2 to 3 broke lots of code. Print became a function. Imports moved around. And there were subtle changes in the semantics of some things. Famously, strings changed, and that definitely affected a lot of packages. Quite a bit of that could be fixed by automated tooling, but not all of it, and the testing burden was huge, which meant a lot of smaller packages did not convert very quickly and there were ripple effects. |
