+Cubemap 1.3.1, 2016-07-23
+
+ * Support Metacube timestamp blocks. This allows Metacube producers
+ to add timestamps at arbitrary places between blocks, which,
+ provided that the system clocks on both sides are in sync, allows
+ Cubemap to produce a latency measure. If the latency is very high
+ (and/or keeps going up), you will know that the network has problems
+ keeping up with transporting the stream, even in the absence of
+ other error messages.
+
+ At the time of release, only Nageru adds timestamp blocks;
+ VLC does not.
