Valheim 1.0 Update Overview — What Changed

1.0 at a glance

Valheim left early access with the 1.0 release on 9 September 2026. This hub collects everything that changed and whether your old world is still worth continuing.

Three things define the release: Deep North, the final biome that closes the progression line begun in the Meadows; crossplay that unifies PC, Xbox, PS5 and Switch 2; and the game’s first full achievement system. Each gets its own section below, with the platform detail and the complete achievement list maintained on dedicated pages in this channel.
