v2.2.1

Allow absolute paths in addition to valid URLs as landingpage- and promotion targets. This already worked before, so the schema was relaxed to match reality.

v2.2.0

Introduce type attribute to filter value frequency with possible values absolute and additive to indicate whether the frequency value is the absolute number of matches once this filter is selected, or the additional number of results after selection.
