+Version 2.9.5.7 – Development Version
+----
+Version 2.9.5.7 contains general bug fixes and enhancements for some special situations.
+**Bug Fixes**
+* Getting delay and latency information from the `alsa` subsystem has been improved -- bugs fixed, error codes handled better, arithmetic handling (hopefully) better. 
+* If latency information is temporarily unavailable from the `alsa` subsystem, skip trying to synchronise until the next time.
+* Some condition variables and a mutex were uninitialised, yikes! Fixed.
+* A bug that set the output volume to maximum at the same time as muting the output has been fixed. AFAIK, this was inaudible, but it was scary looking.
+* Recover from name collisions in Avahi.
+* Detect and handle empty buffers better.
+**Enhancements**
+* Turn off synchronisation. This is an advanced feature and generally leads to buffer underrun or overrun.
+* Set `alsa` buffer size and `alsa` period size. There are advanced features, mainly for debugging. They may be removed.
+* Change the Zeroconf/Bonjour `regtype` to enable Shairport Sync to continue to run but to be invisible to AirPlay clients. Special purpose usage only.
+* Output total number of packets and the play time of a session when statistics are enabled.
