Version 3.0.0 (in progress)
============================

2013-12-18: ianlancetaylor
	    [Go] Don't require that Go environment variables be set
	    when running examples or testsuite when using Go 1 or
	    later.

2013-12-17: ianlancetaylor
	    [Go] Remove -longsize option (for backward compatibility,
	    ignore it if seen).

2013-12-17: ianlancetaylor
	    [Go] Add -go-pkgpath option.

2013-12-16: ianlancetaylor
	    [Go] Update for Go 1.2 release.  Add support for linking
	    SWIG code directly into executable, rather than using a
	    shared library.

2013-12-13: ianlancetaylor
	    [Go] Add SWIG source file name as comments in generated
	    files.  This can be used by Go documentation tools.

2013-12-12: jleveque
	    [Lua] Fix typo (wchar instead of wchar_t) which made wchar.i
	    for Lua useless.

2013-12-12: vmiklos
	    [PHP] PHP's peculiar call-time pass-by-reference feature was
	    deprecated in PHP 5.3 and removed in PHP 5.4, so update the REF
	    typemaps in phppointers.i to specify pass-by-reference in the
	    function definition.  Examples/php/pointer has been updated
	    accordingly.

2013-12-12: olly
	    [PHP] The usage of $input in PHP directorout typemaps has been
	    changed to be consistent with other languages.  The typemaps
	    provided by SWIG have been updated accordingly, but if you
	    have written your own directorout typemaps, you'll need to
	    update $input to &$input (or make equivalent changes).

            *** POTENTIAL INCOMPATIBILITY  ***

2013-11-27: vadz
            [C#, Java, Python] Add std_auto_ptr.i defining typemaps for returning std::auto_ptr<>.

2013-11-09: wsfulton
            [C#] Apply patch #79 from Brant Kyser
              - Remove using directives from the generated C# code and fully qualify the use of all .NET
                framework types in order to minimize potential name collisions from input files defining
                types, namespace, etc with the same name as .NET framework members.
              - Globally qualify the use of .NET framework types in the System namespace
              - Remove .NET 1.1 support, .NET 2 is the minimum for the C# module

            This is a potential backwards compatibility break if code has been added relying on these using
            statements that used to be generated:

              using System;
              using System.Runtime.InteropServices;

            The quick fix to add these back in is to add the -DSWIG2_CSHARP command line option when
            executing SWIG. See CSharp.html documentation for more info.

2013-10-17: wsfulton
