Version 1.3.30 (in progress)
============================

09/20/2006: wsfulton
            Fix %ignore on director constructors

09/20/2006: wsfulton
            Fix seg faults and asserts when director methods are ignored (#1543533)

09/20/2006: wsfulton
            Fix out of source builds - bug #1544718

09/20/2006: olly
	    [ALL] Templates can now be instantiated using negative numbers and
	    constant expressions, e.g.:

	    template<int q> class x {};
	    %template(x_minus1) x<-1>;
	    %template(x_1plus2) x<1+2>;

09/20/2006: olly 
	    [ALL] Treat a nested class definition as a forward declaration rather
	    than ignoring it completely, so that we generate correct code for
	    passing opaque pointers to the nested class (fixes SF bug #909387).

09/20/2006: olly 
            *** POTENTIAL INCOMPATIBILITY ***
	    [php] Overload resolution now works.  However to allow this, SWIG
	    generated wrappers no longer coerce PHP types (which reverts a change
	    made in 1.3.26).  So for example, if a method takes a string, you
	    can no longer pass a number without explicitly converting it to a
	    string in PHP using: (string)x

09/18/2006: mgossage
            [ALL] fix on swiginit.swg, has been reported to crash on several test cases
	    found and fixed problem in imports under python (mingw)

09/16/2006: wsfulton
            [Python] Patch from Michal Marek for Python 2.5 to fix 64 bit array indexes on
            64 bit machines.

09/13/2006: wsfulton
            The explicitcall feature has been scrapped. This feature was introduced primarily
            to solve recursive director method calls. Director upcall improvements made instead:

            [Python, Ruby, Ocaml] The swig_up flag is no longer used. The required mutexes
            wrapping this flag are also no longer needed. The recursive calls going from C++
            to the target language and back again etc are now avoided by a subtlely different
            approach. Instead of using the swig_up flag in each director method to indicate 
            whether the explicit C++ call to the appropriate base class method or a normal
            polymorphic C++ call should be made, the new approach makes one of these calls
            directly from the wrapper method.

            [Java, C#] The recursive call problem when calling a C++ base class method from
            Java/C# is now fixed. The implementation is slightly different to the other languages
            as the detection as to whether the explicit call or a normal polymorphic call is made
            in the Java/C# layer rather than in the C++ layer.

09/11/2006: mgossage
            [ALL] updated swiginit.swg to allow multiple interpreters to use multiple
	    swig modules at once. This has been tested in Lua (mingw & linux),
	    perl5 & python (linux) only.

09/11/2006: mgossage
            [lua] added support for passing function pointers as well as native lua object
            into wrappered function.
            Added example funcptr3 to demonstrate this feature

09/05/2006: olly
	    [php] Rename ErrorCode and ErrorMsg #define-s to SWIG_ErrorCode
	    and SWIG_ErrorMsg to avoid clashes with code the user might be
	    wrapping (patch from Darren Warner in SF bug #1466086).  Any
	    user typemaps which use ErrorCode and/or ErrorMsg directly will
	    need adjusting - you can easily fix them to work with both old
	    and new SWIG by changing to use SWIG_ErrorMsg and adding:

		#ifndef SWIG_ErrorMsg
		#define SWIG_ErrorMsg() ErrorMsg()
		#endif

08/29/2006: olly
	    [php] Move constant initialisation from RINIT to MINIT to fix a
	    warning when using Apache and mod_php.  We only need to create
	    PHP constants once when we're first initialised, not for every HTTP
	    request.

08/21/2006: mgossage
            [Lua]
	    Bugfix #1542466 added code to allow mapping Lua nil's <-> C/C++ NULL's
	    updated various typemaps to work correctly with the changes
	    added voidtest_runme.lua to show the features working

08/19/2006: wuzzeb (John Lenz)
	    [Guile] Add feature:constasvar to export constants as variables instead of functions
            that return the constant value.

08/11/2006: wsfulton
            [Java] DetachCurrentThread calls have been added so that natively created threads
            no longer prevent the JVM from exiting. Bug reported by Thomas Dudziak and
            Paul Noll.

08/10/2006: wsfulton
            [C#] Fix director protected methods so they work

07/25/2006: mutandiz
	    [allegrocl]
	    more additions to std::string, some tweaks and small bug fixes
	    -nocwrap mode.

07/21/2006: mgossage
            [Lua]
	    Bugfix #1526022 pdated std::string to support strings with '\0' inside them
	    updated typemaps.i to add support for pointer to pointers

07/19/2006: mutandiz
	    [allegrocl]
	    - Add std_string.i support.
	    - Add newobject patch submitted by mkoeppe (thanks!)
	    - Fix type name mismatch issue for nested type definitions.
	      specifically typedefs in templated class defns.

07/18/2006: mgossage
	    Bugfix #1522858
	    updated lua.cxx to support -external-runtime command

07/14/2006: wuzzeb (John Lenz)
	    Increment the SWIG_RUNTIME_VERSION to 3, because of the
	    addition of the owndata member in swig_type_info.
	    Reported by: Prabhu Ramachandran

07/05/2006: wsfulton
            Search path fixes:
            - Fix search path for library files to behave as documented in Library.html.
            - Fix mingw/msys builds which did not find the SWIG library when installed.
            - Windows builds also output the mingw/msys install location when running
              swig -swiglib.
            - The non-existent and undocumented config directory in the search path has
              been removed.

