Hi team, here is an epic to support GCM3 for 1.2.0: https://issues.jboss.org/browse/AGPUSH-1453 Especially the "topic messaging" sub-task is kick ass! This means we need to map our categories to GCM topics, and that allows us to ping all devices, with a single request, to GCM. That is an extremely awesome boost! The epic contains a 35 min. video of the new GCM 3.0 changes. Very cool, it also takes about the iOS/GCM mapping (at least worth to explore / evaluate) -Matthias -- Matthias Wessendorf blog: http://matthiaswessendorf.wordpress.com/ sessions: http://www.slideshare.net/mwessendorf twitter: http://twitter.com/mwessendorf
