779 *) Authz: Move the 'Require' directive from the core module as well as
780 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
781 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
782 logic into the authorization processing. [Brad Nicholes]
784 *) Authz: Add the new module mod_authz_core which acts as the
785 authorization provider vector and contains common authz
786 directives. [Brad Nicholes]
788 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
789 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
791 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle

807 *) Asynchronous write completion for the Event MPM. [Brian Pane]
809 *) Added an End-Of-Request bucket type. The logging of a request and
810 the freeing of its pool are now done when the EOR bucket is destroyed.
811 This has the effect of delaying the logging until right after the last
812 of the response is sent; ap_core_output_filter() calls the access logger
813 indirectly when it destroys the EOR bucket. [Brian Pane]

816 and the format of statistical output has changed. [Colm MacCarthaigh]
