When we update the Test module, developers need to re-enable Test on their existing applications that they've enabled for the service. This is mentioned in the release notes, but it would be nice if the Update dialog (attached) for the Test Module also mentioned this and linked to the relevant documentation (http://docs.appcelerator.com/platform/latest/#!/guide/Re-enabling_Test_After_Service_Upgrade).
Here is some copy we could append to the current text:
You must re-enable Test on any Titanium applications that you had previously Test-enabled. See Re-enabling Test After Service Upgrade for details.
