+Version 3.1.d24
+====
+**Enhancements**
+* The `audio_backend_buffer_desired_length_in_seconds` and `audio_backend_latency_offset_in_seconds` settings have been moved from individual backend stanzas to the `general` stanza. They are now available for all backends.
+* A new general setting, for advanced use only, called `audio_backend_silent_lead_in_time` had been introduced to set the length of the silent lead-in time from 0.050 seconds up to approximately the latency.
+* It is now possible to read `stdout` from the on-start command to choose ALSA output device. This is a highly specialised facility (i.e. a kind of hack) and will hopefully be replaced by a more general solution. Thanks to [Cody Cutrer](https://github.com/ccutrer) for it.
+**Bug Fixes**
+* Fixed a typo in shairport.c, thanks to [Troy Liu](https://github.com/troyliu0105).

 Thanks to [Paul Guyot](https://github.com/pguyot) for this work.
