Just browsing and in this blog: http://opensourceau.wordpress.com/2012/0...deigniter/
explain how to manage assets, but in the bottom of the blog, the writer write that the more secure way is to use assets helper, which i think in the forum said that it was not for CI 2.1.0, so my question is still how to manage assets in CI 2.1.0? did asset helper is already updated and can be used in CI 2.1.0
