Some things have improved, the first to come to mind is that Ruger finally realized that most 10/22 buyers were scrapping the mag release for a better one, so Ruger put on a better one as standard equipment.
Some things have gotten worse, trigger pull is lawyered a bit heavier, some dislike the new finish options.
Some things are just a bit different, plastic trigger group is a good example ... not better or worse, just a change.
Some things are the same, the iron sights on a basic 10/22 are pretty lousy, but there's a rail and you can mount Tech-Sites** or most rimfire optical devices.
They remain modular and amazingly supported by aftermarket parts, if there's something you don't like on a new model, Volquartsen* or another source can fix you up, I think the 10/22 and Marlin model 60 (including variants of both) are tied for most common rifle in America, so there's tons of stuff to bolt on to them.
I just got my third in the cabinet, there's the one I mocked up to be a M1 Carbine trainer, a plain-jane model MrsBFD likes to run with an optic, and I just got one of the new production Mannlicher stock models, I'll be dropping in some VQ parts and adding tech-sights eventually, I suppose.
