On behalf of the Python development community and the Python 3.5 release team, I'm thrilled to announce the availability of Python 3.5.0a4. Python 3.5.0a4 is the fourth and alpha release of Python 3.5, which will be the next major release of Python. Python 3.5 is still under development, and is not yet complete. This is a preview release, and its use is not recommended for production settings. The next release of Python 3.5 will be 3.5.0b1, the first beta release. Python 3.5 will enter "feature freeze" at this time; no new features will be added to 3.5 after this point. Python 3.5.0b1 is scheduled to be released May 22, 2015. Three important notes for Windows users about Python 3.5.0a4: * If you have previously installed Python 3.5.0a1, you may need to manually uninstall it before installing Python 3.5.0a4 (issue23612). * If installing Python 3.5.0a4 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 installer for Python 3.5. In addition to the conventional installer and the web-based installer, Python 3.5 now has an embeddable installer designed to be run as part of a larger application's installer for apps using or extending Python.
