[Mathieu Desnoyers]

LTTng-UST, the Linux Trace Toolkit Next Generation Userspace Tracer, is
port of the low-overhead tracing capabilities of the LTTng kernel tracer
to user-space. The library "liblttng-ust" enables tracing of
applications and libraries.

This announces bugfix releases across the three stable branches:
stable-2.5 (near EOL), stable-2.6, and stable-2.7 (in release candidate
stage).
