Interim gLite release process • EGEE project finished on April 2010 • EMI project started on May 2010 • Until EMI (and EGI) are able to take care of the releases there is a transition period where: • WLCG is the driving force behind the gLite releases until EMI takes over • We will try to keep LCG and EMI related work as much aligned as possible • How long ? • The first EMI release is scheduled for March-April 2011 Middleware Update - M.
