Anti-Cheating [#anti-cheating]

* Submission similarity checks strengthened: reordered or lightly-modified copies of previously submitted agents are more likely to be flagged at submit time.

Scoring [#scoring]

* Fixed a bug that could let per-problem score statistics return stale values to the race scorer when the same problem was being updated concurrently.
