Version 3.0.0 (16 Mar 2014)
===========================
2014-03-16: wsfulton
C++11 support initially developed as C++0x support by Matevz Jekovec as a Google Summer of Code
project has been further extended. The C++11 support is comprehensive, but by no means complete
or without limitations. Full details for each new feature in C++11 is covered in the
CPlusPlus11.html chapter in the documentation which is included in SWIG and also available
online at http://www.swig.org/Doc3.0/CPlusPlus11.html.

[Lua] Numerous Lua improvements:
1. %nspace support has been added. Namespaces are mapped to tables in the module, with the same
name as the C++ namespace.
2. Inheritance is now handled differently. Each class metatable keeps a list of class bases instead
of merging all members of all bases into the derived class.
3. The new metatables result in differences in accessing class members. For example:
%module example
struct Test {
enum { TEST1 = 10, TEST2 = 20 };
static const int ICONST = 12;
};
Now this can be used as follows:
print(example.Test.TEST1)
print(example.Test.ICONST)
The old way was:
print(example.Test_TEST1)
print(example.Test_ICONST)
4. The special class metatable member ".constructor" was removed. Now SWIG generates the proxy
function by itself and assigns it directly to the class table "__call" method.
5. eLua should also now support inheritance.
6. 'const' subtable in eLua is considered deprecated.
Changes in behaviour:
a. You can no longer assign to non-existing class members in classes without a __setitem__ method.
It will cause a Lua error.
b. You can no longer iterate over a module table and copy everything into the global namespace.
Actually, this was never the case, but it is now explicitly prohibited.
c. Now changing a base class will immediately affect all derived classes.
d. There might be some issues with inheritance. Although the bases iteration scheme is the same
as was used for merging base classes into derived one, some unknown issues may arise.
The old metatable behaviour can be restored by using the -no-old-metatable-bindings option.

[Python] Change in default behaviour wrapping C++ bool. Only a Python True or False
will now work for C++ bool parameters. This fixes overloading bool with other types.
Python 2.3 minimum is now required for wrapping bool.
When wrapping:
const char* overloaded(bool value) { return "bool"; }
const char* overloaded(int value) { return "int"; }
Previous behaviour:
>>> overloaded(False)
'int'
>>> overloaded(True)
'int'
>>> overloaded(0)
'int'
Now we get the expected behaviour:
>>> overloaded(False)
'bool'
>>> overloaded(0)
'int'
The consequence is when wrapping bool in non-overloaded functions:
const char* boolfunction(bool value) { return value ? "true" : "false"; }
The previous behaviour was very Pythonic:
>>> boolfunction("")
'false'
>>> boolfunction("hi")
'true'
>>> boolfunction(12.34)
'true'
>>> boolfunction(0)
'false'
>>> boolfunction(1)
'true'
Now the new behaviour more along the lines of C++ due to stricter type checking. The
above calls result in an exception and need to be explicitly converted into a bool as
follows:
>>> boolfunction(0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: in method 'boolfunction', argument 1 of type 'bool'
>>> boolfunction(bool(0))
'false'
The old behaviour can be resurrected by passing the -DSWIG_PYTHON_LEGACY_BOOL command line
parameter when executing SWIG. Typemaps can of course be written to customise the behaviour
for specific parameters.

Fix SF Bug #1363 - Problem with method overloading when some methods are added by %extend
and others are real methods and using template default parameters with smart pointers.
This is noticeable as a regression since 2.0.12 when using the default smart pointer
handling for some languages when the smart pointer wraps std::map and other STL containers.

[Python] SF Patch #346 from Jens Krueger. Correct exception thrown attempting to
access a non-existent C/C++ global variable on the 'cvar' object. The exception thrown
used to be a NameError. However, as this access is via a primary, an AttributeError
is more correct and so the exception thrown now is an AttributeError. Reference:
http://docs.python.org/2/reference/expressions.html#attribute-references

