+Version 3.1d6
+====
+**New Feature**
+An extensively enhanced and updated backend for SNDIO thanks to the work of [t6](https://github.com/t6).
+
+SNDIO is *"the software layer of the OpenBSD operating system that manages the use of sound cards and MIDI ports."* Additionally, SNDIO *"... pays special attention to synchronization mechanisms and reliability required by music applications"*, hopefully opening up the possibility of synchronisation native to \*BSD.

Version 3.1s5
====
Generally, more extensive changes have been to make all relevant operations reentrant.
