Hello All,

I am *extremely *pleased to be able to announce the version 0.4 release of
xdress.  This version contains much anticipated full support for Clang as a
parser!  This is almost entirely due to the efforts of Geoffrey Irving.
 Please thank him the next time you get a chance :)

This release also contains a lot of other goodies that you can read about
in the release notes below.

Happy Generating!

XDress 0.4 Release

XDress is a numpy-aware automatic wrapper generator for C/C++ written in
pure Python. Currently, xdress may generate Python bindings (via Cython)
for C++ classes, functions, and certain variable types. It also contains
idiomatic wrappers for C++ standard library containers (sets, vectors,
maps). In the future, other tools and bindings will be supported.

The main enabling feature of xdress is a dynamic type system that was
designed with the purpose of API generation in mind.

Release highlights:

   - Clang support! All kudos to Geoffrey Irving!
   - NumPy dtypes may be created independently of C++ STL vectors
   - A complete test suite refactor
   - Arbitrary source code locations
   - Global run control files
   - A plethora of useful bug fixes

This version of xdress is *not* 100% backwards compatible with previous
versions of xdress. We apologize in the name of progress. It represents ans
impressive 245 files changed, 44917 aggregate line insertions (+), and 7893
deletions (-).

Download the code from GitHub: http://github.com/xdress/xdress

XDress is free & open source (BSD 2-clause license) and requires Python
2.7+, NumPy 1.5+, Cython 0.19+, and optionally Clang, GCC-XML, pycparser,
dOxygen, or lxml.
 New Features<http://xdress.org/previous/0.4_release_notes.html#new-features>
Clang Support<http://xdress.org/previous/0.4_release_notes.html#clang-support>

Through the herculean efforts of Geoffrey Irving xdress finally has full,
first-class Clang/LLVM support! This is major advancement as it allows
xdress to wrap more modern versions of C++ than GCC-XML can handle. Because
of deficiencies in the existing libclang and Python bindings it was
necessary for us to fork libclang for xdress in the short term. We hope to
integrate these changes upstream. Clang versions 3.2 - 3.4 are supported.
Independent NumPy

In previous versions of xdress, to create a dtype of type T the user needed
to declare the desire for a wrapper of an STL vector of type T. These two
desires have now been separated. It is now possible to create a dtype via
the dtypes run control parameter. STL vectors are still wrapped via dtypes.
See the dtypes module for more information.
Shiny New Test Suite<http://xdress.org/previous/0.4_release_notes.html#shiny-new-test-suite>

The xdress test suite has been completely revamped to include both unit and
integration tests which are run for all available parsers. The integration
tests are accomplished though two fake projects - cproj and cppproj - on
which the xdress CLI is run. These tests are now fully platform
independent, unlike the previous BASH-based test suite.
Source Paths<http://xdress.org/previous/0.4_release_notes.html#source-paths>

Source file paths are now given by either their absolute or relative path.
This allows source code to be located anywhere on the user's file system
and enable the wrapping of dependencies or externally supplied libraries as
needed. The run control parametersourcedir has been deprecated.
Global Run Control

It is sometimes useful to be able to set system-wide run control
parameters. XDress will now search the following files in order of
increasing precedence.

   - $HOME/.xdressrc
   - $HOME/.xdressrc.py
   - $HOME/.config/xdressrc
   - $HOME/.config/xdressrc.py

$HOME is the user's home directory. Settings in the project run control
file take precedence over the values here.
 Major Bug Fixes<http://xdress.org/previous/0.4_release_notes.html#major-bug-fixes>

   - Debug file now always written when in debug mode.
   - STL sets of custom types now allowed.
   - Template parameters now allowed to be enum values.
   - Allow classes with no default constructor.
