+=== Rainbows! 4.0.0 - MOAR concurrency for MOAR COARS / 2011-06-27 09:33 UTC
+
+  Rainbows! now scales to more than 1024 worker processes without
+  special privileges.  To enable this, Rainbows! now depends on
+  Unicorn 4.x and thus raindrops[1].
+
+  client_max_header_size directive is added to limit per-client
+  memory usage in headers.
+
+  An experimental StreamResponseEpoll concurrency option now
+  exists to buffer outgoing responses without any thread-safe
+  dependencies.  Unlike the rest of Rainbows! which works fine
+  without nginx, this concurrency option is /only/ supported
+  behind nginx, even more strongly so than Unicorn itself.
+  non-nginx LAN clients are NOT supported for this.  This relies
+  on the sleepy_penguin[2] RubyGem (and Linux).
+
+  There are some minor bug fixes and cleanups all around.  See
+  "git log v3.4.0.." for details.
