The in-game update notice says just that, "Game balance adjustments."

Nintendo support says the following:

Adjustments have also been made to balance the game and make for a more pleasant gaming experience.

What has been changed? I'm noticing some AI changes I think.

    I heard Diddy Kong was nerfed. Perhaps that is one of the balancing changes they've made.

The list is quite long, but you can view the balance (and other) changes here: http://www.ssbwiki.com/List_of_updates/1.0.6_changelog

    I can add a list to this answer so that it isn't a link-only answer, but I think it's best to wait a few more days for the list to stabilize, since it's based on player testing and still being updated.

    I wish Nintendo would have released a full changelog themselves, instead we have to rely on user testing.

  • Diddy Kong nerfs, good god, I'm so happy. ^_^ Commented Apr 21, 2015 at 10:00

Nintendo does not release any changelogs. The only ones that exist are crowdsourced by Smashboards and r/smashbros reddit, and are done by just people noting things and testing on an unpatched system.

I do diffs of the raw data files and upload them to my website here, but I haven't done the new patch yet. http://opensa.dantarion.com/s4/mastercore2/

The community changelog is here: http://smashboards.com/threads/mewtwo-patch-version-1-0-6-thread-updated-sun-10pm-pst.398902/

    Could you post the information from the links into your answer? The links you posed might die, which would make your answer a lot less helpful. Commented Apr 20, 2015 at 20:51
  • @Someguy112161 Normally I would agree, but the first link is a data dump that does not yet have the 1.0.6 changes (so they can't be posted here yet even if they do fit reasonably), and the second link is an ongoing forum topic that is frequently changing as users post their discoveries or suspicions. It will make more sense to post the information once the forum topic calms down and dantarion has the data to verify its claims.

  • @dantarion Are you the same guy who made kenbot?
