README

Provides a script that generates a changelog based on titles of pull requests merged between specified references.

Is this the right tool for me?

Probably not. There are a range of other tools that probably do a better job.

Take a look at

• https://packagist.org/?q=changelog
• https://www.npmjs.com/search?q=changelog
• https://pypi.python.org/pypi?%3Aaction=search&term=changelog

Nonetheless, for me and my projects, it's the second best thing after manually keeping a changelog as suggested at http://keepachangelog.com.

When will it work for me?

My process	Will this tool work for me?
I need elaborate changelogs	No
I push directly into the default branch	No
	No
	No
	Yes

Why is this tool so limited?

All this tool does is this:

• it collects commits between references
• it matches commit messages against what is used by GitHub as a merge commit message
• it fetches the pull request title from the corresponding pull request
• it then uses all of the pull request titles to compile a list
