I've really enjoyed Golang for this reason. The powers that be take a cautious approach before adding major new stuff, even when the community complains loudly about lack of important features (e.g. generics for many years until recently). Go code I've written years ago is easy to adapt to new versions and ways of doing things, even when I have to switch gears to others languages for months/years at a time. Go is predictable.
