Well, it's only been two weeks since the patch notes were updated - that's not all that uncommon.
Maybe Alex need lots of time to balance things now. And he did go with "chains", but he abandon that idea. So, you know, lots of new stuff some gets implemented some gets replaced etc. you need time to balance all that out.
There's definitely some of that. I'm also currently experimenting with something else - not a new feature, exactly, but something I've wanted to do for a while. Call it a bonus for the next update, if it all works out like I hope
Experimentation doesn't lend itself well to patch-notes-style updates, though.
