Changelog

Enhancements

Things you added that don't break anything. Regression tests for Bug Fixes count as Enhancements.

Bug Fixes

Things you changed that fix bugs. If a fixes a bug, but in so doing adds a new requirement, removes code, or requires a database reset and reindex, the breaking part of the change should be added to Incompatible Changes below also.

Incompatible Changes

Things you broke while doing Enhancements and Bug Fixes. Breaking changes include (1) adding new requirements and (2) removing code. Renaming counts as (2) because a rename is a removal followed by an add.

Upgrading

If you have any Incompatible Changes in the above Changelog, outline how users of prior versions can upgrade once this PR lands or when reviewers are testing locally. A common upgrading step is "Database reset and re-index required".
