nginx 0.3.24 *) Workaround: for bug in FreeBSD kqueue. *) Bugfix: now a response generated by the "post_action" directive is not transferred to a client. *) Bugfix: the memory leaks were occurring if many log files were used. *) Bugfix: the first "proxy_redirect" directive was working inside one location. *) Bugfix: on 64-bit platforms segmentation fault may occurred on start if the many names were used in the "server_name" directives; bug appeared in 0.3.18.
