On behalf of the Python development community and the Python 3.5 release team, I'm relieved to announce the availability of Python 3.5.0b2.  Python 3.5.0b1 had a major regression (see http://bugs.python.org/issue24285 for more information) and as such was not suitable for testing Python 3.5.  Therefore we've made this extra beta release, only a week later.  Anyone trying Python 3.5.0b1 should switch immediately to testing with Python 3.5.0b2.

Python 3.5 has now entered "feature freeze".  By default new features may no longer be added to Python 3.5.  (However, there are a handful of features that weren't quite ready for Python 3.5.0 beta 2; these were granted exceptions to the freeze, and are scheduled to be added before beta 3.)

This is a preview release, and its use is not recommended for production settings.

Three important notes for Windows users about Python 3.5.0b2:

• If installing Python 3.5.0b2 as a non-privileged user, you may need to escalate to administrator privileges to install an update to your C runtime libraries.
• There is now a third type of Windows build for Python 3.5.  In addition to the conventional installer and the web-based installer, Python 3.5 now has an embeddable release designed to be deployed as part of a larger application's installer for apps using or extending Python.  During the 3.5 alpha releases, this was an executable installer; as of 3.5.0 beta 1 the embeddable build of Python is now shipped in a zip file.
