Version 4.0.0 (in progress)
===========================

            [Java] #674 Add std_list.i to add support for std::list containers. The Java proxy
            extends java.util.AbstractSequentialList and makes the C++ std::list container look
            and feel much like a java.util.LinkedList from Java.

            [Python] Fix display of documented template types when using the autodoc
            feature. For example when wrapping:

              %feature("autodoc");
              template<typename X> struct T {};
              %template(TInteger) T<int>;

            the generated documentation contains:
              """Proxy of C++ T< int > class."""
            instead of:
              """Proxy of C++ T<(int)> class."""
            and
              """__init__(TInteger self) -> TInteger"""
            instead of
              """__init__(T<(int)> self) -> TInteger"""

	    [PHP] Update the OUTPUT Typemap to add return statement to the
	    PHP Wrapper.

2017-06-27: nihaln
	    [PHP] Update the enum and value examples to use the OO wrappers
	    rather than the flat functions produced with -noproxy.  There's
	    not been a good reason to use -noproxy for since PHP5 OO wrapping
	    was fixed back in 2005.

2017-06-23: m7thon
            [Python] fix and improve default argument handling:

            1. Fix negative octals. Currently not handled correctly by `-py3`
               (unusual case, but incorrect).
            2. Fix arguments of type "octal + something" (e.g. `0640 | 04`).
               Currently drops everything after the first octal. Nasty!
            3. Fix bool arguments "0 + something" (e.g. `0 | 1`) are always
               "False" (unusual case, but incorrect).
            4. Remove special handling of "TRUE" and "FALSE" from
               `convertValue` since there's no reason these have to match
               "true" and "false".
            5. Remove the Python 2 vs. Python 3 distinction based on the
               `-py3` flag. Now the same python code is produced for default
               arguments for Python 2 and Python 3. For this, octal default
               arguments, e.g. 0644, are now wrapped as `int('644', 8)`. This
               is required, as Python 2 and Python 3 have incompatible syntax
               for octal literals.

            Fixes #707

2017-06-21: futatuki
            #1004 - Fix ccache-swig executable name to respect configure's --program-prefix and
            --program-suffix values if used.

2017-06-21: tamuratak
            [Ruby] #911 - Add std::wstring support.

2017-06-19: wsfulton
            [Python] Fix handling of rich comparisons when wrapping overloaded operators:

              operator<  operator<=  operator>  operator>=  operator==  operator!=

            Previously a TypeError was always thrown if the type was not correct. NotImplemented
            is now returned from these wrapped functions if the type being compared with is
            not correct. The subsequent behaviour varies between different versions of Python
            and the comparison function being used, but is now consistent with normal Python
            behaviour. For example, for the first 4 operator overloads above, a TypeError
            'unorderable types' is thrown in Python 3, but Python 2 will return True or False.
            NotImplemented should be returned when the comparison cannot be done, see PEP 207 and
            https://docs.python.org/3/library/constants.html#NotImplemented

            Note that the bug was only present when overloaded operators did not also have a
            function overload.

            Fixes SF bug #1208 (3441262) and SF patch #303.

2017-06-16: wsfulton

            stdout at the same time.

2017-06-16: wsfulton
            [R] Fix wrapping function pointers containing rvalue and lvalue reference parameters.

2017-06-13: olly
	    [Perl] Fix testsuite to work without . in @INC - it was removed in
	    Perl 5.26 for security reasons, and has also been removed from
	    older versions in some distros.  Fixes
	    https://github.com/swig/swig/issues/997 reported by lfam.

2017-06-03: wsfulton
            Fix %import on a file containing a file scope %fragment forced inclusion to not
            generate the fragment contents as %import should not result in code being generated.
            The behaviour is now the same as importing code insertion blocks.
            Wrapping FileC.i in the following example will result in no generated code, whereas
            previously "#include <limits.h>" was generated:

              // FileA.i
              %fragment("<limits.h>", "header") %{
                #include <limits.h>
              %}

              %{
                #include <stdio.h>
              %}
              %fragment("<limits.h>");

              // FileC.i
              %import "FileA.i"
