Hello, the new version have been updated for all linux images except arch-based distros, the pacman file has not been updated since August. could you please update them too please?

Hey, a few reasons have been given for this.
It's difficult to package electron forge applications for arch. I'm sure this is not an excuse, but there is an AUR package called cider2-bin atm, or you can use the flatpak/AppImage at the moment. I'm with you, I'm also getting frustrated for this, but I doubt this is gonna do any better.
