Release v1.13.2, March 2022

Bug fixes:

• Fixed a crash in adding new deviations (e.g., personal deadline extensions) (unique constraint violation).
• Added an inspect link in the teacher's participant view so that it is faster to reach the inspect view for that student's submissions in that assignment.
• When submitting a file to an assignment fails because the file is too large, show a clear error message to the student.
• Fixed a crash in the submission list and inspect views when the submission has no submitters (i.e., when all submitters have been removed afterwards).

For system administrators and developers:

• There are small changes in the cache code and it is best to flush the caches (Memcached) in production after deploying this patch.
• Added a new A+ API endpoint for querying submission statistics: number of submissions and submitters.

  • https://plus.cs.aalto.fi/api/v2/exercises/EXERCISEID/statistics/
• Fixed issues in the sitemap (for Internet search engines like Google). Current courses have a higher priority in the sitemap.
• Added a rate limit for outgoing scheduled SIS enrollment requests to avoid throttling issues in the SIS API.
