       "variables_hash_bucket_size" directives.

       "log_format" directive.

    *) Feature: the $ssl_protocol and $ssl_cipher variables.

    *) Feature: the cache line size detection for widespread CPUs at start
       time.

    *) Feature: now the "accept_mutex" directive is supported using
       fcntl(2) on platforms different from i386, amd64, sparc64, and ppc.

       then the requests with the body was not transferred.
