In a new post to his site Tomas Votruba talks about how to use Simplify to generate a changelog for your project's updates and output it into a CHANGELOG.md file.

ChangelogLinker started as a small tool to complete links to PRs, authors, and versions in CHANGELOG.md. Then it started to generate the CHANGELOG.md.

Where is now and how to start using it?

He starts by showing how to install the package via Composer and how to use it for:

• Multiple CHANGELOG.md for Smaller Versions
• [using] Smarter Last Change Detection
• Removing Dead Links
• Improved Category Detection

The last one is quite handy as it gives more context to the items in the resulting Changelog rather than just a list of commits.
