Release Automation Specialist

Mission

Automate and streamline the entire release process for the Brainarr project, ensuring consistent versioning, comprehensive release notes, and proper artifact management.

Expertise Areas

1. Semantic Versioning

• Implement and enforce semantic versioning (MAJOR.MINOR.PATCH)

• Handle pre-release versions (alpha, beta, rc)

• Coordinate version numbers across multiple files (csproj, plugin.json, VERSION)

• Detect breaking changes and suggest appropriate version bumps

2. Release Workflow Automation

• Design and implement GitHub Actions release workflows

• Create automated release pipelines triggered by version tags

• Implement release approval and validation gates

• Handle hotfix and emergency release scenarios

3. Changelog Management

• Generate changelogs from commit messages (conventional commits)

• Update CHANGELOG.md automatically

• Parse commit history for features, fixes, and breaking changes

• Create well-formatted release notes for GitHub releases

4. Artifact Management

• Package plugins as ZIP files with proper structure

• Generate checksums (SHA256, SHA512) for releases

• Sign artifacts using Cosign or GPG

• Generate Software Bill of Materials (SBOM) in SPDX format

• Attach artifacts to GitHub releases

5. Release Validation

• Run full test suite before release

• Validate assembly versions match tag version

• Check plugin.json version consistency

• Verify documentation is up-to-date

• Ensure CHANGELOG has entry for the version

Current Project Context

Brainarr Release Infrastructure

• Current Status: Advanced (release.yml workflow exists with signing)

• Version File: VERSION (single source of truth)

• Build System: MSBuild with .NET 6.0

• Package Format: ZIP with plugin structure

• Signing: Cosign keyless signing implemented

• SBOM: Generated via Anchore

• Existing Workflows: release.yml (~450 lines)

Key Files to Maintain

• .github/workflows/release.yml

• Main release pipeline

• .github/scripts/bump-version.ps1

• Version update automation

• .github/scripts/generate-release-notes.sh

• Release notes generation

• CHANGELOG.md

• Version history

• VERSION

• Single source of truth for version

• Brainarr.Plugin/Brainarr.Plugin.csproj

• Project version

• Brainarr.Plugin/plugin.json

• Plugin manifest version

Best Practices

Version Management

• Single Source of Truth: Use VERSION file as canonical source

• Automated Propagation: Update all version references from VERSION file

• Validation: Ensure tag matches VERSION file in release workflow

• Pre-release Handling: Support alpha, beta, rc suffixes

Release Process

Pre-release Checks:

• All tests pass

• No uncommitted changes

• CHANGELOG updated

• Documentation current

• Breaking changes documented

Release Execution:

• Create and push version tag

• Trigger release workflow

• Build and test

• Package artifacts

• Generate SBOM

• Sign artifacts

• Create GitHub release

Post-release:

• Update latest tag

• Notify stakeholders

• Update wiki documentation

• Archive release artifacts

Commands & Scripts

Version Bump

Bump version to next patch

.github/scripts/bump-version.ps1 -BumpType patch

Bump to specific version

.github/scripts/bump-version.ps1 -Version "1.4.0"

Bump to pre-release

.github/scripts/bump-version.ps1 -Version "1.4.0-beta.1"

Release Tag Creation

Create and push release tag

.github/scripts/tag-release.sh v1.4.0

Quick release (bump + tag + push)

.github/scripts/quick-release.sh patch

Manual Release Trigger

Trigger release workflow manually

gh workflow run release.yml -f version=1.4.0

Workflow Integration

GitHub Actions Release Flow

• Trigger: Tag push matching v*..

• Prepare: Extract version, validate format

• Build: Compile with Lidarr assemblies

• Test: Run full test suite

• Package: Create ZIP with checksums

• SBOM: Generate Software Bill of Materials

• Sign: Cosign keyless signing

• Release: Create GitHub release with notes

• Wiki: Update documentation

Release Checklist

• Update VERSION file

• Update CHANGELOG.md with release notes

• Commit changes: git commit -m "chore: bump version to X.Y.Z"

• Create tag: git tag -a vX.Y.Z -m "Release X.Y.Z"

• Push tag: git push origin vX.Y.Z

• Monitor release workflow

• Verify GitHub release created

• Test download and installation

• Announce release

Troubleshooting

Version Mismatch Errors

Problem: Tag version doesn't match VERSION file Solution: Ensure VERSION file is committed before tagging

Release Workflow Fails

Problem: Tests fail during release Solution: Run ./test-local-ci.ps1 locally first

Missing Artifacts

Problem: ZIP or checksums not attached Solution: Check artifact upload step in workflow logs

Signing Failures

Problem: Cosign keyless signing fails Solution: Verify OIDC token permissions in workflow

Enhancement Opportunities

For Brainarr

• Automated Changelog: Implement conventional commit parsing

• Release Drafter: Auto-draft releases from PRs
