nginx 1.1.9 *) Change: now double quotes are encoded in an "echo" SSI-command output. Thanks to Zaur Abasmirzoev. *) Feature: the "valid" parameter of the "resolver" directive. By default TTL returned by a DNS server is used. Thanks to Kirill A. Korinskiy. *) Bugfix: nginx might hang after a worker process abnormal termination. *) Bugfix: a segmentation fault might occur in a worker process if SNI was used; the bug had appeared in 1.1.2. *) Bugfix: in the "keepalive_disable" directive; the bug had appeared in 1.1.8. Thanks to Alexander Usov. *) Bugfix: SIGWINCH signal did not work after first binary upgrade; the bug had appeared in 1.1.1. *) Bugfix: backend responses with length not matching "Content-Length" header line are no longer cached. *) Bugfix: in the "scgi_param" directive, if complex parameters were used. *) Bugfix: in the "epoll" event method. Thanks to Yichun Zhang. *) Bugfix: in the ngx_http_flv_module. Thanks to Piotr Sikora. *) Bugfix: in the ngx_http_mp4_module. *) Bugfix: IPv6 addresses are now handled properly in a request line and in a "Host" request header line. *) Bugfix: "add_header" and "expires" directives did not work if a request was proxied and response status code was 206. *) Bugfix: nginx could not be built on FreeBSD 10. *) Bugfix: nginx could not be built on AIX.

 * FreeBSD does not test /etc/localtime change, however, we can workaround it

 * Linux does not test /etc/localtime change in localtime(),
 * but may stat("/etc/localtime") several times in every strftime(),
 * therefore we use it to update timezone.
 *
 * Solaris does not test /etc/TIMEZONE change too and no workaround available.
