 What's New?
 ===========
-The most notable changes since SWIG1.1 include the following:

+SWIG-1.3.x offers a huge number of improvements over older SWIG-1.1 releases.
+These improvements include:
 
    - Support for C++ overloaded functions and methods.
-
    - Support for C++ smart pointers.
-
    - Support for C++ namespaces
-
    - Support for C++ overloaded operators.
-
-   - Support for C++ templates including member templates,
-     specialization, and partial specialization.
-
+   - Support for C++ templates including member templates.
+   - Support for C++ template specialization and partial specialization.
    - Parsing support for almost all C/C++ datatypes.
-
-   - A full C preprocessor with macro expansion.
-     Includes C99 variadic macro support.
-
+   - Automatic translation of C++ exception specifiers.
+   - Contract support.
+   - A full C preprocessor with macro expansion. Includes C99 variadic macros.
    - Java, Ruby, MzScheme, PHP4, OCAML, Pike, CHICKEN, XML and C# modules
      added.  Guile module improved.
-
    - Director support - upcalls for C++ virtual functions into the target 
      language proxy class.
-
    - Better code generation.   SWIG is better able to make optimizations
      in order to generate less code.
-
    - Testing framework part of the distribution ("make -k check" support).
-
    - A lot of minor bug fixes and cleanup.
-
    - Better Windows support.
 
 If you used SWIG-1.1, a number of old features are missing from SWIG-1.3.

+Users of OS X should be aware that Darwin handles shared libraries and linking in
