2 | * Add backward compability for tracepoint API (still planned for | |
3 | deprecation, but should make the transition smoother). | |

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. | |
