Nginx 1.11 がリリースされました

変更点はこちら。

*) Feature: the "transparent" parameter of the "proxy_bind",
   "fastcgi_bind", "memcached_bind", "scgi_bind", and "uwsgi_bind"
   directives.

*) Feature: the $request_id variable.

*) Feature: the "map" directive supports combinations of multiple
   variables as resulting values.

*) Feature: now nginx checks if EPOLLRDHUP events are supported by
   kernel, and optimizes connection handling accordingly if the "epoll"
   method is used.

*) Feature: the "ssl_certificate" and "ssl_certificate_key" directives
   can be specified multiple times to load certificates of different
   types (for example, RSA and ECDSA).

*) Feature: the "ssl_ecdh_curve" directive now allows specifying a list
   of curves when using OpenSSL 1.0.2 or newer; by default a list built
   into OpenSSL is used.

*) Change: to use DHE ciphers it is now required to specify parameters
   using the "ssl_dhparam" directive.

*) Feature: the $proxy_protocol_port variable.

*) Feature: the $realip_remote_port variable in the
   ngx_http_realip_module.

*) Feature: the ngx_http_realip_module is now able to set the client
   port in addition to the address.

*) Change: the "421 Misdirected Request" response now used when
   rejecting requests to a virtual server different from one negotiated
   during an SSL handshake; this improves interoperability with some
   HTTP/2 clients when using client certificates.

*) Change: HTTP/2 clients can now start sending request body
   immediately; the "http2_body_preread_size" directive controls size of
   the buffer used before nginx will start reading client request body.

*) Bugfix: cached error responses were not updated when using the
   "proxy_cache_bypass" directive.

個人的に気になったのは

$request_id 導入
- リクエストIDをヘッダーに付与することができると何かと便利に使えそう
ssl_certificate / ssl_certificate_key を複数回指定できる
- RSA と ECDSA の証明書をデュアルで指定できたりする
HTTP/2 でも proxy_request_buffering off のような挙動にできるようになった(と理解した)
- 以前記事にしたようなことが HTTP/2 でも回避できるんじゃないかと期待 racchai.hatenablog.com
