we have just successfully voted new releases of 6 different
subprojects, and I'd like to launch soon 4 more releases so that,
when successful, all subprojects  will have a stable release we
can reference from C3 parent POM : this would allow, in the
medium run, to discuss whether to make some C3 milestone releases,
as already outlined in some past mail thread.
Now my question is: do you think that we should publicly announce
such subprojects releases? I would say "no", at least not
individually, since the functionality of some of them is not so easy
Maybe a single announcement for all subprojects - only at the end of
this release process - could be better.
