RabbitMQ Cluster Operator compatibility

[goniko]

Hi

I'm wondering if someone can point me to information about the compatibility between different Operator and Cluster versions. Backwards compatibility is well documented. So for instance, Operator v2.0 states the minimum Cluster version of 3.9.9. Is the previous major version of the operator (e.g. v1.14) compatible with later Cluster versions (e.g. 3.10, 3.11), or is there a maximum tested version, so that there is effectively only a small overlap in what Operator 1 and 2 are both compatible with?
I am trying to decide whether upgrading through to the latest RabbitMQ requires me to first upgrade the operator while at 3.9, before proceeding 3.10, 3.11...etc, or whether I can upgrade all the way and then change the operator.
