+====
+**Pesky Changes**
+* The underlying timing system has been moved from 64-bit fixed-point time representation (a là NTP) to a 64-bit unsigned nanoseconds representation. This should make precisely no difference to the functionality of Shairport Sync but the transition might behabve inadeventely introduced bugs. Problem reports gratefully received.
