Cadence of Hyrule burst onto the scene in June and has been kind of low key beloved since then. This latest patch falls in line with the status quo of post-launch support as it doesn't have a ton of Earth-shattering additions, but it gets the job done.
The biggest change is probably the introduction of achievements, which as you probably know, aren't supported by default on the Switch. Developer Brace Yourself Games also managed to sneak in leaderboards for co-op: and if you use co-op at all you'll be forced to use that list. Another interesting tidbit is "Beat Rumble," which is a new options menu toggle that turns your remotes into little beat keepers.
The other changes are mostly small and housekeeping related: things like bug fixes, the chance to see the credits (and thus easily read all the song titles) on command, and other quality of life fixes like better ice and wind character control, as well as color-blind specifications.
That's pretty much all you really need beyond more characters! This game will always be as evergreen as Link's tunic.
