When I change jobs, I check which version of my editor the dev environments have installed. If it's too old, I build a local copy of the latest version of my editor. No worries asking IT or Ops to update a package for me.

When it comes to production servers, I'm more likely to build my editor in my home directory than use my sudo privileges to install my editor in the system.

So developers can be building newest versions of code on old systems. I do.
