*) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
*) Fix typo in ProxyStatus syntax error message.
[Christophe Jaillet <christophe.jaillet wanadoo.fr>]
*) Asynchronous write completion for the Event MPM. [Brian Pane]
*) Added an End-Of-Request bucket type. The logging of a request and
the freeing of its pool are now done when the EOR bucket is destroyed.
This has the effect of delaying the logging until right after the last
of the response is sent; ap_core_output_filter() calls the access logger
indirectly when it destroys the EOR bucket. [Brian Pane]
*) Rewrite of logresolve support utility: IPv6 addresses are now supported
and the format of statistical output has changed. [Colm MacCarthaigh]
*) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
*) Added new connection states for handler and write completion
[Brian Pane]
*) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
[Justin Erenkrantz]
*) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
allowing string-valued client certificate attributes to be used for
access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
