-Version 2.3.0 (in Erlang/OTP R14)
----------------------------------
+Version 2.x.x (in Erlang/OTP R14B01)
+------------------------------------
+ - Fixed problems in the handling of remote types in records used as types
+ (thanks to Nico Kruber for the report and to Maria Christakis for the fix).
+ - Fixed handling of nested opaque types (thanks to Thorsten Schuett for

+Version 2.3.1 (in Erlang/OTP R14B)
+----------------------------------
+ - Eliminated warnings for auto-imported BIF clashes.
+
