“The most noticeable new feature is that development mode got a ton and a half faster. Inspired by Active Reload, we now only reload classes from files you’ve actually changed. The difference is dramatic on a larger application.”
I was wondering if anybody knew where I could start looking to find the code that controls this behavior. I need to write some custom hooks for it.
