+* Upgrading to thrift 0.14.0
+
+1.22.4
+
+* Updates which result in a no-op now return a response value so that the caller may analyze it to determine what happened
+
+1.22.3
+
+* Contains a monitor timeout fix. Previously an error was being left unchecked which made a specific monitor timining out not be handled properly.
+
+1.22.2

 * CreateService and StartJobUpdate do not continue retrying if a timeout has been encountered
 by the HTTP client. Instead they now return an error that conforms to the Timedout interface.
