This document is intended for users of the applications and API. Changes to things
like tests should not be noted in this document.

When updating this file for a PR, add an entry for your change under Unreleased
and one of the following headings:
 - Added - for new features.
 - Changed - for changes in existing functionality.
 - Deprecated - for soon-to-be removed features.
 - Removed - for now removed features.
 - Fixed - for any bug fixes.
 - Security - in case of vulnerabilities.

If the heading does not yet exist under Unreleased, then add it as a 3rd heading,
with three #.


When preparing for a public release candidate add a new 2nd heading, with two #, under
Unreleased with the version number and the release date, in year-month-day
format. Then, add a link for the new version at the bottom of this document and
update the Unreleased link so that it compares against the latest release tag.


When preparing for a bug fix release create a new 2nd heading above the Fixed
heading to indicate that only the bug fixes and security fixes are in the bug fix
release.
