Jan 1, 2026January 2026: Delivered a feature enhancement for PrairieLearn to randomize distractors in the pl-order-blocks component, introducing a new distractor-order option while preserving the overall solution structure and backward compatibility. The work included a refactor of the distractor randomization logic into a modular function, adopting Pythonic patterns (for loops, enumerate, itertools) to improve readability and maintainability, and updating tests/docs to reflect the change. This sets the stage for more dynamic item construction and easier future enhancements without impacting existing configurations or assessments.
