coll-sort
action, which can be used to sort a collection of events based on a field.
- Add
moving-time-window
action. This window always return the events which arrived the last duration
seconds.
- Add
ssort
action. This action buffers events for some time and send them one by one sorted to downstream actions. It can be a nice way to tolerate some late events in streams.

values in conditions. For example [:and [:or [:= :service "foo"] [:= :service "bar"]] [:> :metric 1]]
is now a value condition.