07/05/2006: wsfulton
            Fix $symname special variable expansion.

07/04/2006: wuzzeb (John Lenz)
	    [Chicken]
	    Add %feature("constasvar"), which instead of exporting a constant as a
	    scheme function, exports the constant as a scheme variable.  Update the
	    documentation as well.

07/04/2006: wsfulton
            [See entry of 09/13/2006 - explicitcall feature and documentation to it removed]
            New explicitcall feature which generates additional wrappers for virtual methods
            that call the method explicitly, not relying on polymorphism to make the method
            call. The feature is a feature flag and is enabled like any other feature flag.
            It also recognises an attribute, "suffix" for mangling the feature name, see
            SWIGPlus.html#SWIGPlus_explicitcall documentation for more details.

            [Java, C#]
            The explicitcall feature is also a workaround for solving the recursive calls
            problem when a director method makes a call to a base class method. See
            Java.html#java_directors_explicitcall for updated documentation.

06/28/2006: joe (Joseph Wang)
	    [r] Initial support for R

06/20/2006: wuzzeb (John Lenz)
	    [Chicken]
            Minor fixes to get apply_strings.i testsuite to pass
	    Remove integers_runme.scm from the testsuite, because SWIG and Chicken does
            handle overflows.

06/17/2006: olly
	    [php] Added some missing keywords to the PHP4 keyword list, and
	    fixed __LINE__ and __FILE__ which were in the wrong category.
	    Also added all the keywords new in PHP5, and added comments
	    noting the PHP4 keywords which aren't keywords in PHP5.

06/17/2006: olly
	    [php] Don't segfault if PHP Null is passed as this pointer (e.g.
	    Class_method(Null)) - give a PHP Error instead.
	    
06/15/2006: mutandiz
	    [allegrocl]
	    Add initial support for std::list container class.
	    Fix a few bugs in helper functions.

05/13/2006: wsfulton
            [Java] Replace JNIEXPORT with SWIGEXPORT, thereby enabling the possibility
            of using gcc -fvisibility=hidden for potentially smaller faster loading wrappers.

05/13/2006: wsfulton
            Fix for Makefiles for autoconf-2.60 beta

05/13/2006: wsfulton
            Vladimir Menshakov patch for compiling wrappers with python-2.5 alpha.

05/12/2006: wsfulton
            Fix buffer overflow error when using large %feature(docstring) reported
            by Joseph Winston.

05/12/2006: wsfulton
            [Perl] Operator overload fix from Daniel Moore.

05/25/2006: mutandiz
	    [allegrocl]
	    Fix bug in generation of CLOS type declarations for unions
	    and equivalent types.

05/24/2006: mutandiz
	    [allegrocl]
	    Don't require a full class definition to generate a CLOS wrapper.

05/20/2006: olly
	    [php] GCC Visibility support now works with PHP.

05/19/2006: olly
	    [php] Removed support for -dlname (use -module instead).  Fixed
	    naming of PHP extension module to be consistent with PHP
	    conventions (no "php_" prefix on Unix; on PHP >= 4.3.0, handle Unix
	    platforms which use something other than ".so" as the extension.)

05/13/2006: wsfulton
            [C#] Director support added

05/07/2006: olly
	    [php] Don't segfault if PHP Null is passed where a C++ reference
	    is wanted.

05/05/2006: olly
	    [php] Fix wrappers generated for global 'char' variables to not
	    include a terminating zero byte in the PHP string.

05/03/2006: wsfulton
            Modify typemaps so that char * can be applied to unsigned char * or signed char *
            types and visa versa.

05/03/2006: efuzzyone
	    [cffi]Thanks to Luke J Crook for this idea.
             - a struct/enum/union is replaced with :pointer only if
               that slot is actually a pointer to that type. So,: 
                    struct a_struct { int x; } and
                    struct b_struct { a_struct struct_1; }; 
               will be converted as:
                   (cffi:defcstruct b_struct
                           (struct_1 a_struct))
             - Other minor fixes in lispifying names.

05/02/2006: wsfulton
            Fix possible redefinition of _CRT_SECURE_NO_DEPRECATE for VC++.

04/14/2006: efuzzyone
	    [cffi]
            Thanks to Thomas Weidner for the patch.
            - when feature export is set (export 'foo) is 
              generated for every symbol
            - when feature inline is set (declaim (inline foo)) is 
              generated before every function definition
            - when feature intern_function is set 
              #.(value-of-intern-function "name" "nodeType" package)
              is emitted instead of the plain symbol. A sample swig-lispify 
              is provided.
            - every symbol is prefixed by it's package.

04/13/2006: efuzzyone
	    [cffi]
	    Fixed the generation of wrappers for global variables. 
            Added the option [no]swig-lisp which turns on/off generation 
            of code for swig helper lisp macro, functions, etc.
