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.
