I am happy that i am part of the Sametime Next beta community, so that i could test (since july 2013) the new version.
The first thing i am realy happy is that IBM updates with Sametime Next their Websphere Version to 8.5.x (beta release) and therefore you could use JVM with 64bit. I think this makes the product more scalable.
Also there will be a change in the Sametime product offering (communicate+conference = complete) – i am not quite sure if this is additional (entry, standard or advance license) or a replacement.
But prepare Your enviroment for more machines 🙂 a/v will use it ….
More (in detail) information will be posted when Sametime Next will be officially released.
