 Changes with Apache 2.5.1
 
+  *) event: Add support for non blocking behaviour in the
+     CONN_STATE_READ_REQUEST_LINE phase, in addition to the existing
+     CONN_STATE_WRITE_COMPLETION phase. Add AP_MPM_CAN_AGAIN and AGAIN to
+     signal to the MPM that non blocking behaviour is requested. Update
+     mod_ssl to perform non blocking TLS handshakes. [Graham Leggett]
+
   *) http: Enforce that fully qualified uri-paths not to be forward-proxied
      have an http(s) scheme, and that the ones to be forward proxied have a
      hostname, per HTTP specifications.  [Ruediger Pluem, Yann Ylavic]

+     Previously the correct event was polled for, but the response to the poll
+     would call write instead of read, and read instead of write. PR 55952
