Question: the state of LaTeX3

Hello all!

There is some discussion on Hacker News right now regarding Typst, and some commenters lamented the lack of progress in LaTeX; that made me wonder, what is the state of the (long, long) upcoming LaTeX3? The LaTeX project page has very little information on the specifics and I would like to hear about any progress behind the scenes, especially if we have any insiders lurking in here.

Thanks for your time!
