2.4.1.6 release notes

2.4.1.6 - Hotfix for 2.4.1.5

• Issue 3001 - For some reason the compiler marked the catch block for UnexpectedErrorFault as invalid in IC's expired/invalid session handling logic, so I removed it. Sure enough, though, that exception still occurs, and now IC wasn't handling and recovering from it properly any longer. This is a targeted hotfix to restore that handling, albeit in a manner that the compiler no longer flags.
