ChangeLog

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