+- Updated to 1.21.4
+  * https://nginx.org/en/CHANGES
+  * Support for NPN instead of ALPN to establish HTTP/2
+    connections has been removed.
+  * Now nginx rejects SSL connections if ALPN is used by the
+    client, but no supported protocols can be negotiated.
+  * The default value of the "sendfile_max_chunk" directive was
+    changed to 2 megabytes.
+  * The "proxy_half_close" directive in the stream module.
+  * The "ssl_alpn" directive in the stream module.
+  * The $ssl_alpn_protocol variable.
+  * Support for SSL_sendfile() when using OpenSSL 3.0.
+  * The "mp4_start_key_frame" directive in the ngx_http_mp4_module.
+  * In the $content_length variable when using chunked transfer encoding.
+  * After receiving a response with incorrect length from a proxied
+    backend nginx might nevertheless cache the connection.
+  * Invalid headers from backends were logged at the "info" level
+    instead of "error"; the bug had appeared in 1.21.1.
+  * Requests might hang when using HTTP/2 and the "aio_write" directive.
