What is cx_Freeze? cx_Freeze is a set of scripts and modules for freezing Python scripts into executables, in much the same way that py2exe and py2app do. Unlike these two tools, cx_Freeze is cross platform and should work on any platform that Python itself works on. It supports Python 2.3 or higher, including Python 3. Where do I get it? http://cx-freeze.sourceforge.net What's new? The release notes can be read here as well: http://cx_freeze.readthedocs.org/en/latest/releasenotes.html 1) Added support for Python 3.4. 2) Added hooks for PyQt4, PyQt5 and PySide to handle their plugins. 3) Added support for creating a shortcut/alias to the Applications directory within distributed DMG files for OS X. 4) Improve missing modules output. 5) Avoid polluting the extension module namespace when using the bootstrap module to load the extension. 6) Added support for using setuptools and pip if such tools are available. 7) Added first tests; nose and mock are required to run them. 8) Remove --bundle-iconfile in favor of --iconfile as a more generic method of including the icon for bdist_mac. 9) Documentation improved and FAQ added. 10) Converted samples to follow PEP 8. Bugs fixed: * cxfreeze-quickstart failed if the default base was not used * scripts frozen with Python 3 fail with an ImportError trying to import the re module * fix bug where after a first attempt to find a module failed, the second attempt would erroneously succeed * stop attempting to load a module by a name that is not a valid Python identifier
