 # CHANGES
 
+## Jellyfish 0.4.0 -- 2012-10-14
+
+* Now you can define your own custom controller like:
+
+``` ruby
+require 'jellyfish'
+class Heater
+  include Jellyfish
+  get '/status' do
+    temperature
+  end
+
+  def controller; Controller; end
+  class Controller < Jellyfish::Controller
+    def temperature
+      "30\u{2103}\n"
+    end
+  end
+end
+use Rack::ContentLength
+use Rack::ContentType, 'text/plain'
+run Heater.new
+```
+
+* Now it's possible to use a custom matcher instead of regular expression:
+
+``` ruby
+require 'jellyfish'
+class Tank
+  include Jellyfish
+  class Matcher
+    def match path
+      path.reverse == 'match/'
+    end
+  end
+  get Matcher.new do |match|
+    "#{match}\n"
+  end
+end
+use Rack::ContentLength
+use Rack::ContentType, 'text/plain'
+run Tank.new
+```
+
+* Added a Sinatra flavor controller
+
+``` ruby
+require 'jellyfish'
+class Tank
+  include Jellyfish
+  def controller; Jellyfish::Sinatra; end
+  get %r{^/(?<id>\d+)$} do
+    "Jelly ##{params[:id]}\n"
+  end
+end
+use Rack::ContentLength
+use Rack::ContentType, 'text/plain'
+run Tank.new
+```
+
