nginx 0.7.14的改进如下

    *) Change: now the ssl_certificate and ssl_certificate_key directives 
       have not default values.

    *) Feature: the "listen" directive supports the "ssl" parameter.

    *) Feature: now nginx takes into account a time zone change while 
       reconfiguration on FreeBSD and Linux.

    *) Bugfix: the "listen" directive parameters such as "backlog", 
       "rcvbuf", etc. were not set, if a default server was not the first 
       one.

    *) Bugfix: if URI part captured by a "rewrite" directive was used as a 
       query string, then the query string was not escaped.

    *) Bugfix: configuration file validity test improvements.
