I’m suddenly seeing this message – seemingly every time I install an updated package. It’s been happening since 1.12.0 I think (or maybe just since 1.12.1). The packages I know that I’ve seen it with are linter-perl-check-syntax and github-plus; there may have been a 3rd package as well. Before this, I can only remember seeing restart prompts right after I started using Atom and went on a package installation spree; I don’t think I’ve ever seen it with package updates.
Did something change that necessitates the restarts? I’m not overly concerned about them, but it is changed behavior.
