+Version 3.1.d22
+====
+**Bug Fix**
+* When playing to a non-synchromnised backend, such as the stdout or pipe backends, Shirport Sync introduces a long delay. This is an attempt to fix that problem. The silent lead-in time should now be roughlt equal to the latency set betwby the client -- usually two seconds. 
+
+**Enhancement**
+* Some parameters in the new PulseAudio back end are now settable -- the Application Name, the buffer length and a delay offset. More details later.
