I was just reading about Gems/Plugin development for Rails 3 and ran across this post that says that alias_method_chain is no longer used. I can see the method is still there in activesupport-3.0.0/lib/active_support/core_ext/module/aliasing.rb.
Should I still be using alias_method_chain in Rails 3?
Is this still reflective of the best practices for gems/plugins in Rails 3 that want to modify ActiveRecord?
