Mailman 3 April 2015 - Python-announce-list

ANNOUNCING: GNU Mailman 3.0
by Barry Warsaw April 28, 2015

April 28, 2015

I am very happy to announce the release of GNU Mailman 3.0. Over seven years in development, Mailman 3 represents a major new version, redesigned as a suite of cooperating components which can be used to mix and match however you want. The core engine is now backed by a relational database and exposes its functionality to other components via an administrative REST+JSON API. Our new web user interface, Postorius is Django-based, as is our new archiver HyperKitty. The core requires Python 3.4 while Postorius and HyperKitty require Python 2.7. We also have a library called mailman.client, which works in both Python 2 and 3 and is the official Python bindings to the core's REST API. The mailman- bundler is a set of scripts that help building out a complete Mailman 3 system in Python virtual environments. There are tons of new features. See the detailed official announcement at https://mail.python.org/pipermail/mailman-announce/2015-April/000210.html What is GNU Mailman? GNU Mailman is free software for managing electronic mail discussion and e-newsletter lists. Mailman is integrated with the web, making it easy for users to manage their accounts and for list owners to administer their lists. Mailman supports built-in archiving, automatic bounce processing, content filtering, digest delivery, and more. Mailman 3 is released under the terms of the GNU General Public License, version 3. See the release notes, as well as links to download each component: http://wiki.list.org/Mailman3 You probably want to start with the bundler and let it grab and install all the other parts. More information is available at: http://www.list.org http://wiki.list.org http://launchpad.net/mailman #mailman on freenode mailman-developers(a)python.org Happy Mailman Day, -The Mailman Cabal Abhilash, Aurélien, Barry, Florian, John, Mark, Stephen, Sumana, and Terri

[RELEASED] Python 3.5.0a4 is now available
by Larry Hastings April 20, 2015

April 20, 2015

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. You can find Python 3.5.0a4 here: https://www.python.org/downloads/release/python-350a4/ Happy hacking, //arry/
