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.

* nntp://news.public-inbox.org/inbox.comp.lang.ruby.rainbows

and mirrored to various other places, so you do not even need
to use a valid address when posting.

unicorn 5 will only support Ruby 1.9.3 and later, so remove
some checks for Hash#compare_by_identity and IO.copy_stream
which we know exist in Ruby 1.9.
Favor &:sym proc dispatch to avoid unnecessary captures and
bytecode size increases, too.
Finally, ensure we fail fast by converting some literal
hashes to use non-arrow syntax for symbolic keys.

A few more odds and ends before 5.0 (sometime next week).
I'll do some more testing later, but overall keeping this up-to-date
with the latest developments in unicorn isn't as bad as I thought it'd
be.
5 more changes:
tiny bytecode reductions for cold paths
Ruby 1.9.3+-only cleanups
response: avoid garbage string entirely
revactor: remove fcntl dependency
response: simplify regexp
