Same for us for Go. The releases have never caused any trouble and the performance improvements are nice to have. For us it’s just changing one base containers version.

That being said we still use mostly Python 2 for our Python services.

If those Python services are going to last beyond 2020 and there's much risk of attackers probing for security vulnerabilities, I suggest you plan a transition to Python 3 during the remaining ~2-year support lifespan of Python 2.

It's a lot easier of a transition than it used to be. Any other support replacement language would of course also work to keep you secure, but honestly might be more transition work.

If you're a low-value target running unimportant stuff on an airgapped machine, this might not matter.
