Steam Native deprecation notice
You will see steam-native-runtime is now a Foreign/AUR package when updating, as it has been moved to the AUR and is without a maintainer. It should be removed, along with its dependencies. Notice the optional dependencies when removing! In case you were relying on an AUR or self-built package with incorrect dependencies which were incidentally fulfilled by Steam Native, it will be helpful to know which packages you may need to reinstall. This mainly applies to relatively old & obscure audio applications.
sudo pacman -Rs steam-native-runtime
The Steam Troubleshooting wiki has been updated accordingly to indicate that you can manually change the runtime, though it shouldn’t really be needed going forward.
