The lttng-tools project provides a session daemon (lttng-sessiond) that acts as
a tracing registry, the "lttng" command line for tracing control, the
liblttngctl library also for tracing control and the liblttng-consumer library
to create your own LTTng 2.0 consumer.

The *major* feature of this release is the user-space tracing support for
lttng-ust 2.0. Also notice the dependency for user-space RCU >= 0.6.7.
