=== Rainbows! 5.0.0 - maintained as long as anybody uses it! / 2015-11-25 00:58 UTC

  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.
