Week of January 15-21, 2012

Lots of refactorings this week cleaned up the internals of ActionController and ActionView. Fortunately if you've been paying attention to deprecation warnings these should not have an impact on your applications when you upgrade to Rails 4.

• In a nice bit of tidying-up, 2c72f2a9 adds app/mailers to the list of things reported on by rake:stats.
• 5a6ea535 adds the ability to set config.actionview.logger independently of other loggers.
• number_to_percentage takes a :format option as of c0a3fe3c.
