API.txt: $Id$ This file contains a log of changes to the API. API Version 2.0 Remove the deprecated callback-based behavior of the 'defaults' property on plugin types; array addition is now the only option. If you need more complex logic, do it with the 'process' callback. Introduce a global plugin type registration hook and remove the per-plugin type magic callbacks. Versions prior to 2.0 have been removed from this document. See the D6 version for that information.
