Hi Jonathan, Thanks for putting this RC together. You stated that there are improvements related to rolling upgrades from 2.x to 3.x and I know I have seen multiple JIRAs getting committed to that effect. Could you describe any tests that you have done to verify rolling upgrade compatibility for 3.x servers talking to 2.x clients and vice versa?
