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.
I'll tag 5.0.0 final in a week or so if all goes well

* [PATCH 0/4] a few more minor cleanups pushed out

Not much going on other than killing old stuff and minor cleanups.
I'll probably give systemd a try soon and see if the
"unicorn_forever" script makes sense to bundle:
http://bogomips.org/unicorn-public/m/20130724031151.GA14534@dcvr.yhbt.net.txt
Since CoW-friendliness is important to unicorn users, I think we'll
always have to manage our own process forking.
For now, I think using the UNICORN_FD environment variable
(comma-delimited list of integer file descriptors) and matching "listen"
directives is enough to get started. Perhaps supporting something like:
listen :inherit
...can help DRY-up configurations so users won't have to specify
redundant listen directives. Ruby startup times are still horrific; so
I don't think anybody wants to use socket activation with on-demand
fork+exec of unicorn processes.
The following changes since commit f203eaae7ea84de9e974ea5dac2df97d664d8e61:

Whatever compatibility reasons which existed in 2009 likely do not exist
now. Other servers (e.g. thin, puma) seem to work alright without it,
so there's no reason to waste precious bytes.

The only user-visible change would be the removal of the Status:
header from the HTTP response, but I doubt anybody would even
notice.
