-It is recommended to install Sinatra on Ruby 1.8.7, 1.9.2, JRuby or Rubinius.
+== Requirement
 
 The following Ruby versions are officially supported:
 
-[ Ruby 1.8.6 ]
-  It is not recommended to use 1.8.6 for Sinatra. However, it will be
-  officially supported until Sinatra 1.3.0 is released. RDoc and CoffeeScript
-  templates are not supported by this Ruby version. 1.8.6 includes a major
-  memory leak in its Hash implementation, which is triggered by Sinatra
-  versions prior to 1.1.1. The current version explicitly prevents this leak
-  at the cost of performance. You will have to downgrade Rack to 1.1.x, as
-  Rack >= 1.2 no longer supports 1.8.6.

 [ Ruby 1.8.7 ]
   1.8.7 is fully supported, however, if nothing is keeping you from it, we
   recommend upgrading to 1.9.2 or switching to JRuby or Rubinius.
