Yes and no. While Playground Games officially ended new feature development for FH4 in mid-2022, the game still receives occasional critical security or compatibility updates. For example, version 1.478.564.0 was followed by 1.478.564.2 (only for Steam) fixing cloud save conflicts. However, for most players on Microsoft Store or Xbox, 1.478.564.0 is indeed the final stable release.
