We try to notify this list when API changes are made in Drupal 7, so contrib and custom developers have a chance to fix their code before they have the pain of figuring out why it's broken.

The entity_invoke() function has been removed (issue). All calls to entity_invoke('whatever') must be replaced by the equivalent module_invoke('entity_whatever', ...). If your module uses entity_invoke, take a look at the simple patch in http://drupal.org/node/834924 to see the fix required.

Thanks,
-Randy
