* Time#to_s(:rfc822) uses #formatted_offset instead of unreliable and non-standard %z directive #1899 [Zachary Zolton]
* Make TimeWithZone#to_formatted_s an alias to TimeWithZone#to_s #1796 [Levin Alexander]
* Introduce Array.wrap(foo) to wrap the argument in an array unless it's already an array. Wraps nil as an empty array. Use instead of Array(foo) and foo.to_a since they treat String as Enumerable. [Jeremy Kemper]
