*facepalm* *sigh*
I apologize for assuming you could actually use the search function after suggesting you do that. It comes so naturally for so many of us what to search for when we know what we want to know. In your case, you wanted to know these things:
1. why the game took so long? will every update take that long and have only as much content?
2. what's new in this update?
So a simple search with the key word "update" should return you with plenty of information simply by glancing at the result. Then a search with the keyword "update" specifying posts by HopesGaming, which is the username of the dev should narrow it down even more to important posts about updates. Or a search specifying posts by HopesGaming without any keyword will give you a general idea about what's been going on since he's very active and friendly toward the fanbase. I just did just those simple searches, and all the important and core information, and pretty much everything you asked for are in the results.
As for your question about what's in this update. I did see it. I chose not to answer because, as stated above, the answers are pretty clear in the search results, as well as the fact that your question is so vague that a short answer will unlikely satisfy you while a long one will take forever to write, not to mention spoil everything. The changelog is probably the best answer anyone can give, and you've already made it clear you're dissatisfied with that.
P.S.: Funny you should say I should get off my high horse, because my attitude is usually a mirror reflection of the attitude gave off by the post I'm replying to. So I seem extremely friendly to some, while to some others...
