Next signed release of win pv drivers?

[Håkon Alstadheim <hakon@xxxxxxxxxxxxxxxxxx>]

I've tried upgrading windows pv drivers to 9.0.0 several times, but the 
bug in the start-up, which causes windows to not find the new (or old) 
drivers keeps hitting me. There may be a sequence of installation that 
allows upgrades to work, but I have not found it.
I have tried a development build after this was fixed, and they work, 
but I'd really like a properly signed set of drivers. Any idea when to 
expect the next signed release ?
