 * Add `System::attach_to_tokio` method. [#173]
 
 ### Changed
-
-* Remove `'static` lifetime requirement for `Runtime::block_on` and `SystemRunner::block_on`. 
+* Update `tokio` dependency to `1`
+* Rename `time` module `delay_for` to `sleep`, `delay_until` to `sleep_until`, `Delay` to `Sleep` to keep inline with tokio.
+* Remove `'static` lifetime requirement for `Runtime::block_on` and `SystemRunner::block_on`.
+  These methods would accept &Self when calling.
   Remove `'static` lifetime requirement for `System::run` and `Builder::run`.
   `Arbiter::spawn` would panic when `System` is not in scope. [#207]
