OK, sparrow 2.3.0 is out! And you can get the Nix package from my Nix flake https://github.com/emmanuelrosa/btc-clients-nix

Did I beat all of the other third-party packages?

The update will make it to Nixpkgs at some point, but it's worth noting that this Sparrow update did not work with the recent Nix package update to Zulu 24. So, I removed the Nixpkgs JDK and went with the bundled JDK, which is something I recently mentioned I may have to do, which is Temurin 22.

One nice benefit of this change is that the package is simpler; Less Nix code.
