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.

In this release, we drop the lttng-ust-java java tracing library, since
the API was not deemed ready for use at this stage (no API exposed in
2.0, anyway, this was simply a library). We will work on it for 2.1.

Also noteworthy in this release, signals are now blocked in listener
UST threads, and /dev/shm filesystem full conditions are now handled so
it never triggers an SIGBUS in a traced application. 2.0.x users are
encouraged to upgrade.
