Ok #NixOS peeps. I'm currently running NixOS and subscribed to the nixos-22.11 channel. I installed Vivaldi but I'm not on the latest release.
If search Nixpkgs, I see that the latest release on stable is 5.4.2753.47. However, I can see the pull request and merge to update the package to 6.0.2979.15 on the master branch in #Github. Shouldn't I be getting that version when I update my config?
