rails/activesupport/CHANGELOG.md

• Support rfc2822 format for Time#to_fs & Date#to_fs.

  Akshay Birajdar

• Optimize load time for Railtie#initialize_i18n. Filter I18n.load_paths passed to the file watcher to only those under Rails.root. Previously the watcher would grab all available locales, including those in gems which do not require a watcher because they won't change.

  Nick Schwaderer

• Add a filter option to in_order_of to prioritize certain values in the sorting without filtering the results by these values.

  Igor Depolli

• Improve error message when using assert_difference or assert_changes with a proc by printing the proc's source code (MRI only).

  Richard Böhme, Jean Boussier

• Add a new configuration value :zone for ActiveSupport.to_time_preserves_timezone and rename the previous true value to :offset. The new default value is :zone.

  Jason Kim, John Hawthorn
