+2.0.0
+=====
+
+* Breaking change: use of `origin` as a parameter for `publish`, `subscribe` and `unsubscribe` has been moved to the chaining-function `target(origin)`
+* Added feature: events can be published with multiple arguments. If the last argument is a function, it is treated as a callback that subscribers can call.
+* Added feature: `include(popup)` adds popups to the listing of frames to be messaged.
+* Added feature: `window.opener` will now be included in framebus messaging, if available.
