A teacher can now send notifications during a test to all test takers.

We've added a 'custom' release option for tests, so teachers can choose what parts of a test they release: score / students' answers / score per questions / solutions.

When grading a test, we now color the breadcrumb of unanswered questions (gray) differently from incorrectly answered questions (red).

We've updated the enumeration of exercises in the course material tab, so that it better reflects the numbers that students see in their breadcrumbs when practicing a package.

We've added a class setting for teachers to enable the calculator during practice.

We've added a new exercise type for chemistry called drawing molecules. It let's the student answer in the form of a molecule drawing and support feedback and automatic evaluation of the answer based on the Simplified molecular-input line-entry system (SMILES).

We've added the evaluation types eval_rational_functions and fb_rational_functions with automated feedback

We updated the exercise mistakes analysis view for exercises (via the wrench icon in the Info tab), to always show the mistakes in a pop up.

We've improved the feedback to authors when entering unavailable options in a Definition field for multiple choice questions.

We've added the fields undefined functions and allow long variables to the play api endpoint.

We fixed a bug where saving a feedback rule with a feedback template did not work.

We've added support for returning math markup in feedback for exercise type Python.

We've made sure that glossary words followed by the ; or the : character are now also picked up by the glossary.

We've made all javascript files load conditionally based on the exercise types used in a test.

We fixed a bug where, when solutions are hidden during practice, they were also hidden during teacher grading.
