My laptop is on metered Internet, now, and low on disk space, so
installing pandoc is too expensive.
There's also dozens of incompatible Markdown flavors out there,
most of which don't really handle manpages.
Updating the website now requires olddoc 1.8.0 (which is much
smaller than pandoc), but I'm the only one with that burden. On
the flipside more users can update and read the manpages locally
without extra software, since nearly every developer's *nix

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.

project is committed to supporting anonymous and pseudonymous
help requests, contributions and feedback via plain-text mail to:

Rainbows! 4.6.2 - see you on the other side
This release updates documentation to reflect the migration of the
mailing list to a new public-inbox[1] instance. This is necessary
due to the impending RubyForge shutdown on May 15, 2014.
The public-inbox address is: rainbows-public@bogomips.org
(no subscription required, plain text only)
ssoma[2] git archives: git://bogomips.org/rainbows-public
browser-friendly archives: http://bogomips.org/rainbows-public/
As evidenced by our git history, Rainbows! development has stagnated
over the years. Rainbows! was designed to be an unopinionated
exploration into various concurrency options offered in the Ruby
ecosystem.
In recent years, I have come to favor the one-shot-based,
worst-of-all-worlds design of yahns: http://yahns.yhbt.net/README
Without the exploration from Rainbows!, yahns may not exist today.
Disclaimer: Rainbows! has always been intolerant of buggy/broken code in
libraries and apps. yahns is even less tolerant of buggy/broken code,
as the SIGKILL-based timeout mechanism inherited unicorn is completely
gone. On the other hand, yahns has reasonable defaults so you do not
have to read documentation to configure it.
