Release Notes: This release fixes two EventMachine bugs.
Release Notes: This release adds a bugfix to allow stream(:keep_open) in Sinatra (and possibly other async.callback users) to work properly with EventMachine. There are no changes for non-EventMachine users.

Release Notes: For epoll/Cool.io-based concurrency models, shutdown() is now used to timeout keepalive clients to avoid race conditions. Minor documentation improvements were made.
