Maintaining change logs

(for committers)

When committing a feature change, make sure to mention it on the changes page for the current release (which is part of the documentation of that release). Same holds for commits which involve backwards incompatible changes or changes that require special action when updating.

When committing a change which requires people to make database changes, configuration changes or some other changes to their setup, please add them to this page on the community wiki (besides notifying the mailing list of course).
