SteamDB has spotted a weekend update for the game:
Size is ~100 MB (with Workshop Tools installed). More info will be edited in if available.
A reminder has been added in to advise participants in the Overwatch program
to focus specifically on the conduct of the player you've been assigned to watch, even if there are other players in the game showing questionable behavior. Specifically, "Other players in this match may be reviewed by other Overwatchers. Focus your attention on the hero displayed above."
Internally, the game can now flag bulk combat log requests
