    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.

  • v2.6.0 protected
    790558e3 · Release version 2.6.0 ·
    Release version 2.6.0
    
    Features:
    * Experimental support for CouchDB 2 has been added. Note: The data
      migration script is not compatible with CouchDB 2 and has to be run
      before an upgrade.
    
    Improvements:
    * Error handling and logging has been improved. It should now be easier
      to find the cause of problems. API error responses now contain the
      name of the `Exception` which caused the error. Further details for
      debugging purposes can be enabled with the new
      `api.expose-exception-messages` setting (Do NOT enable in production
      environments!).
    * Updated OAuth handling to restore compatibility with 3rd-party login
      services.
    
    Bug fixes:
    * Fixed multiple bugs caused by incorrect type handling in the database
      layer.
    * Fixed XFO header check behind reverse proxy (used by clients when
      embedding external websites).
    * Fixed rounding error in learning progress calculation.
    * Fixed `security.cors.origins` setting.
    * Fixed import of data from older versions.
    
    Security:
    * Fixed DoS vulnerability in authentication handling behind reverse
      proxy.
    
    Configuration changes:
    Minor changes to the web server and Tomcat proxy configuration are
    required (see [installation guide](src/site/markdown/installation.md)).
