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

10/29/2006: wsfulton
            [Java] Remove DeleteLocalRef from end of director methods for now as it is causing a
            seg fault when run on Solaris 8.

10/29/2006: wuzzeb (John Lenz)
	    [Guile] Patch from Chris Shoemaker to clean up some warnings in the generated code.

10/29/2006: wsfulton
            [Java] Important fix to prevent early garbage collection of the Java proxy class
            while it is being used in a native method. The finalizer could destroy the underlying
            C++ object while it was being used. The problem occurs when the proxy class is no
            longer strongly reachable after a native call.  The problem seems to occur in
            memory stress situations on some JVMs. It does not seem to occur on the
            Sun client JVM up to jdk 1.5. However the 1.6 client jdk has a more aggressive garbage
            collector and so the problem does occur. It does occur on the Sun server
            JVMs (certainly 1.4 onwards). The fix entails passing the proxy class into the native
            method in addition to the C++ pointer in the long parameter, as Java classes are not
            collected when they are passed into JNI methods. The extra parameter can be suppressed
            by setting the nopgcpp attribute in the jtype typemap to "1" or using the new -nopgcpp
            commandline option.

            See Java.html#java_pgcpp for further details on this topic.

10/24/2006: wsfulton
            [C#] Fix smart pointer wrappers. The virtual/override/new keyword is not generated
            for each method as the smart pointer class does not mirror the underlying pointer
            class inheritance hierarchy. SF #1496535

10/24/2006: mgossage
            [lua] added support for native methods & member function pointers.
            fixed test cases arrays_dimensionless & cpp_basic. Added new example (functor).
            tidied up a little of the code (around classHandler).

10/17/2006: wsfulton
            [C#, Java] directorout typemap changes to fall in line with the other director
            languages. $result is now used where $1 used to be used. Please change your typemaps
            if you have a custom directorout typemap.

10/18/2006: wsfulton
            Some fixes for applying the char array typemaps to unsigned char arrays.

10/17/2006: wsfulton
            [C#, Java] Add in const size_t& and const std::size_t& typemaps.

10/15/2006: efuzzyone 
            [CFFI] Suppress generating defctype for enums, thanks to Arthur Smyles. Patch 1560983. 

10/14/2006: wuzzeb (John Lenz)
            [Chicken] Minor fix to make SWIG work with the (as yet unreleased) chicken 2.5

            [Guile,Chicken] Fix SF Bug 1573892.  Added an ext_test to the test suite to test
            this bug, but this test can not really be made generic because the external code must
            plug into the target language interpreter directly.
            See Examples/test-suite/chicken/ext_test.i and ext_test_external.cxx

            Added a %.externaltest to common.mk, and any interested language modules can
            copy and slightly modify either the chicken or the guile ext_test.i

10/14/2006: mgossage
            [Lua] added OUTPUT& for all number types, added a long long type
            fixed several test cases.
            update: changed typemaps to use SWIG_ConvertPtr rather than SWIG_MustGetPointer
            started spliting lua.swg into smaller parts to make it neater

10/13/2006: wsfulton
            [C#, Java] Marginally better support for multiple inheritance only in that you can
            control what the base class is. This is done using the new 'replace' attribute in the 
            javabase/csbase typemap, eg in the following, 'Me' will be the base class,
            no matter what Foo is really derived from in the C++ layer.

              %typemap(javabase, replace="1") Foo "Me";
              %typemap(csbase, replace="1") Foo "Me";

            Previously it was not possible for the javabase/csbase typemaps to override the C++ base.

10/12/2006: wsfulton
            [Java] Remove potential race condition on the proxy class' delete() method 
            (it is now a synchronized method, but is now customisable by changing the 
            methodmodifier attribute in the the javadestruct or javadestruct_derived typemap)

            [C#] Remove potential race condition on the proxy class' Dispose() method, 
            similar to Java's delete() above.

            *** POTENTIAL INCOMPATIBILITY ***

10/12/2006: wsfulton
            [Ruby, Python] Remove redundant director code in %extend methods (%extend
            methods cannot be director methods)

10/12/2006: wsfulton
            [Ruby, Python] Fix #1505594 - director objects not returned as director objects
            in %extend methods.

10/11/2006: wsfulton
            [Java] Fix #1238798 - Directors using unsigned long long or any other type
            marshalled across the JNI boundary using a Java class (where the jni typemap 
            contains jobject).

10/06/2006: wsfulton
            Fix #1162194 - #include/%include within a structure

10/06/2006: wsfulton
            Fix #1450661, string truncation in String_seek truncating Java/C# enums.

10/06/2006: mgossage
            [Lua] Fix #1569587. The name is now correct.

10/04/2006: wsfulton
            Director fixes for virtual conversion operators

10/04/2006: olly
	    [php] Fix #1569587 for PHP.  Don't use sizeof() except with string
	    literals.  Change some "//" comments to "/* */" for portability.

10/04/2006: mgossage
            [Lua] Partial Fix #1569587. The type is now correct, but the name is still not correct.

10/03/2006: wsfulton
            [Ruby] Fix #1527885 - Overloaded director virtual methods sometimes produced
            uncompileable code when used with the director:except feature.

10/03/2006: wsfulton
            Directors: Directors are output in the order in which they are declared in 
            the C++ class rather than in some pseudo-random order.

10/03/2006: mmatus
            Fix #1486281 and #1471039.

10/03/2006: olly
	    [Perl] Fix for handling strings with zero bytes from Stephen Hutsal.

09/30/2006: efuzzyone
            [CFFI] Bitfield support and vararg support due to Arthur Smyles.
            C expression to Lisp conversion, thanks to Arthur Smyles for the initial
            idea, it now supports conversion for a whole range of C expressions. 

09/28/2006: wsfulton
            Fix #1508327 - Overloaded methods are hidden when using -fvirtual optimisation.
            Overloaded methods are no longer candidates for elimination - this mimics
            C++ behaviour where all overloaded methods must be defined and implemented
            in a derived class in order for them to be available.

09/25/2006: wsfulton
            [Ruby, Python, Ocaml] Fix #1505591 Throwing exceptions in extended directors

09/25/2006: wsfulton
            Fix #1056100 - virtual operators. 

09/24/2006: olly
	    Don't accidentally create a "<:" token (which is the same as "[" in C++).
	    Fixes bug # 1521788.

09/23/2006: olly
	    [Ruby] Support building with recent versions of the Ruby 1.9
	    development branch.  Fixes bug #1560092.

09/23/2006: olly
	    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>;

	    Also, constant expressions can now include comparisons (>, <, >=,
	    <=, !=, ==), modulus (%), and ternary conditionals (a ? b : c).

	    Fixes bugs #646275, #925555, #956282, #994301.

09/22/2006: wsfulton
            Fix %ignore on director methods - Bugs #1546254, #1543533

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
	    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.
