Hi,

Here is a release announcement of last bugfix releases for the 2.6.x
series of lttng ust and lttng modules. With the release of 2.8.0 done
today, this marks the end of life of the 2.6.x series.

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.
