Super Smash Bros Ultimate will be upgrading to version 4.0.0 this week, but replays recorded before version 3.1.0 won't be compatible with the new update.



#SmashBrosUltimate replays created in versions before 3.1.0 are not compatible with 4.0.0, which releases within 7 days. If you have replays you want to keep, you'll need to convert them by going to Vault -> Replays -> Replay Data -> Convert to Video before updating the software. — Nintendo of Europe (@NintendoEurope) July 29, 2019

Nintendo of Europe announced the news on Twitter, posting "#SmashBrosUltimate replays created in versions before 3.1.0 are not compatible with 4.0.0, which releases within 7 days."If you have replays you want to keep, you'll need to convert them by going to Vault -> Replays -> Replay Data -> Convert to Video before updating the software."Some eagle-eyed fans, including the leaks account Nibel , spotted that the original tweet by Nintendo of Europe read "which releases 31/07", which suggests the new version should be going live in the next two days. The tweet has since been deleted, however.Elsewhere in the Twitter thread, Nintendo of Europe confirmed that a 22-minute Super Smash Bros. Ultimate video presentation will be taking place on July 30 at 6am PT/9am ET/11am BST to reveal more information on the new DLC character, Hero, from the Dragon Quest series. Not much else is known about the patch right now, but when Version 4.0.0 goes live, any significant changes will be outlined in the patch notes on Nintendo's official website.While Evo kicks off this weekend and will see some of the world's best Smash players compete, the stage will be using the previous 3.1.0 patch instead because of an earlier patch lock. This means that even if new character Hero releases in a few days, he won't be playable at the tournament.You can read more about the 22-minute Smash Bros. Ultimate presentation happening this week here , or check out the Nintendo Switch's jazzy new Joy-Cons.
