<li>Initial timeplan available 2-4 weeks before the planned branchpoint (rc1)
on the mesa-announce@ mailing list.

+candidates. Additional ones may be needed in order to resolve blocking

The final release from the 12.0 series Mesa 12.0.5 will be out around the same
time (or shortly after) 13.0.1 is out.
+<br>
+This also involves that, as a final release may be delayed due to the
+need of additional candidates to solve some blocking regression(s),
+the release manager might have to update
+the <a href="release-calendar.html" target="_parent">calendar</a> with
+additional bug fix releases of the current stable branch.
