After #1827414: Move default tracking code to it's own module we need to implement a hook_update_N to prevent breaking sites when they update to the latest version.
Attached is a mixpanel.install file which does this (remove the .txt, of course! d.o won't let me upload a .install file).
Please let me know what you think!
Sorry I missed that file in the last patch.
