+LTTng-tools supports both the [LTTng Linux Kernel tracer](https://lttng.org)
+and [LTTng user space tracer](https://lttng.org) released as part of the same
+**minor** release series. While some releases do not change the tracer ABIs and

+Note that applications instrumented with older versions of the LTTng UST project
+do not have to be rebuilt or modified to work with the latest LTTng-tools.
+For more information on versioning, please refer to the
