+== Version 0.3.21 (tzdata v2010j) - 28-May-2010
+
+* Updated to tzdata version 2010j
+  (http://article.gmane.org/gmane.comp.time.tz/3225).
+* Change invalid timezone check to exclude characters not used in timezone
+  identifiers and avoid 'character class has duplicated range' warnings with
+  Ruby 1.9.2.
+* Ruby 1.9.2 has deprecated "require 'rational'", but older versions of
+  Ruby need rational to be required. Require rational only when the Rational
+  module has not already been loaded.
+* Remove circular requires (now a warning in Ruby 1.9.2). Instead of using
+  requires in each file for dependencies, tzinfo.rb now requires all tzinfo
+  files. If you were previously requiring files within the tzinfo directory
+  (e.g. require 'tzinfo/timezone'), then you will now have to
+  require 'tzinfo' instead.
