activesupport/CHANGELOG

 *Edge*
 
+* require 'active_support' no longer orders the whole menu of core extensions. Ask for just what you need: e.g. require 'active_support/core/time' to use timezones, durations, and stdlib date/time extensions. [Jeremy Kemper]
+
 * Removed rarely-used DRb cache store.  [Jeremy Kemper]
 
 * TimeWithZone.name returns 'Time', to further thwart type checking [Geoff Buesing]
