Tailscale stuck on v1.8.6

Help
1

I’m running Tailscale on NixOS 21.05, using this tailscale configuration, and everything works fine.

However, Tailscale is stuck on version 1.8.6, even though it appears to be up-to-date (v1.14.0) in nixpkgs.

I’ve run nixos-rebuild switch and rebooted multipled times, but no change. Anyone know why my version isn’t being updated?

~ (*) > tailscale --version
1.8.6
  go version: go1.16.5

~ (*) > tailscaled --version   
1.8.6
  go version: go1.16.5

Unstable is indeed at the latest version, however, stable (21.05) is at 1.8.6. The latest tailscale has not been backported.

Ah, thank you! Didn’t realize the nixpkgs I was looking at was for unstable.

Is it possible to create an overlay that builds 1.14.0 in NixOS 21.05? I’m still new to NixOS, learning overlays is on my todo list, but haven’t gotten to that yet.

This article in the wiki should provide a few pointers
