Subject: Changes with nginx 0.6.23                                        27
 Dec 2007

    *) Change: the "off" parameter in the "ssl_session_cache" directive;
       now this is default parameter.

    *) Change: the "open_file_cache_retest" directive was renamed to the
       "open_file_cache_valid".

    *) Feature: the "open_file_cache_min_uses" directive.

    *) Feature: the ngx_http_gzip_static_module.

    *) Feature: the "gzip_disable" directive.

    *) Feature: the "memcached_pass" directive may be used inside the "if"
       block.

    *) Bugfix: a segmentation fault occurred in worker process, if the
       "memcached_pass" and "if" directives were used in the same location.

    *) Bugfix: if a "satisfy_any on" directive was used and not all access
       and auth modules directives were set, then other given access and
       auth directives were not tested;

    *) Bugfix: regex parameters in a "valid_referers" directive were not
       inherited from previous level.

    *) Bugfix: a "post_action" directive did run if a request was completed
       with 499 status code.

    *) Bugfix: optimization of 16K buffer usage in a SSL connection.
       Thanks to Ben Maurer.

    *) Bugfix: the STARTTLS in SMTP mode did not work.
       Thanks to Oleg Motienko.

    *) Bugfix: in HTTPS mode requests might fail with the "bad write retry"
       error; bug appeared in 0.5.13.
