I have a customer who found an issue when someone try to connect with their Studio 10.6 install to their development OO v10.8 server. It wouldn't connect, and then people with the v.10.8 install were unable to use Studio with the dev server.
Issue was fix performing the following steps:
truncate table OO_RUNNING_EXECUTION_PLANS;
truncate table OO_CACHED_EXECUTION_PLANS;
However, they are concerned that an older version of OO Studio could break Their OO 10.8 install via db corruption.
With that scenario in mind, it will be beneful if the remote debugger checks that Studio and Central versions match in order to allow the connection and in that way avoid this kind of issues.
