To make up for the lack of new hints today, you could review all 473 10.5 hints, in case you missed some over the last few months. Or if you're really feeling motivated, you could browse the entire database of hints (11,300+) from oldest to newest, then test and comment on every hint's 10.5 compatibility :).
We'll return as usual tomorrow, of course.
