+* TimeZone#to_s uses UTC rather than GMT; reapplying change that was undone in [8679]. #1689 [Cheah Chu Yeow]
+
 * Time.days_in_month defaults to current year if no year is supplied as argument #10799 [Radar], uses Date.gregorian_leap? to determine leap year, and uses constant lookup to determine days in month [Geoff Buesing]  
 
 * Adding Time and DateTime #compare_with_coercion, which layers behavior on #<=> so that any combination of Time, DateTime and ActiveSupport::TimeWithZone instances can be chronologically compared [Geoff Buesing]
