The Kepler Simultaneour Release wiki
refers the simultaneousrelease flag in metadata, but at
the current moment there is no "Kepler" value for this
flag. Also the list of participating projects (http://www.eclipse.org/projects/releases/releases.php?release=kepler)
shows data from Juno.
Please announce here the metadata
properties that should be configured in order to join the
Kepler release once these properties will be available in
metadata configuration. It will be better to configure
these properties together with Kepler scheduling. Previous
times I had to check these properties multiple times to
find the moment when they can be configured and once
forgot to recheck and failed M4 due date because of this.
