If you mean the general way of using it, and stability, yes.

But it is not stale, there have been a few releases in the last years, last one only about a month ago.

One new feature they introduced was 'tabbed windows'.

That's what I meant. There are no breaking changes. My config works the same as back then. I can use new features, but nothing forces me to use them, no "designer" decides I have to work differently after this update.
