Ruby on Rails 3.2 is released. It can speed up your application cause it only reloads classes that actually changed.

I also currently divide my projects under "vendor/plugins" to get a better overview. This is now marked as deprecated and will be removed in Rails 4. After the upgrade i got a lot of deprecation warnings from my crons. So i added the following to the "config/application.rb" file on the production machine:

ActiveSupport::Deprecation.silenced = true

After that you have some time to fix these deprecations.
