I think I made a boo-boo

I agree!

bind=noabstract
$ xpra version
5.0.7-r0

Don't buy into the fear mongering about abstract sockets.
And don't use noabstract with a version that doesn't know what it means.
Abstract sockets are a v6 feature: #4098

[stdedos]

... can we go back in publishing https://xpra.org/beta/focal/main/binary-amd64/ builds? 🙏

I feel like that's where I'd find the v6 builds for focal.

... or there is some versioning I'm unaware?

[stdedos]

... finally I know why I don't live on the bleeding edge 😅
