The Aegir team is very pleased to announce the official release of Aegir 3.0. This release ships with significant stability improvements, Drush 6 and 7 support, improved SSL, subdirectory multisite and nginx support and much, much more!
This release marks the deprecation of the 2.x branch. We will continue to provide security releases through the end of 2015. All Aegir users are strongly encouraged to upgrade to the 3.0 release. The upgrade has been thoroughly tested and has worked reliably for us.
Upgrading from Aegir 2.x moves Aegir from a Drupal 6 platform to a Drupal 7 one. The Debian package will migrate the front-end for you. While we have tested this with Aegir core, we strongly recommend disabling any contributed modules you may be running.
We have a very dynamic community of contrib developers, and various projects built atop Aegir. So if you were waiting for Aegir 3 to be stable, easy to install and production-ready, now is the time. The 3.x branch will be well supported as a lot of shops are running it in production already.
The front-end has been ported to Drupal 7. We've also raised the minimum Drush version to 6.x, and the Debian package now installs Drush via Composer. Drush 7 is also supported.
We've added several "Golden contrib" modules to the distribution:
Hosting Remote Import
Hosting Site Backup Manager
Hosting Tasks Extra
We're planning to add additional well-supported contrib modules over the course of the Aegir 3.x lifecycle. Along similar lines, we've removed hosting_platform_pathauto, as it's built-in now.
We've introduced initial Drupal 8 support, though this is still a work-in-progress. This mostly depends on Drupal 8 and Drush 8 stabilizing, before we'll be able to more fully manage Drupal 8 sites.
Aegir 3 now supports SNI for SSL.
A number of significant bug fixes and stability improvements have been incorporated. Among them, we've added locking in our task queue, and improved backup reliability significantly.
