• storing a Runtime instance in a thread-local (#2011).
• miscellaneous documentation fixes.
• rt: fix Waker::will_wake to return true when tasks match (#2045).
• test-util: time::advance runs pending tasks before changing the time (#2059).

Added

• net::lookup_host maps a T: ToSocketAddrs to a stream of SocketAddrs (#1870).
• process::Child fields are made public to match std (#2014).
• impl Stream for sync::broadcast::Receiver (#2012).
• sync::RwLock provides an asynchonous read-write lock (#1699).
• runtime::Handle::current returns the handle for the current runtime (#2040).
• StreamExt::filter filters stream values according to a predicate (#2001).
• StreamExt::filter_map simultaneously filter and map stream values (#2001).
• StreamExt::try_next convenience for streams of Result<T, E> (#2005).
• StreamExt::take limits a stream to a specified number of values (#2025).

• StreamExt::all tests if every element of the stream matches a predicate (#2035).
• StreamExt::any tests if any element of the stream matches a predicate (#2034).
