About a month ago in r235 we implemented a whole new mechanism for offline support using Service Worker. This currently only affects Chrome and Firefox, but it's a pretty big change to a major feature. We're due a stable release soon and although my own tests with it worked, I've not really heard any feedback about this since.
I assume no news is good news (nobody's noticed it's broken so far), but it would be useful to get some positive feedback too. So has anyone tried running their game offline with r235 and did it work OK? If this is important to you and you haven't tested it yet, I'd appreciate if you could try re-exporting with the latest beta and check offline support still works the way you want it too.
Thanks!
