[Mathieu Desnoyers]

Hi,

Here is a release announcement of bugfix releases for lttng ust and
lttng modules.

LTTng-UST, the Linux Trace Toolkit Next Generation Userspace Tracer,
is a low-overhead application tracer. The library "liblttng-ust" enables
tracing of applications and libraries.

The LTTng modules provide Linux kernel tracing capability to the LTTng
2.x tracer toolset.
