[ANN] Rainbows! 5.0.0 - Rack HTTP server for the sleepy

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

Those URLs still work, but new URLs work over HTTPS, too:

(Getting rid of many subdomains to reduce subjectAltName bloat

And NNTP:

(NNTPS is planned for news.public-inbox.org, at least)

Anyways, the 5.0.0 release was the last I'll announce on
ruby-talk. I'm no longer promoting this project (not that I
really promote anything, ever), but will continue to support it
as long as anybody uses it.

You are more than welcome to use a fake identity and anonymous
remailers if you're too embarrased to admit you're using it,
even!
