Nginx
  • Feature: the $ssl_preread_protocol variable in the ngx_stream_ssl_preread_module.
  • Feature: now when using the “reset_timedout_connection” directive nginx will reset connections being closed with the 444 code.
  • Change: a logging level of the “http request”, “https proxy request”,”unsupported protocol”, and “version too low” SSL errors has been lowered from “crit” to “info”.
  • Bugfix: DNS requests were not resent if initial sending of a request failed.
  • Bugfix: the “reuseport” parameter of the “listen” directive was ignored if the number of worker processes was specified after the “listen” directive.
  • Bugfix: when using OpenSSL 1.1.0 or newer it was not possible to switch off “ssl_prefer_server_ciphers” in a virtual server if it was switched on in the default server.
  • Bugfix: SSL session reuse with upstream servers did not work with the TLS 1.3 protocol.
