Changes with Apache 2.3.0
[ When backported to 2.2.x, remove entry from this file ]
*) mod_proxy_http: Do not forward requests with 'Expect: 100-continue' to
known HTTP/1.0 servers. Return 'Expectation failed' (417) instead.
[Ruediger Pluem]
*) core, authn/z: Determine registered authn/z providers directly in
ap_setup_auth_internal(), which allows optional functions that just
wrapped ap_list_provider_names() to be removed from authn/z modules.
