Hi everyone,

Today marks the release of the third LTTng 2.12 - (Ta) Meilleure
release candidate.

The second release candidate was skipped as the configure script
was garbled by my release script. I unfortunately noticed this
after having pushed the tag... Mea culpa!

Have a look at the first release candidate's release notes for an
overview of the features introduced in LTTng 2.12.

https://github.com/lttng/lttng-tools/releases/tag/v2.12.0-rc1

This release is named after "Ta Meilleure", a Northeast IPA beer
brewed by Lagabière. Translating to "Your best one", this beer gives
out strong aromas of passion fruit, lemon, and peaches. Tastewise,
expect a lot of fruit, a creamy texture, and a smooth lingering hop
bitterness.

Of note, the tracker API was changed and the lttng-track(1) and
lttng-untrack(1) man pages were updated to clarify the usage of the
new uid/gid tracking feature.

We have also integrated a number of bug fixes which made their way to
the master branch as we continue to work on the LTTng 2.13 release.

Be safe!
