unicorn 5.0.0.pre1 - incompatible changes!
This release finally drops Ruby 1.8 support and requires Ruby 1.9.3
or later.  The horrible "Status:" header in our HTTP response is
finally gone, saving at least 16 precious bytes in every single HTTP
response.

Under Ruby 2.1 and later, the monotonic clock is used for timeout
handling for better accuracy.

Several experimental, unused and undocumented features are removed.

There's also tiny, minor performance and memory improvements from
dropping 1.8 compatibility, but probably nothing noticeable on a
typical real-life (bloated) app.

The biggest performance improvement we made was to our website by
switching to olddoc.  Depending on connection speed, latency, and
renderer performance, it typically loads two to four times faster.

Finally, for the billionth time: unicorn must never be exposed
to slow clients, as it will never ever use new-fangled things
like non-blocking socket I/O, threads, epoll or kqueue.  unicorn
must be used with a fully-buffering reverse proxy such as nginx
for slow clients.
