With yesterday's release of Drupal 8 RC 1, we're pressing ahead quickly with a version of aGov for Drupal 8. We've just completed the port of the aGov 3 theme, and plan to have a release on https://www.drupal.org/project/agov by the end of October.
This will mean that Government organisations looking to move to Drupal 8 will be able to do so with the ease of installing a regular aGov site.
As part of the release, we'll be running a beta program for anyone that wants to test the release and be involved in structured feedback sessions, so please sign up via https://agov.com.au/updates
This is open to any Government web teams or Drupal development firms looking to fast track their use of Drupal 8 for their own clients.
