+
+ARA 0.16.6 is a maintenance release for users that are not yet using ARA 1.x.
+
+Changes since 0.16.5:
+
+- Fixed web application crash due to encoding/decoding of binary non-ascii
+  content in task results
+- The [sqlite middleware](https://ara.readthedocs.io/en/stable-0.x/advanced.html)
+  was adapted to support running under gunicorn as well as mod_wsgi
+- ``python -m ara.setup.env`` now returns commands that use bash expansion to
+  take into account existing environment variables
+
+## Eventual end of life for ARA 0.x
+
+All new feature and development effort for more than a year has been spent on
+the master branch of ARA which is the basis of version 1.x releases.
+
+In fact, 0.x and 1.x are vastly different code bases at this point.
+They are diverging by more than 400 commits and 1.x features a completely
+re-written backend which includes many new features, notably a new REST API.
+
+Users are encouraged to try the latest release of ARA, currently [1.2.0](https://ara.recordsansible.org/blog/2019/11/06/announcing-the-release-of-ara-records-ansible-1.2/),
+and create issues on [GitHub](https://github.com/ansible-community/ara/issues)
+if they encounter any problems or missing features.
+
+ARA 0.16.6 could be the last release of ARA 0.x if no major issues are found.