[Python] Patch #143 Fix type shown when using type() to include the module and package
name when using -builtin.
2014-03-01: wsfulton
[Python] SF patch #347 Fix missing argument count checking with -modern.
Fixes regression introduced when builtin changes were introduced in SWIG-2.0.3.
2014-02-21: wsfulton
[PHP] Fix warning suppression using %warnfilter for PHP reserved class names.
2014-02-19: olly
[Lua] Add keyword warnings for Lua keywords and Basic Functions.
2014-02-19: olly
-Wallkw now includes keywords for all languages with keyword
warnings (previously Go and R were missing).
2014-02-19: olly
[PHP] Update the lists of PHP keywords with new ones from PHP 5.4
and newer (and some missing ones from 5.3). Reserved PHP constants
names are now checked against enum values and constants, instead
of against function and method names. Built-in PHP function names
no longer match methods added by %extend. Functions and methods
named '__sleep', '__wakeup', 'not', 'parent', or 'virtual' are no
longer needlessly renamed.
2014-02-15: wsfulton
Fix the %$ismember %rename predicates to also apply to members added via %extend.
Add %$isextendmember for %rename of members added via %extend. This can be used to
distinguish between normal class/struct members and %extend members. For example
'%$ismember, %$not %$isextendmember' will now identify just class/struct members.

[Python] Patch #137 - fix crashes/exceptions in exception handling in Python 3.3
2014-02-15: wsfulton
[Java] Add support for the cdata library.
2014-02-08: vkalinin
Nested class support added. This primarily allows SWIG to properly parse nested
classes and keep the nested class information in the parse tree. Java and C#
have utilised this information wrapping the C++ nested classes as Java/C#
nested classes. The remaining target languages ignore nested classes as in
previous versions. Help is needed by users of these remaining languages to
design how C++ nested classes can be best wrapped. Please talk to us on the
swig-devel mailing list if you think you can help.
Previously, there was limited nested class support. Nested classes were treated
as opaque pointers. However, the "nestedworkaround" feature provided a way to
wrap a nested class as if it was a global class. This feature no longer exists
and is replaced by the new "flatnested" feature. This effectively does the same
thing with less manual code to be written. Please see the 'Nested classes'
section in the documentation in SWIGPlus.html if you were previously using this
feature.
SWIG now parses the contents of nested classes where previously it did not. You
may find that you will need to make adjustments to your interface file as
effectively extra code is being wrapped.

[Guile] Patch #133. Make scm to string conversion work with non-ascii strings.
Guile 2 has a completely rewritten string implementation. SWIG made some assumptions
that are no longer valid as to the internals of guile's string representation.
2014-01-30: wsfulton
[C#] Add new swigtype_inout.i library containing SWIGTYPE *& OUTPUT typemaps.
Example usage wrapping:
void f(XXX *& x) { x = new XXX(111); }
would be:
XXX x = null;
f(out x);
// use x
x.Dispose(); // manually clear memory or otherwise leave out and leave it to the garbage collector

[Go] Add %go_import directive.

[Go] Add support for Go 1.3, not yet released.
2014-01-20: wsfulton
Director exceptions (Swig::DirectorException) now derive from std::exception
and hence provide the what() method. In Python and Ruby, this replaces the now
deprecated DirectorException::getMessage() method.
2014-01-14: diorcety
Patch #112 - Fix symbol resolution involving scopes that have multiple levels
of typedefs - fixes some template resolutions as well as some typemap searches.
2014-01-11: wsfulton
Fix and document the naturalvar feature override behaviour - the naturalvar
feature attached to a variable name has precedence over the naturalvar
feature attached to the variable's type. The overriding was not working
when turning the feature off on the variable's name.
Fix so that any use of the naturalvar feature will override the global
setting. Previously when set globally by -naturalvar or %module(naturalvar=1),
use of the naturalvar feature was not always honoured.

[Go] Fix bug that broke using directors from a thread not
created by Go.

[Python] SF Bug #1297
Resolve several issues related to python imports.
For example, it's now possible to import modules having the same module
names, but belonging in different packages.
From the user's viewpoint, this patch gives a little bit more control on
import statements generated by SWIG. The user may choose to use relative
or absolute imports.
Some details:
- we (still) generate import statements in the form 'import a.b.c' which
corresponds to absolute imports in python3 and (the only available)
ambiguous one in python2.
- added -relativeimport option to use explicit relative import syntax
(python3),
The "Python Packages" section in the documentation discusses how to work
with importing packages including the new -relativeimport command line option.

[Octave, Perl, Python, R, Ruby, Tcl] Change the length of strings created from fixed-size char
buffers in C code.
This is a potential backwards compatibility break: a "char buf[5]" containing "ho\0la" was
returned as a string of length 5 before, but is returned as a string of length 2 now. Also,
it was possible to assign a (non-NUL-terminated) string "hello" to such a buffer before but
now this fails and only "helo" can fit.
Apply "char FIXSIZE[ANY]" typemaps to explicitly choose the old behaviour.

[Perl] Add support for directors.
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).

[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.
