 ## `Session` is now clonable and can be closed easily
 
-`Session` implements `Clone` now, so there is no more need to wrap it into an `Arc<Session>`, and `Session::into_arc` has been deprecated. All the session methods, except `Session::close`, works like before, so only the session type will would to be changed.

+As a side effect, `Subscriber` and `Queryable` no longer have a generic lifetime parameter. `Publisher` also looses one of its lifetime parameters, to keep only the one of its key expression.
 
 The session is now closed automatically when the last `Session` instance is dropped, **even if publishers/subscribers/etc. are still alive**. Session can also be manually closed using `Session::close`, which now takes an immutable reference, so it can be called anytime, even if publishers/subscribers/etc. are still alive.
