Added
- Background color of infobox is configurable for exams & tasks
- Tasks add the maximum number of claimants
Fixed
- The same exam & task can't be assigned to the same user again after it's completed #266
- The problem that the current value of the upload torrent count indicator in the assessment & task may decrease.
- Can't buy medals again after expiration
- The problem that the downhash parameter in the torrent download link is too short and can be exhaustively enumerated, thus leaking the passkey #281
For the torrent increment count indicator in exam & task, if the data is not correct after updating, it is recommended to delete the user's exam and reassign it.
