Rainbows! is an HTTP server for sleepy Rack applications.
While it will be maintained as long as anybody uses it,
use of Rainbows! for new projects is not recommended,
try other servers instead:

Rainbows! 5.0.0 - maintained as long as anybody uses it!
This release syncs with unicorn 5 and drops some old compatibility
cruft from old releases. Performance should be roughly unchanged
for Ruby 2.2 users while older Rubies (1.9.3 - 2.1) will see
minor, probably unnoticeable performance regressions.
Compatibility:
* The horrible, proprietary (:P) "Status:" response header is
finally gone, saving at least 16 precious bytes in every HTTP
response. This should make it easier to write custom HTTP clients
which are compatible across all HTTP servers. It will hopefully
make migrating between different Rack servers easier for new
projects.
* Ruby 1.8 support removed. Ruby 1.9.3 is currently the earliest
supported version. However, expect minor, likely-unnoticeable
performance regressions if you use Ruby 2.1 or earlier. Going
forward, Rainbows! will favor the latest version (currently 2.2) of
the mainline Ruby implementation, potentially sacrificing
performance on older Rubies.
New features:
* sd_listen_fds(3) emulation added for systemd compatibility.
You may now stop using PID files and other process monitoring
software when using systemd.
* Newly-set TCP socket options are now applied to inherited sockets.
* Dynamic changes in the application to Rack::Utils::HTTP_STATUS
hash is now supported; allowing users to set custom status lines
in Rack to be reflected in unicorn. This feature causes a minor
performance regression, but is made up for Ruby 2.2 users with
other optimizations.
* The monotonic clock is used under Ruby 2.1+, making the
timeout feature immune to system clock changes.
As Rainbows! may be used anonymously without registration, the
project is committed to supporting anonymous and pseudonymous
help requests, contributions and feedback via plain-text mail to:
rainbows-public@bogomips.org
The mail submission port (587) is open to those behind firewalls
and allows access via Tor and anonymous remailers.

and mirrored to various other places, so you do not even need

* [PATCH 1/5] http_parser: handle keepalive_requests internally

unicorn 5 dropped support for this, essentially allowing unlimited
persistent connections if we used the parser as-is.
Since most of our concurrency models cannot handle infinite
persistent connections without being vulnerable to DoS,
we must support keepalive_requests like nginx does.

Only passes tests (using unicorn 4.x) so far. There is likely
more to do, but just publishing these changes early to give
folks some time to look at them over the weekend.
