Version 1.3.25 (In progress)
============================

02/21/2005: wsfulton
            [PHP] Patch from Olly Betts, so that wrappers compile with Zend thread safety enabled.

02/17/2005: wsfulton
            Memory leak fix in some of the scripting language modules when using default
            arguments in constructors. The scripting language was not taking ownership of the
            C++ object memory when any of the constructors that use default arguments was called.

02/16/2005: wsfulton
            SF #1115055: Failed make install. Patch from Rob Stone.

02/16/2005: wsfulton
            [Java] SF #1123416 from Paul Moore. Correct memory allocation for STRINGARRAY
            typemaps in various.i.

02/15/2005: wsfulton
            Disabled typemap search changes for now (see entry 19/12/2004). It breaks
            old typemaps, lengthens the execution time by about 25% and introduces
            inconsistencies.

02/15/2005: wsfulton
            swig -help follows other software by printing to stdout instead of stderr now.
            swig -version also displays to stdout instead of stderr now.
            Behaviour reported by Torsten Landschoff.

02/15/2005: wsfulton
            [Ruby] Fix for the less commonly used ordering of %include and #include, so
            that the generated code compiles. Bug reported by reported by Max Bowsher.
              %include foo.h
              %{
              #include foo.h
              %} 

02/15/2005: wsfulton
            [C#, Java] SWIG_exception macro will now return from unmanaged code / native code
            as soon as it is called. Fixes possible JVM crashes and other code unexpectedly
            being executed. Note SWIG_exception is only occasionally used by SWIG library
            writers, and is best avoided by SWIG users.

02/15/2005: wsfulton
            [C#, Java] Typemaps can now be targeted at global variable names
            and static member variable names. Previously the typemaps for 
            the setters were ignored, for example:

              %typemap(in) int globalint "..."
              int globalint;

02/13/2005: mkoeppe (Matthias Koeppe)
	    [Guile] Add %typecheck for SWIGTYPE, add %typecheck for ptrdiff_t, fix
	    typemaps for size_t.

	    [Pike] Merge patch from Torsten Landschoff for improved Pike configuration.

02/12/2005: mkoeppe (Matthias Koeppe)
	    New configure switches --without-tcl, --without-python etc. allow to
            disable the search for installed languages.

01/31/2005: wuzzeb (John Lenz)
            - Add DohSortList to DOH
	    
	    - Improve the runtime type system:
               + Speed. Type loading is now O(n log n) instead of O(N^2), which
	         for large modules is a huge improvement.
               + A whole bunch of functions in swigrun.swg no longer need the 
                 swig_type_list_handle passed to them.  The only one left is 
		 TypeQuery.  This also makes runtime.swg a lot smaller.
	       + Split up swig_type_info structure into two structures
	         (swig_type_info and swig_cast_info)
	       + Store a pointer to a swig_type_info rather than just the type
	         name string in the linked list of casts. First off, this makes
	         the guile module a little faster, and second, the
	         SWIG_TypeClientData() function is faster too. 
	       + Add the idea of a module into the type system.  Before, all the
	         types were stored in one huge linked list. Now, another level is
	         added, and the type system stores a linked list of modules, each
	         of which stores an array of types associated with it.
	       + For more information of how the runtime type system now works,
	         please see Doc/Manual/typemaps.html and Doc/Devel/runtime.txt
		 
	    - Update all language modules to use the new type system.  The changes
	      to each language module are minor.  All languages are now able to
	      use runtime.swg for external access to the type system.  Before
	      only python and perl did.

	    - [guile, mzscheme, ocaml, and php4]  These languages opened up the
	      init function inside the .cxx code, and any code in the .swg files
	      in the init section was inside this function.  This was a problem
	      for swiginit.swg, which needs to be inserted before the SWIG_init
	      function is opened.  Thus I changed these languages to be like
	      python or perl, where the init function is declared in the .swg
	      file.
	      
	    - [Ruby] Instead of moving the init function to the .swg file, I
	      added a new section initbeforefunc, and then added
	      %insert(initbeforefunc) "swiginit.swg"

	    - [MzScheme] Fix enums and fix Examples/Makefile.in so that if
	      multiple -I arguments are specified in the INCLUDES variable, each
	      gets a ++ccf.

	    - [Guile GH] Update Guile GH to use the new type system.  See
	      Doc/Manual/Guile.html for how smobs are now used.

01/11/2005: wsfulton
            [C#] New typemap called 'csconstruct'. The code in this typemaps was previously hard
            coded and could not be customised by a user. This typemap contains the code that is
            generated into a proxy class's constructor.

            [Java] New typemap called 'javaconstruct'. The code in this typemaps was previously hard
            coded and could not be customised by a user. This typemap contains the code that is
            generated into a proxy class's constructor. Another typemap named 'javaconstruct_director'
            is used instead when the proxy class is a director class.

            [C#, Java] If a C++ class did not have a default constructor, a protected default constructor
            was automatically generated by SWIG. This seems is unnecessary and has been removed
            and thereby giving the user almost complete control over the generated code along with the
            new typemaps above.

19/12/2004: mmatus
            [Disabled, see entry 02/15/2004]
            - Fix typemap search, now the "out" typemap search is done as follows

                 int *Foo::foo(int bar)   ->  int *Foo::foo(int bar)
                                          ->  int *Foo::foo
                                          ->  int *foo(int bar)
                                          ->  int *foo
                                          ->  int *

               then, now you can be more specific, and define

              /* apply only for  'Foo::foo' method */
              %typemap(out) int * Foo::foo(int *bar) ...; 

              /* apply for all 'foo' functions/methods */
              %typemap(out) int * foo(int *bar) ...; 

              %inline {
                struct Foo {
                   int *foo(int *bar);
                };
              }
	  

15/12/2004: mmatus
            - More fixes for templates and template default args.
              See template_default.i for scary cases that now are 
              supported, besides the already ugly STL/std cases.
              
            - Cosmetics and more use of 'const' where it was implicit.
            - Other fixes for OSS, which is now working again with 1.3.25.
