They lazily patched a browser exploit, doing the bare minimum to do so. It was not the point of the 5.5.2 update. They did nothing to stop CFW-usage nor the usage of secondary exploits, for example.So 5.5.1 exploits weren't fixed on 5.5.2?
A specific message regarding the closure of MiiVerse was indeed added in 5.5.2, and that was the primary purpose of the update. Dataming that message from the tiny, otherwise meaningless, update was how we found out in the first place MiiVerse was going to close soon. You're going to have to be specific about which message you received and where. Some messages are online messages.I'm on 5.5.1 and the error messages about Miiverse closing display for me so 5.5.2 didn't do that
