No need to test is_presence_visible in _start_polling_local because we know it will be by when it's called

That was a breaking db change. You need to recreate the databases. (In reality, it's enough to just run the im.sql through your db and change the schema version)

Added roomName, a directive to compute a room name based on its alias (not aliases for now) and its users displaynames or ids

Little bit more on syncing APIs, need to know more about responses before more work can be done on it.

Fairly simple move of the call status widget to the header bar (and therefore into the index page rather than the rooms page).

Have MemoryDataStore's get_rooms_for_user_where_membership_is() return room membership event objects, as per interface contract
