Keycloak 15 Infinispan version

I am trying to upgrade from Keycloak 12 to 15. I have noticed that the version for local Infinispan in pom.xml is <infinispan.version>11.0.9.Final</infinispan.version> , as for remote it is set to <subsystem xmlns="urn:jboss:domain:infinispan:12.0"> in keycloak-infinispan.xml. Does anyone know why is there a mismatch in versions for local and remote Infinispan?
