- App events, can be polled by apps using the HTTP API
- Node events, can be processed by a node implementation by registering a callback in the `Ubisync` object
- Some further additions, like adding pot members etc. to test these new event functions
- State changes can now be handled differently, depending on whether they were caused locallly (API) or by a remote peer (Comm)
- State functions have more readable names (`write...` and `update...` have similar meanings, but using different names helps readability in the respective (API/Comm) context)
