+* Tweak: When a field has moved outside of a group, disallow deleting that group until the Pod has been saved to prevent those fields being removed/orphaned. #6940 #6937 (@zrothauser, @sc0ttkclark)
+* Tweak: When registering code-based fields, if you have a relationship field that you are supplying the `'data'` option for, you can now pass in a callable function (not a string or array due to back-compat) to return the options only when the data is needed instead of every page load. (@sc0ttkclark)
