Not sure when the VPN was fixed, but it's really good news.
I won't switch to the latest build if the VPN is broken, but it's a bit surprising as it sounded like there was just a call screen fix.
When I got the VPN working above, I had about 5 domains being managed by the VPN. Just now I added another one, and then the VPN failed to connect. I tried about 4 or 5 times, and it failed every time. The error doesn't say anything about 'too many domains', but that appears to be the problem. When I delete the extra domain (well actually I deleted another domain) the VPN started working again.
