Yes. Nintendo shipped Super Smash Bros. Ultimate version 13.0.5 on September 1, 2026, the first update since June 2025. The only listed change is a fix for invalid data sent or received in online battles. This is not a Switch 2 edition or graphics upgrade.
Nintendo says replays from versions 9.0.0 to 13.0.4 may have compatibility issues; older replays are incompatible unless converted to video first (Vault then Replays then Replay Data then Convert to Video).
