et al. Can you say 'registry'? Drupal now maintains an internal registry of
all functions or classes in the system, allowing it to lazy-load code files as
needed (reducing the amount of code that must be parsed on each request). The
list of included files is cached per menu callback for subsequent loading by
the menu router. This way, a given page request will have all the code it needs
but little else, minimizing time spent parsing unneeded code.
* Removes the hard-coded 'book' type and perform all node actions
equally on any node type via hook_nodeapi.
* Achieves 100% integration with the menu system. Improves
performance of book rendering.
* All the algorithms have been changed to use the tree data structure
returned by the menu system.
* Added support for 'multiple books'.
* Some UI improvements.
This is a momumental patch that took 69 iterations. Although there is
room for improvement, this is a big step forward. Thanks for the
persistence, pwolanin.
