Release v1.20.4, November 2023

Changes:

• Fixed missing informational messages in the 403 "forbidden/access restricted" error page. (#1247)
  • Due to an old bug, there were many cases where no visible informational message was shown in the 403 page even though the message had been defined in the source code for that specific case. The message explains the cause of the error to the user.
• A+ as LTI Tool v1.3: bug fixes
  • Do not send LTI grades to the Platform on non-LTI courses. (#1297)
  • Fixed crash when the LTI launch has expired from cache.
  • Added the course module's name to the module index page.
• Submitted PDF files are never rendered as plain text in the inspect submission page. (#1298)
• Very long submitted plain text files are loaded in chunks and improved the rendering performance for long files.
• Clarified the user interface messages about the visibility of the course module model answer chapter.
  • The previous messages always referred to the module deadline, but there are other alternative rules for the visibility than just the deadline.
• Fixed a bug in the visibility of the course module model answer chapter. (#1247)
  • When the course instance was public (visible without authentication) and the model answer chapter did not have any specific audience set, then unauthenticated users were able to view model answer chapters before they were supposed to be visible to any student.
