Changes in Drupal 8.3 break the tests for Private Taxonomy. It does not appear possible to fix the problem without breaking the tests for Drupal 8.2. So this branch is for Drupal >=8.3.
With the exception of Apache Solr integration the port of Private Taxonomy to Drupal 8 is complete. However, there still seem to be more than normal changes to the underlying dependencies that break things. It is expected these should settle down fairly quickly.
