 Pull requests should be made against the `develop` branch. Any backports
 necessary will be handled by the development team.
+
+New features and bug fixes are usually worth mentioning in the changelog.
+Exceptions are fixes for bugs that never shipped (were only present in a canary
+build), and changes with no intended user observable behavior, such as a
+refactor. If you're comfortable writing the note yourself, add it to
+`changelog.md` in the root of the project in the section for the upcoming
+release.
