Rails 2.1 and default setting of Partial updates

I just updated to 2.1 and created a new, empty project. According to the docs I've seen, including:

http://ryandaigle.com/articles/2008/4/1/what-s-new-in-edge-rails-partial-updates

The file config/initializers/new_rails_defaults.rb has the default setting for partial updates and just needs to be edited: "Note: There’s currently a config/initializers/new_rails_defaults.rb file that has this setting, so edit that file if you have it."

However, in the new_rails_defaults.rb file in my new empty project does not have that setting in it (ActiveRecord::Base.partial_updates = ...)

Yeah, I can add it, but I thought it should already be in there?

Thanks, jt

It was enabled by default in Active Record just before 2.1 launch.

Check ActiveRecord::Base.partial_updates in script/console to verify.
