nginx 1.1.6
*) Change in internal API: now module context data are cleared while
internal redirect to named location.
Requested by Yichun Zhang.
*) Change: if a server in an upstream failed, only one request will be
sent to it after fail_timeout; the server will be considered alive if
it will successfully respond to the request.
*) Change: now the 0x7F-0x1F characters are escaped as \xXX in an
access_log.
*) Feature: "proxy/fastcgi/scgi/uwsgi_ignore_headers" directives support
the following additional values: X-Accel-Limit-Rate,
X-Accel-Buffering, X-Accel-Charset.
*) Feature: decrease of memory consumption if SSL is used.
*) Bugfix: some UTF-8 characters were processed incorrectly.
Thanks to Alexey Kuts.
*) Bugfix: the ngx_http_rewrite_module directives specified at "server"
level were executed twice if no matching locations were defined.
*) Bugfix: a socket leak might occurred if "aio sendfile" was used.
*) Bugfix: connections with fast clients might be closed after
send_timeout if file AIO was used.
*) Bugfix: in the ngx_http_autoindex_module.
*) Bugfix: the module ngx_http_mp4_module did not support seeking on
32-bit platforms.
