In the past, there have been several cases where updates were made to
the Mercury core of Xenomai that required changes in existing
applications. Possibly this depended on how exactly you link to it and
which startup options you give, but anyway this is a situation where
being able to select a non-latest xenomai version can be useful, at
least in a transition phase.
