[lttng-dev] [RELEASE] Userspace RCU 0.11.4, 0.12.3 and 0.13.1

[Mathieu Desnoyers]

Hi,

This is a release announcement for the currently maintained stable
branches of the Userspace RCU library. Please note that 0.11.4 is
the last release of the 0.11 stable branch, which is reaching end
of life. Users facing issues with the 0.11 stable branch are expected
to upgrade to 0.12.3 or 0.13.1.

The content of those bug fix releases is fairly straightforward,
and the change log small enough to be shown in this release
announcement (see below).

Feedback is as always welcome!

Thanks,

Mathieu
