[Maxim Dounin]

Changes with nginx 1.19.3                                        29 Sep 2020

    *) Feature: the ngx_stream_set_module.

    *) Feature: the "proxy_cookie_flags" directive.

    *) Feature: the "userid_flags" directive.

    *) Bugfix: the "stale-if-error" cache control extension was erroneously
       applied if backend returned a response with status code 500, 502,
       503, 504, 403, 404, or 429.

    *) Bugfix: "[crit] cache file ... has too long header" messages might
       appear in logs if caching was used and the backend returned responses
       with the "Vary" header line.

    *) Workaround: "[crit] SSL_write() failed" messages might appear in logs
       when using OpenSSL 1.1.1.

    *) Bugfix: "SSL_shutdown() failed (SSL: ... bad write retry)" messages
       might appear in logs; the bug had appeared in 1.19.2.

    *) Bugfix: a segmentation fault might occur in a worker process when
       using HTTP/2 if errors with code 400 were redirected to a proxied
       location using the "error_page" directive.

    *) Bugfix: socket leak when using HTTP/2 and subrequests in the njs
       module.
