[infinispan-dev] public API/what should be preserve between minor releases?

[Tomas Sykora]

Hi guys,

is this topic related?
https://community.jboss.org/wiki/RollingUpgradesInInfinispan

I'd assume that *whole* cluster will be upgraded to some higher version. Running cluster with different versions seems risky to me too. This ^^ process should be smooth but I don't know how about changes in API.

I'm very interested in this topic - that's the reason why I jumped in to your discussion.
Thank you!

Thats the plan for our own software. Customer can update the nodes one 
by one, of course only for patch releases.
I'd expect (or at least hope) that this will be also possible with 
infinispan in case of critical bug was fixed or smth.
