"uwsgi_bind" directives.
*) Feature: improved CPU cache line size detection.
Thanks to Debayan Ghosh.

process with PID different from 1 after its parent process has
finished.

with bodies.
*) Bugfix: in the "proxy_limit_rate" directive when used with the
"keepalive" directive.

"proxy_buffering off" if the client connection used SSL.
