The only _language_ change is the removal of the notion of core types [as explained by Robert Griesemer recently.](https://go.dev/blog/coretypes) There’s plenty going on behind the scenes, though, like the [new experimental garbage collector](https://github.com/golang/go/issues/73581) and changes to both `GOMAXPROCS` and the generation of debugging information.

Plus, Go’s excellent profiling story means you’ll be able to chase down any memory or thread leaks.
