Add an entry to the changelog

Please don't forget to update CHANGELOG.md and describe your changes (in the "unreleased" section), this makes the release of a new bat version much easier.

Each entry should follow the following format:

- Short description of what has been changed, see #123 (@user)

Where #123 is your PR's number or ticket and @user is you Github's username.
