Does this mean you intend to update your existing examples in place? It might be nice if you forked them with v4 instead to create a defacto upgrade guide.

I know many tutorials reference your examples and it might create more confusion if they are updated in place.

I suppose it depends on how much you want to keep supporting v3, but I'd argue its worth keeping the old knowledge base intact for a while.

Yep, I’m going to update my examples in-place. Consider it my heavy-handed encouragement to upgrade to 4.0. (For one thing, there are lot of 3.x bugs fixed in 4.0, and I have limited resources to provide free support to old versions.) My examples are backed by git repos, so you’ll still be able to find the 3.x versions if you need them.

fair enough!
