Overview
- Nintendo released Version 13.0.5 as a narrowly focused update that corrects behavior caused by invalid data sent or received during online battles.
- The patch is maintenance-only and makes no gameplay or balance changes to Super Smash Bros. Ultimate.
- Nintendo warns that replays from versions 9.0.0 to 13.0.4 may become incompatible and that replays from 8.1.0 and earlier will not work.
- Players who want to preserve important replays should convert them to video via Vault → Replays → Replay Data → Convert to Video before applying the update.
- The release continues infrequent post‑DLC upkeep since 2021 and has prompted unconfirmed discussion about a possible Switch 2 upgrade or a new Smash title.
