Hi,Wednesday at Google IO, Google did announce the availability of Firebase Cloud Messaging (FCM), which deprecates Google Cloud Messaging (GCM).Here is a quite from the GCM documentation website:>>Firebase Cloud Messaging (FCM) is the new version of GCM. It inherits the reliable and scalable GCM infrastructure, plus new features! See the FAQ to learn more. If you are integrating messaging in a new app, start with FCM. GCM users are strongly recommended to upgrade to FCM, in order to benefit from new FCM features today and in the future.<<At the core FCM is basically the same as GCM-3 (e.g. topic support), but there are some changes especially in the client SDKs. I've created a few JIRAs to scope the body of work, needed to deliver FCM support on our SDKs, as well keeping our server and documentation in sync with the latest offering: https://issues.jboss.org/issues/?filter=12327296Greetings,Matthias--Matthias Wessendorf
