#Smithereen update. (there aren't many of these lately as I'm also working on the Mastodon Android app)
- Added a "collection query" endpoint to actors. This allows asking an actor "do you have this object in your collection?". Simple form-data post request, up to 100 object ids at a time.
- Add{Person} and Add{Group} make use of this. If the other party confirms that this actor is, in fact, a friend/member, that relationship gets stored in the DB right away.
