Beginner path

Do Valheim Old Saves Work With 1.0?

Yes.
Old Valheim saves remain available in 1.0.
New biome generation works properly in areas that have not been explored, so an old world and a freshly generated world may offer different Deep North terrain.

Beginner path

Valheim 1.0 Achievements: Why They May Not Unlock

Valheim achievement tracking starts when you install 1.0, so pre-update boss kills do not automatically unlock achievements.
Check whether the character or world has a permanent cheat flag, or whether marked spawned items are causing a temporary cheated state.
Removing all marked items can clear the temporary state; it does not remove a permanent flag.
