Essentially, we have to cater for two types of release:

1. release changes from (development) trunk to a brand new series; and,
2. cherry-picking from (development) trunk to an existing series (or,
very occasionally fixing on the series directly)

In theory, there should be a third one: releasing changes from
development to the current series - but our server ABI isn't
sufficiently stable to do that.
