 - Changed - for changes in existing functionality.
 - Deprecated - for soon-to-be removed features.
 - Removed - for now removed features.
 - Fixed - for any bug fixes.

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
