CHANGELOG.md

 # Changelog
 
+## 2.7
+Features:
+* Account deletion: Users can now delete their own accounts. Admins can delete
+  any user account. Account deletion removes sessions and their contents created
+  by the user and anonymizes data created through participation in other
+  sessions.
+* Auto-deletion: Accounts can be deleted automatically after a configurable
+  period of inactivity.
+* OpenID Connect: OIDC is now supported for authentication. Configuration
+  discovery support is required.
+
+Improvements:
+* Public Session Pool: Added API endpoint to clone a session from the pool.
+  Previously, cloning had to be performed by the client.
+
+Bug fixes:
+* Import/Export: The handling of session features during import has been fixed.
+  The raw exported data can now be imported without further manipulation by the
+  client.
+
+**This version is brought to you by:**
