Dear all,
These days, I've learned more about XSS and XSCF. So now, the two plugins have been patched to avoid these two kinds of attacks. Highly recommend to upgrade.
The onlinejudge assignment type now has the ability to "rejudge all". After updating the assignment settings (e.g. test cases and ratio of pe) which can affect grade, you can use this function to rejudge all submitted submissions.
Some minor bug fixes and UI improvement are also included. Wish you would like.
