No issue — this came out of asking why 1.2.0 went straight to 2.0.0.

Problem

Changesets keeps one ci: release packages pull request open on main and rewrites it as changesets land. Merging it cuts exactly one release, so how often it is merged is what decides the version sequence — and nothing said how often that should be.

Left to accumulate, it collapses a backlog into one bump. The current release pull request carries 19 changesets, all from a single squashed pull request: one major, four minor, fourteen patch. They become one version, 2.0.0, and every number in between never exists. The changelog cannot attribute anything either, because every entry cites the same commit.

What changed

A repository variable, AUTO_MERGE_RELEASE_PR, picks the cadence:

  • true — the release pull request merges itself once its required checks pass. One merge to main is one release, and the version tracks each change: 2.1.2, 2.1.3, 2.1.4, 2.2.0.
  • unset or false — today's behaviour, unchanged. A maintainer merges it when a release is wanted.

This is deliberately not a blanket auto-merge:

  • it only ever targets the changesets-authored changeset-release/main branch,
  • the repository's ten required status checks still gate the merge (strict: true, so the branch must be current),
  • and a major is gated separately, on the pull request that introduces the changeset — so an unattended release can never rename the major version on its own.

The step is continue-on-error. A version pull request left open costs a manual merge; a failure here would block npm, the Marketplace and the CDN behind it.

CONTRIBUTING.md now states the bump levels and both cadences, so the version sequence is a documented choice rather than a side effect of merge timing.

Not included

Tagging is already correct and needed no change — releases are tagged @pymodel/pythinker-code@<version> with a matching GitHub Release, and the desktop app cuts desktop-v* separately.

[skip changeset] — release tooling and contributor docs only; nothing here reaches the published package.

Checklist

  • I have read the CONTRIBUTING document.
  • I have linked a related issue (external PRs: the issue must have a maintainer's /approve).
  • I have added tests that prove my feature works.
  • Ran gen-changesets skill, or this PR needs no changeset.
  • Ran gen-docs skill, or this PR needs no doc update.

Summary by CodeRabbit

  • New Features

    • Added optional automatic squash-merging for release pull requests when enabled.
    • Improved release workflows by reliably identifying the correct release pull request for review and merging.
    • Release workflow lookup issues remain non-blocking when a matching pull request is unavailable.
  • Documentation

    • Clarified one-changeset-per-PR guidance and approval requirements for major changes.
    • Documented that pinned installations remain functional until consumers upgrade.
    • Explained how changesets added during release checks are included in the pending release.

Changesets keeps one release pull request open and rewrites it as changesets
land, so how often that pull request is merged is what decides the version
sequence. Left to accumulate it collapses a backlog into a single bump — which
is how nineteen changesets became one version and the numbers in between never
existed.

`AUTO_MERGE_RELEASE_PR` picks the cadence. Set to `true`, the release pull
request merges itself once its required checks pass, so one merge to main is
one release and the version tracks each change. Unset, nothing changes and a
maintainer merges it when a release is wanted.

This is not a blanket auto-merge: it only ever targets the changesets-authored
branch, the repository still requires its status checks, and a major bump is
gated on the pull request that introduces the changeset — so an unattended
release cannot rename the major version on its own. The step never fails the
run, because a version pull request left open costs a manual merge while a
failure here would block npm, the Marketplace and the CDN behind it.

CONTRIBUTING now states the bump levels and both cadences, so the version
sequence is a documented choice rather than a side effect of merge timing.

📝 Walkthrough

Walkthrough

The release workflow resolves a Changesets version PR once and reuses it for optional squash auto-merge and CodeRabbit review. The contribution guide clarifies changeset attribution, major-change approval, pinned-install behavior, and pending release handling.

Changes

Release cadence

Layer / File(s) Summary
Centralized release PR resolution
.github/workflows/release.yml
The workflow uses the Changesets-reported PR when available. Otherwise, it finds an open same-repository changeset-release/main PR targeting main. Auto-merge and CodeRabbit review use the resolved PR.
Changeset and cadence guidance
CONTRIBUTING.md
The guide clarifies one-changeset-per-PR attribution, approval for major changes, pinned-install behavior, and inclusion of changesets added while the release PR awaits checks.

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk: ⚪ Minimal · up to 5ece4

This PR adds opt-in cadence-based merging for the release pull request while preserving required checks and existing manual behavior; no actionable merge-blocking risk remains.

In @.github/workflows/release.yml:
- Around line 205-208: Update the pull-request lookup in the release workflow to
capture the exit status of gh pr list separately from its output instead of
masking failures with || true. If the command fails, emit a warning and exit
successfully; only report “No open version PR” when the command succeeds with an
empty or null pr result.
- Around line 198-210: Update the auto-merge flow around the “Enable auto-merge
on the version PR” step so later changesets cannot be added to an already queued
release PR, using a snapshot or release-queue guard; alternatively, explicitly
document that this workflow intentionally batches changesets. Preserve the
existing checks for published status, AUTO_MERGE_RELEASE_PR, and the
changeset-release/main PR.
- Around line 198-210: Update the “Enable auto-merge on the version PR” workflow
step to wait for a successful CodeRabbit status on the PR before invoking gh pr
merge --auto. Ensure the check targets the main branch context and preserves the
existing no-open-PR handling and merge command behavior.
- Around line 205-210: Update the release workflow to use
steps.changesets.outputs.pullRequestNumber as the version PR identifier for the
auto-merge and subsequent CodeRabbit steps, replacing the gh pr list lookup and
its related empty-result handling. Keep the existing merge behavior unchanged
for the identified PR.

In `@CONTRIBUTING.md`:
- Line 91: Update the changeset guidance in CONTRIBUTING.md to replace the
“several releases wearing one hat” idiom with direct wording: multiple
changesets in one pull request usually represent separate releases, and the
changelog cannot attribute them later.
- Line 93: Update the major-version description in the contributing guidance to
state that pinned installs remain on their existing version, while consumers
upgrading to the new major may encounter breaking changes; preserve the
surrounding maintainer approval and workflow requirements.
- Line 93: Update the major-release guidance in the contributing documentation
to match the repository’s actual workflow: remove the unsupported claims about
changeset-policy and breaking-change-approved, and replace the statement that
major releases break every pinned install with the accurate behavior that
exact-version installs remain on the previous version.

Both release steps found the pull request by head branch alone. That can
select a fork's branch of the same name, and `|| true` turned an API or
auth failure into "no version PR" — so a lookup that broke looked exactly
like a release with nothing to do.

Resolve it once instead: take the number the changesets action reports, and
fall back to a listing scoped to this repository's own head branch, keeping
a failed lookup distinct from an empty result. Auto-merge and the review
request both consume that number.

Also state in CONTRIBUTING that a changeset landing while the release pull
request waits on its checks joins that release, and correct the claim that
a major breaks pinned installs — it breaks consumers who upgrade.

Filtering the fallback lookup by head-repository owner still accepts a
different repository belonging to that owner. Compare the head repository's
full `owner/name` against `GITHUB_REPOSITORY` instead.
