Hello friends of Mailman!

I said I played this song so many times before
That the melody keeps repeating

Time for my usual "sneak one in before the new year" release! I'm happy to announce the third beta release of the core Mailman 3.0 engine. Mailman 3.0b3 is code named "Here Again".

You can download GNU Mailman 3.0b3 from Launchpad or the Python Cheeseshop:

The GNU Mailman documentation is available online at:

Here's a summary of the most user and developer visible changes:

• Python 2.7 is now required. Python 2.6 is no longer officially supported.

• The canonical resource for a mailing list in the REST API now uses its list-id by default instead of its posting address. For backward compatibility, you can still reference a mailing list by its posting address. However the list-id is more stable since it will not change.

• REST API change: The JSON representation for held messages has changed to a more flat representation.

• You can now specify a list style to use when creating a mailing list through the REST API.

• The subject_prefix attribute of mailing lists can be get/set through the REST API. Thanks to Terri Oda.

• Membership change moderation (subscriptions and unsubscription requests) are available through the REST API.

• list_id is added to the JSON representation for a mailing list. Thanks to Jimmy Bergman.

• User resources are expanded in the REST API. You can change a user's display name or password, and you can now verify their password through REST by posting the plain text password and checking the HTTP response code.

• Addresses can now be verified and unverified through the REST API.

• Some changes have been made to the configuration file format.

  • [passlib]path is renamed to [passlib]configuration
  • [mta]configuration names a separate file to configure Postfix
  • The default style is now called legacy-default, and a legacy-announce style has been added. You can select the system default style through via the [styles]default configuration.

• More database schema cleanups, in both the ban table and the mailinglist table.

• Changes in the options for the bin/mailman aliases command.

• Lots of other bug fixes.

Enjoy, and Happy New Year, -Barry
