The new development page is up.
Yep. As your quote indicates, that was about 9 months ago. It was a little longer ago than that that I stopped playing DF regularly - in no small part because the new military stuff was (and still is, from what I hear?) so buggy as to make the combat part of the game full of landmines of people not training, training forever, refusing to put down training weapons and using them in combat, etc.
And certainly, most of the big ticket items I mentioned in the OP are on that 9 month old list.
The problem is that they're all still in white. "Future goal." While there's been some stuff added to DF in that time, there's been very little that improves the playability of the core game. You have to expect some level of... odd priorities... in small, indie projects like this one. But going for a year or more pretty much messing about behind the scenes (i.e. world generation which is only accessible in legends mode) and not making improvements to the player-facing stuff (fixing broken systems - military. And god, how long has the economy been broken to the point that it's better to just turn it off? - new features, and improvements) is asking for trouble, I think.
I just look at Minecraft ($30 million + in sales so far) and think "damn it, Dwarf Fortress is better than that game, it deserves at least a fraction of that much," and I've got to say, I think bees are part of the problem. I wish the donation drive had have been for long-requested features, instead of more animals. I would have paid serious money for that!
