Buffered logs in Rails 3.2.1

I just upgraded my first application to Rails 3.2.1. It's been pretty smooth which I appreciate. However I have noticed that my production log is now buffered. It use to flush on every response but now it does not. I would like to restore the previous behavior bug I have not found any information on how to do so. If anyone knows how to do this I would appreciate hearing it.

Thank you.
