447/<original-branch>.

• Correct public-registry lock metadata. All 18 hosted generation/immutable/constraints/audit jobs passed in run 35769816507. The independently reviewed correction contains only 792 equivalent executable-path prefix changes; dependency versions, checksums, ranges, source files, and the linear stack are unchanged. All 27 updated destinations and their backup/pre-public-registry-20260922/… backups are verified.
• Clear GitHub's stale conflict reports for chore(0.84): prepare stable 0.84.0 with React Native 0.84.1 #3031, chore(0.85): prepare stable 0.85.0 with React Native 0.85.3 #3034, feat: merge 0.86-merge into 0.85-merge #3035, and docs: add minor merge and release skill #3038. All four report mergeable after a base refresh; original bases and heads were preserved.
• Post current-source replies to all six older chore(0.83): prepare stable 0.83.0 with React Native 0.83.10 #3022 review threads (Changesets base, version export, test-app/init forward-ports, frame observer scope, and DevLoadingView applicability). Reviewer resolution/approval remains pending.
• Complete current-head CI acceptance for all 18 active PRs.
• Reviewer/owner: resolve remaining review threads and approve the submitted heads before merging.
• Owner: configure the GitHub npm-publish environment and confirm both npm Trusted Publisher configurations. A fresh environment query still lists only copilot and github-pages.

These CI observations describe the initial post-push snapshot. Each PR's current Checks tab remains authoritative.

Completed CI follow-up

• The independently reviewed follow-up is committed and pushed: 16 heads / 25 destinations, with same-repository backups under backup/pre-ci-followup-20260922/<original-branch>.
• The combined packet passed 92 validation commands, including 12 API revalidations/generated TypeScript checks, full formatting checks, and 124 targeted suites / 3,076 tests.
• Corrections include generated API snapshots, branch-specific Hermes fixtures, deterministic generation of the eight native-spec headers used by the inventory test, scoped formatting, feat(0.87): add focused Apple header and SwiftPM foundations #3104's sidecar copy, and feat: merge 0.85-merge into 0.84-merge #3033's destination guards. Public-registry locks and package manifests remain exact.
• Stable 0.85/0.86 retain their already-passing source trees; new commits preserve corrected predecessor ancestry. Main fix(macos): forward-port shared release fixes to main #3099 and stable 0.83 chore(0.83): prepare stable 0.83.0 with React Native 0.83.10 #3022 remain at their green heads.
• fix(interop): preserve the legacy view manager removal guard #3106's one job-specific CMake retry passed the actual iOS-dynamic RNTester build.
• All six older chore(0.83): prepare stable 0.83.0 with React Native 0.83.10 #3022 review threads now have current-source replies. Reviewer resolution and approval remain owner-controlled.

Current release heads: 0.83 88195ce7d609, 0.84 959a063f7bfa, 0.85 5162d0eab630, 0.86 33dc11c33805, 0.87 1a9971c257ba.

The subsequent Flow/lint correction is also committed and pushed: five source repairs and three tree-identical ancestry caps, with all 14 destinations and backup/pre-flow-lint-20260922/… backups verified. Full Flow, ESLint, and formatting passed; API declarations, generated outputs, package versions and locks are preserved.

Fresh CI acceptance is complete for all 18 recorded heads. No PR merges or npm publications have occurred.

Final technical acceptance

All 18 expected current-head CI check sets passed at 2026-09-23 02:34:29 UTC, with no failed or pending checks in the completed observer snapshot. Source corrections, generated snapshots, fixture/format repairs, public-registry metadata, review replies, guarded pushes, and the linear jj/PR stack are complete.

The remaining steps are owner/reviewer actions: review resolution and approval, merge in order, configure/verify npm-publish and both npm Trusted Publishers, publish 0.83.0 through 0.87.0 in order, then verify each published release before continuing. No PR merges or npm publication have been performed by this task.

Release rules

• Merge the shared fixes into main before the upgrade PRs.
• Retarget dependent PRs as their predecessors merge.
• Keep release branches separate from the next minor's mainline ancestry.
• Publish 0.83.0 → 0.84.0 → 0.85.0 → 0.86.0 → 0.87.0.
• Verify each publication before the next release.
• Use Changesets and GitHub trusted publishing. Publish virtualized-lists before core, with exactly one dist-tag per package upload.
• Recalculate tags from the current registry state. Skip already-published versions without tag mutation.
