I know, there is a thread for this. I couldn't find it, ok.
OK, SDC shows me Object Dock Plus 2 as an available update.
I have both plus 2 and plus 1.9 installed.
I would like to point out that if I install this "update" I lose 1.9. We used to be able to have both installed, and I do. I had to install 1.9 from the store. SDC lists them both as Object Dock Plus 2.
