Wow, I totally didn't expect to see this headline. This version has been in the works for years and the updates have been infrequent as of late.
I remember waiting for the very first version of Dwarf Fortress. I think it wasn't even known as Dwarf Fortress back then, just "the dwarf game". Bay 12 Games was virtually unknown, with several quirky games to its name, and a dozen or so fans on the forum. There was a thread where screenshots and videos of the upcoming game were posted. The full scope of the game wasn't revealed back then: the fact that adventure mode even existed was a total surprise, and so was the fact that it's a sequel to Slaves to Armok. The first announcement was posted on Usenet. Good times.
If you're referring to updates on the state of development, this is resoundingly untrue.
Toady makes multiple entries every week, commenting on things happening, bugs found, and havoc discovered. He's done this consistently since I started following DF, around 6 years ago.
Edit: I should also point out that the brothers are also active on the bay12 forums, conducting monthly Q&A sessions about DF's future, as well as posting monthly donation numbers. There is a DF podcast on which they appear frequently to boot. I mention all of this only to stress that despite DF's odd, irregular development cycle, the Adams brothers are among the most communicative and forthright of dev teams out there.
Edit edit: The above takes into consideration that the devs' communications, updates, changelogs, etc., are just as unorthodox, non-standard and charming as DF itself, and often make for as much entertainment.
