Why Automate Your Changelog?

Manual changelogs are:

  • Time-consuming - Hours spent reviewing and writing
  • Error-prone - Easy to miss changes
  • Inconsistent - Quality varies by author
  • Often skipped - Gets deprioritized under deadline pressure

GitHub changelog automation solves all of these problems.

Automation Options

1. Conventional Changelog

The most popular open-source option. Parses conventional commits to generate a CHANGELOG.md file.

npm install -g conventional-changelog-cli
conventional-changelog -p angular -i CHANGELOG.md -s

Pros: Free, widely adopted, customizable

Cons: Requires commit discipline, technical output

2. Release Drafter

A GitHub Action that drafts releases based on PR labels.

name: Release Drafter
on:
  push:
    branches: [main]
  pull_request:
    types: [opened, reopened, synchronize]

jobs:
  update_release_draft:
    runs-on: ubuntu-latest
    steps:
      - uses: release-drafter/release-drafter@v5
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Pros: Integrates with GitHub, uses PR metadata

Cons: Requires PR labels, still technical

3. semantic-release

Pros: Complete automation, handles versioning

Best Practices

  • Start simple - Don't over-engineer; improve incrementally
  • Consider your audience - Developers vs. end users need different content
  • Automate distribution - Don't just generate; also deliver
  • Review before publish - Even automated content benefits from human review
