The Tunnelblick tun/tap drivers worked fine on Montery and Ventura, but don't work after upgrade to Sonoma (14.1.1). Any drivers soon?

This is the first I've heard about problems with the tun/tap system extensions on Sonoma.

Have you followed the instructions in Installing Kexts on an M1 Mac Running macOS Big Sur 11.1 or later? I assume you would need to re-install the kexts after upgrading to Sonoma.

The extensions won't be updated unless someone posts enough information to find out why they don't work on Sonoma. (And maybe not even then – see The Future of Tun and Tap VPNs on macOS.)

What would be the alternative?
I've just tried to install Tunnelblick on a Mac Mini M2 with Sonoma 14.1.1
I've installed the kexts but no dice.
