There is no official errata out yet. They will be taking surveys come the new year asking for feedback, and if certain things are considered broken or a problem by a huge percentage of the gaming populace, then they have said they will probably put out an official errata document on it at some point. But I personally wouldn't expect it until the summer of 2015 at the earliest.
There currently *is* a section here on ENWorld that has compiles a list of tweets from the D&D designers that give their personal decisions on certain rules that many people find unclear or not specific enough. But in most cases, they preface what they say with something along the lines of "If I was DMing this, I'd say..." Thereby making the point that the tweet is not "official errata" but merely what they would rule at the table at the time.
And that's how much of what all these "official rulings" are about. Many rules being written generally enough to give you a format for how they work, but not so specific that it takes three pages of documentation to cover every single facet and corner case. And that it's up to every DM to make their own ruling on those facets and corner cases if or when they come up.
If you want to play 5E... then either buy the books or just use the Basic rules from the website. There will places in both where you're going to say "Hmm... this rule's not completely clear to me, how is this really supposed to work?" and then make your own ruling on the matter. But if you want to play 5E... that's one of the cardinal tenets of the game-- "Rulings, not rules" that you either accept as the price for playing, or you don't.
