+## 2.3.0 - 2021-10-11
+* The `spawn` method can now resolve with non-unit outputs. [#369]
+* Add experimental (semver-exempt) `io-uring` feature for enabling async file I/O on linux. [#374]

 ## 2.2.0 - 2021-03-29
 * **BREAKING** `ActixStream::{poll_read_ready, poll_write_ready}` methods now return
   `Ready` object in ok variant. [#293]
   * Breakage is acceptable since `ActixStream` was not intended to be public.
