+2011-12-15 ust 0.16
+ * Use caa_unlikely, depend on liburcu >= 0.6.6
+ * usttrace: allow spaces in command-line arguments
+ * Fix tracepoint test with deprecated API
+ * Add powerpc64 host_cpu to configure.ac
+ * Mark __tp_cb_data as possibly unused for backward compat API
+ * Fix git URL
+
+2011-07-15 ust 0.15
+ * Add backward compability for tracepoint API (still planned for
+ deprecation, but should make the transition smoother).
+
+2011-06-12 ust 0.14
+ * Rename trace_mark() API to ust_marker(). Old macros kept for
+ slow deprecation.
+ * Tracepoint API is now private to UST.
+ * Introduction of the TRACEPOINT_EVENT API (work in progress).
+ Please use ust_marker() API while we complete TRACEPOINT_EVENT.
+ * Privatize many headers which should have always been internal
+ to UST. At the moment, only marker.h should be included by
+ applications. When the TRACEPOINT_EVENT API will be completed,
+ then other headers will be useful for the application
+ (tracepoint_event.h, tracepoint.h and, indirectly, probe.h).
+ * Markers: merge fixes from LTTng 0.249 into marker.[ch].
+ * Add ust/version.h header file, which exports the UST version
+ installed.
+ * Move to liburcu 0.6. Update dependencies.
+
