2.0 released!
The Aegir team is very pleased to announce the official release of Aegir 2.0.0. This long-awaited release ships with significant stability improvements, Drush 5 and 6 support, subdirectory multisite support, improved nginx support, native views and much, much more! We unfortunately had to drop support for Drupal 5, as Drush 5 and 6 dropped support for this unsupported Drupal release.
This release deprecates the 1.x branch, marking the 1.11 release as the last one of the 1.x branch. All Aegir users are strongly encouraged to upgrade to the 2.0 release. The upgrade has been thoroughly tested and works fairly reliably, except some documented minor issues.
We have a very dynamic community of contrib developers, and various projects built atop Aegir. So if you were waiting for Aegir 2 to be stable, easy to install, production-ready, now is the time. The 2.x branch will be well supported as a lot of shops are running it in production already.
See the release notes for more details!
