nginx 0.8.34 *) Bugfix: nginx did not support all ciphers and digests used in client certificates.

Thanks to Maxim Dounin. *) Bugfix: if ssl_session_cache was not set or was set to "none", then during client certificate verify the error "session id context uninitialized" might occur; the bug had appeared in 0.7.1. *) Bugfix: a geo range returned default value if the range included two or more /16 networks and did not begin at /16 network boundary. *) Bugfix: a block used in a "stub" parameter of an "include" SSI directive was output with "text/plain" MIME type. *) Bugfix: $r->sleep() did not work; the bug had appeared in 0.8.11.
