Rails 3.0.11

Hi everyone,

Rails 3.0.11 has been released. This is a patch-level release containing
bug fixes and an important security fix.

rails_xss plugin
Not Affected: Pre-3.0.0 releases, without the rails_xss plugin, did
no automatic XSS escaping, so are not considered vulnerable
Fixed Versions: 3.0.11, 3.1.2

Please see [the rubyonrails-security
