The beta used to be updated a few times a month and went silent back in April. Any ideas as to why this would happen?
Perhaps they're working on a larger update. Maybe 'Sketch Cloud', no more versions, no more App Store, just teh subscriptions!!1
They just released a small update. Maybe they noticed this thread ;-)
A month ago, I saw this link a few times on twitter and DN. Seems to be an online sketch viewer. Maybe they're focussing on this instead of their main Sketch app...
