phpBB 3.1 Alpha2 Preview Release

Posted by naderman in Development with the tags on November 21st, 2013

We’re happy to announce the immediate availability of the second preview release of the upcoming phpBB 3.1, codenamed Ascraeus.

This preview release is targeted at phpBB developers and advanced users who wish to assist us with this very important testing phase. We do not recommend, and will not support, running this version in a live production environment.

As with previous releases we compiled a list of feature and bugfix highlights on our wiki. Most note-worthily Alpha2 ships with a new responsive version of prosilver optimised for handheld devices which we introduced in previous blog posts. Based on feedback from extension authors we have additionally made a number of changes to the extension system to better accomodate the different needs extensions have.

There are a number of known issues with this release which will be fixed in upcoming versions. It is currently impossible to upgrade from 3.0 to 3.1 on Microsoft SQL Server and the redirect() function does not work correctly from within (extension) controllers.

Please use this release for testing purposes only. As always, we will provide no support for upgrading until the RC stage and urge users not to use testing releases in a production site. Please help us by reporting any bugs you find via a ticket on our tracker.

Unstable packages are available on Area51 at Information on moving from 3.0 to 3.1 (currently only for testing purposes) is available at

Please note that phpBB 3.1 has some requirements that differ from phpBB 3.0:

  • PHP version 5.3.3 or greater
  • PHP’s json extension
  • Only PostgreSQL versions 8.3 and above are supported
