+## 0.1.0
+
+* Remove `Server.handleRequest()` and `Server.parseRequest()`. Instead, `new
+  Server()` takes a `Stream` and a `StreamSink` and uses those behind-the-scenes
+  for its communication.
+
+* Add `Server.listen()`, which causes the server to begin listening to the
+  underlying request stream.
+
+* Add `Server.close()`, which closes the underlying request stream and response
+  sink.
+
 ## 0.0.2+3
 
 * Widen the version constraint for `stack_trace`.
