    *) Change: the "lingering_close", "lingering_time", and

    *) 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"
       directives.
       Thanks to Adam Bambuch.
