A security update for games played in Local Network mode. It’s marked important because it closes ways another device on the classroom Wi-Fi could slow down or interfere with a game in progress, so please install it before your next class.
One device can’t freeze the game. A device sending a flood of join attempts — wrong PINs, or joins after you’ve locked the roster — could tie up QuizBlast badly enough to stall your controls and the projector. Those attempts are now turned away without slowing the game, and a device that keeps trying is held back for a moment. Students joining normally won’t notice anything.
Only the game’s own pages can reach it. The small web server QuizBlast runs on your Mac now answers only the address shown on your projector, so a web page from somewhere else can’t send requests to your game. Students should join with that address or the QR code, as always. If someone types your Mac’s name instead (the one ending in .local), they’ll now see a blank page or an error page instead of the join screen.
Tidier connections. Browser connections left open with nothing happening are closed after half a minute, so they don’t pile up during a long class. Students’ games aren’t interrupted.
Cloud mode games aren’t affected by any of this.
