On behalf of the Python development community and the Python
3.5 release team, I'm pleased to announce the availability of
Python 3.5.0b1. 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 1; these were granted exceptions
to the freeze, and are scheduled to be added before beta 2.)
This is a preview release, and its use is not recommended for
Three important notes for Windows users about Python 3.5.0b1:
- If you have previously installed Python 3.5.0a1, you may
need to manually uninstall it before installing Python
- If installing Python 3.5.0b1 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.
