first of all the project graduated (apache incubator -> apache top-level-project).
multiple modules have been added:
existing modules have been improved (e.g. optional support for jsf 2.2 specific parts).
the documentation has been improved (but there is still room for further improvements).
almost all myfaces-codi features have been ported to deltaspike and most of them have been improved.
two versions have been released and the next one will follow soon.
