I'm happy to announce version 8.x-1.0-beta2 of the Acquia Purge module for Drupal 8, the second release in the private beta phase. Progress is good and we have seen the first technical challenges on a few clients, leading to further improvements in this release. This version depends on purge8.x-3.0-beta7 and won't work without it, so please update to 8.x-3.0-beta7.
