+Version 2.2.0 (in Erlang/OTP R13B04)
+------------------------------------
+ - Much better support for opaque types (thanks to Manouk Manoukian).
+ - Added support for recursive types (experimental).
+ - Added support for parameterized modules.
+ - Dialyzer now warns when -specs state that a function returns some type
+ when in fact it does not.
+ - Added --no_native (-nn) option so that the user can bypass the native code
+ compilation that dialyzer heuristically performs when dialyzing many files.
+ - Fixed minor bug in the dialyzer script allowing the --wx option to bring
+ up the wx-based GUI regardless of its placement in the options list.
+ - Options --apps and -Wrace_conditions, which were added in the previous
+ version, are now properly documented in the manual.

Version 2.1.0 (in Erlang/OTP R13B03)

- Dialyzer can statically detect some kinds of data races in Erlang programs.
Use the new option -Wrace_conditions to enable the race analysis.
