ChangeLog

   1 2011-07-15 ust 0.15
   2         * Add backward compability for tracepoint API (still planned for
   3           deprecation, but should make the transition smoother).
   4
   5 2011-06-12 ust 0.14
   6         * Rename trace_mark() API to ust_marker(). Old macros kept for
   7           slow deprecation.
   8         * Tracepoint API is now private to UST.
   9         * Introduction of the TRACEPOINT_EVENT API (work in progress).
  10           Please use ust_marker() API while we complete TRACEPOINT_EVENT.
  11         * Privatize many headers which should have always been internal
  12           to UST. At the moment, only marker.h should be included by
  13           applications. When the TRACEPOINT_EVENT API will be completed,
  14           then other headers will be useful for the application
  15           (tracepoint_event.h, tracepoint.h and, indirectly, probe.h).
  16         * Markers: merge fixes from LTTng 0.249 into marker.[ch].
  17         * Add ust/version.h header file, which exports the UST version
  18           installed.
  19         * Move to liburcu 0.6. Update dependencies.
