Materia v11.0.1

v11.0.1 is our first post-Django patch release to address a number of minor bugs and issues associated with v11.

LTI 1.3 Improvements

While Materia would always submit the highest score for a particular widget instance and course context, if a different score was submitted instead of the score for a given play session, this difference was not communicated to the user. Materia now tracks the value submitted in the LtiPlayState model, and informs the user about the submission delta on the score screen.

Performance Improvements

The /performance endpoint of the widget instance API has been notoriously heavy. We've introduced a new composite index to the LogPlay model to speed it up considerably.

Update Guidance and Database Migration

This update will require a migration to the Materia database. For more information about updating your Materia instance and migrating the database, review our Versioning and Updating documentation page.
