Version Release

Version Release Workflow

Overview

The primary development branch is canary. All day-to-day development happens on canary. When releasing, canary is merged into main. After merge, auto-tag-release.yml automatically handles tagging, version bumping, creating a GitHub Release, and syncing back to the canary branch.

Only two release types are used in practice (major releases are extremely rare and can be ignored):

Minor Release Workflow

Used to publish a new minor version (e.g. v2.2.0), roughly every 4 weeks.

Steps

1. Create a release branch from canary

git checkout canary
git pull origin canary
git checkout -b release/v{version}
git push -u origin release/v{version}

2. Determine the version number — Read the current version from package.json and compute the next minor version (e.g. 2.1.x → 2.2.0)

3. Create a PR to main

gh pr create \
  --title "🚀 release: v{version}" \
  --base main \
  --head release/v{version} \
  --body "## 📦 Release v{version} ..."

[!IMPORTANT]: The PR title must strictly match the 🚀 release: v{x.y.z} format. CI uses a regex on this title to determine the exact version number.

4. Automatic trigger after merge: auto-tag-release detects the title format and uses the version number from the title to complete the release.

Scripts

bun run release:branch         # Interactive
bun run release:branch --minor # Directly specify minor

Patch Release Workflow

Version number is automatically bumped by patch +1. There are 4 common scenarios:

All scenarios auto-bump patch +1. Patch PR titles do not need a version number. See reference/patch-release-scenarios.md for detailed steps per scenario.

Scripts

bun run hotfix:branch # Hotfix scenario

Auto-Release Trigger Rules (auto-tag-release.yml)

After a PR is merged into main, CI determines whether to release based on the following priority:

1. Minor Release (Exact Version)

PR title matches 🚀 release: v{x.y.z} → uses the version number from the title.

2. Patch Release (Auto patch +1)

Triggered by the following priority:

• Branch name match: hotfix/* or release/* → triggers directly (skips title detection)
• Title prefix match: PRs with the following title prefixes will trigger:
  • style / 💄 style
  • feat / ✨ feat
  • fix / 🐛 fix
  • refactor / ♻️ refactor
  • hotfix / 🐛 hotfix / 🩹 hotfix
  • build / 👷 build

3. No Trigger

PRs that don't match any of the above conditions (e.g. docs, chore, ci, test prefixes) will not trigger a release when merged into main.

Post-Release Automated Actions

1. Bump package.json — commits 🔖 chore(release): release version v{x.y.z} [skip ci]
2. Create annotated tag — v{x.y.z}
3. Create GitHub Release
4. Dispatch sync-main-to-canary — syncs main back to the canary branch

Claude Action Guide

When the user requests a release:

Minor Release

1. Read package.json to get the current version and compute the next minor version
2. Create a release/v{version} branch from canary
3. Push and create a PR — title must be 🚀 release: v{version}
4. Inform the user that merging the PR will automatically trigger the release

Precheck

Before creating the release branch, verify the source branch:

• Weekly Release (release/weekly-*): must branch from canary
• All other release/hotfix branches: must branch from main — run git merge-base --is-ancestor main <branch> && echo OK to confirm
• If the branch is based on the wrong source, delete and recreate from the correct base

Patch Release

Choose the appropriate workflow based on the scenario (see reference/patch-release-scenarios.md):

• Weekly Release: Create a release/weekly-{YYYYMMDD} branch from canary, scan git log main..canary to write the changelog, title like 🚀 release: 20260222
• Bug Hotfix: Create a hotfix/ branch from main, use a gitmoji prefix title (e.g. 🐛 fix: ...)
• New Model Launch: Community PRs trigger automatically via title prefix (feat / style), no extra steps needed
• DB Migration: Create a release/db-migration-{name} branch from main, cherry-pick migration commits, write a dedicated migration changelog

Important Notes

• Do NOT manually modify the version in package.json — CI will auto-bump it
• Do NOT manually create tags — CI will create them automatically
• The Minor Release PR title format is a hard requirement — incorrect format will not use the specified version number
• Patch PRs do not need a version number — CI auto-bumps patch +1
• All release PRs must include a user-facing changelog

Changelog Writing Guidelines

All release PR bodies (both Minor and Patch) must include a user-facing changelog. Scan changes via git log main..canary --oneline or git diff main...canary --stat, then write following the format below.

Format Reference

• Weekly Release: See reference/changelog-example/weekly-release.md
• DB Migration: See reference/changelog-example/db-migration.md

Writing Tips

• User-facing: Describe changes that users can perceive, not internal implementation details
• Clear categories: Group by features, models/providers, desktop, stability/fixes, etc.
• Highlight key items: Use **bold** for important feature names
• Credit contributors: Collect all committers via git log and list alphabetically
• Flexible categories: Choose categories based on actual changes — no need to force-fit all categories
