Version 2 (2006-06-04): Complete rewrite After the insight that simple security is impossible, Prometheus was rewritten from scratch ontop of a much cleaner and simpler basis. The only User-visible difference is that the SLOTS->LIST message got replaced by IMMEDIATE-SLOT-LIST. This message returns a list of immediate slots in the receiving object. Each element has three elements: The name of the getter, the name of the setter (or #f), and the type, where the type is one of 'VALUE, 'METHOD or 'PARENT. Version 1 (2005-08-09): Initial release The initial release of the system to the public: Prometheus rising.
