Site should be running normally again. I switched to HTTPS a while ago and the transition wasn’t so smooth. In the process a configuration change made the spam filter eat most comments. I’ve dug them out from the spam folder, hope I didn’t miss any. Sorry about it!
Preview 4 will be up shortly but it will mainly contain bug fixes and stability improvements. Squatted some bugs that had been reported in the meantime – some of them a bit tough.
