Hi there,

I’m a bit confused about the version of infinispan I should use running keycloak 11.0.0

I’m running an inifispan 9.4 cluster apart from keycloak at the moment.

Which version of infinispan should I use, I found mention of infinispan 10.1.8 but in keycloak domain mode documentation it’s still the 9.4 that is used.

And it seems there is a huge difference between infinispan 9x and 10 …
