Major Version Transitions

  • v2.1.0 and v2.1.1: Explicitly save compatible.
  • v2.5.0 and v2.5.1: Explicitly save compatible.

Updating Between Minor Versions

Within a major version line (e.g., v2.2.0 to v2.3.0), saves may or may not be compatible. Always check the patch announcement thread before updating an active game.
