Release v4.66.0

Added

• Reducers in models with named event sources and streams can now be rendered with a from filter. The generated Chronicle reducer only sees events routed to that event source, or to that event source and stream, so unrouted events and events on other streams no longer change the read model. Plans for a module, feature or slice include the event source definitions a filter refers to. Reactions with a from filter are still refused with STAGE-ESM-035, and the Stage Host and specification runs still refuse reducers. (part of #297) (part of #207)
