Changes with nginx 1.19.1                                        07 Jul 2020

    *) Change: the "lingering_close", "lingering_time", and
       "lingering_timeout" directives now work when using HTTP/2.

    *) Change: now extra data sent by a backend are always discarded.

    *) Change: now after receiving a too short response from a FastCGI
       server nginx tries to send the available part of the response to the
       client, and then closes the client connection.

    *) Change: now after receiving a response with incorrect length from a
       gRPC backend nginx stops response processing with an error.

    *) Feature: the "min_free" parameter of the "proxy_cache_path",
       "fastcgi_cache_path", "scgi_cache_path", and "uwsgi_cache_path"
       Thanks to Adam Bambuch.

    *) Bugfix: nginx did not delete unix domain listen sockets during
       graceful shutdown on the SIGQUIT signal.

    *) Bugfix: zero length UDP datagrams were not proxied.

    *) Bugfix: proxying to uwsgi backends using SSL might not work.
       Thanks to Guanzhong Chen.

    *) Bugfix: in error handling when using the "ssl_ocsp" directive.

    *) Bugfix: on XFS and NFS file systems disk cache size might be
       calculated incorrectly.

    *) Bugfix: "negative size buf in writer" alerts might appear in logs if
       a memcached server returned a malformed response.
