=== unicorn 4.5.0 - check_client_connection option / 2012-12-07 22:59 UTC
The new check_client_connection option allows unicorn to detect
most disconnected local clients before potentially expensive
application processing begins.
This feature is useful for applications experiencing spikes of
traffic leading to undesirable queue times, as clients will
disconnect (and perhaps even retry, compounding the problem)
before unicorn can even start processing the request.
To enable this feature, add the following line to a unicorn
config file:
check_client_connection true
This feature only works when nginx (or any other HTTP/1.0+
client) is on the same machine as unicorn.
A huge thanks to Tom Burns for implementing and testing this
change in production with real traffic (including mitigating
an unexpected DoS attack).

=== unicorn 4.4.0 - minor updates / 2012-10-11 09:11 UTC
Non-regular files are no longer reopened on SIGUSR1. This
allows users to specify FIFOs as log destinations.
TCP_NOPUSH/TCP_CORK is no longer set/unset by default. Use
:tcp_nopush explicitly with the "listen" directive if you wish
to enable TCP_NOPUSH/TCP_CORK.
Listen sockets are now bound _after_ loading the application for
preload_app(true) users. This prevents load balancers from
sending traffic to an application server while the application
is still loading.
There are also minor test suite cleanups.
