14 * Rename trace_mark() API to ust_marker(). Old macros kept for
15 slow deprecation.
16 * Tracepoint API is now private to UST.
17 * Introduction of the TRACEPOINT_EVENT API (work in progress).
18 Please use ust_marker() API while we complete TRACEPOINT_EVENT.
19 * Privatize many headers which should have always been internal
20 to UST. At the moment, only marker.h should be included by
21 applications. When the TRACEPOINT_EVENT API will be completed,
22 then other headers will be useful for the application
23 (tracepoint_event.h, tracepoint.h and, indirectly, probe.h).
24 * Markers: merge fixes from LTTng 0.249 into marker.[ch].
25 * Add ust/version.h header file, which exports the UST version
26 installed.
27 * Move to liburcu 0.6. Update dependencies.
