Don't upgrade BI to 4.6.4.7 (unstable). 4.6.4.8 is out and okay

+1 here. Can we access the older builds somewhere? I'd like to roll back one, but didn't have system restore on before the update.
 
Nobody has uploaded the previous build that I know of. Ken told me he found a crash bug occurring when there are web requests (e.g. a mobile app or web client connected to Blue Iris). I would expect that to be patched within an hour.
