Changes with nginx 1.15.2:
*) 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.

Changes with nginx 1.15.1:
*) Feature: the "random" directive inside the "upstream" block.
*) Feature: improved performance when using the "hash" and \ 
"ip_hash"
   directives with the "zone" directive.
*) Feature: the "reuseport" parameter of the "listen" \ 
directive now uses
   SO_REUSEPORT_LB on FreeBSD 12.
*) Bugfix: HTTP/2 server push did not work if SSL was terminated by a
   proxy server in front of nginx.
*) Bugfix: the "tcp_nopush" directive was always used on backend
   connections.
*) Bugfix: sending a disk-buffered request body to a gRPC backend might
   fail.
