What's New, You Ask?

I've released a tiny little macOS menubar utility I use to quickly swap my SSH config files between different environments or use cases. It's called Sshwitch.

Side note: On this website, I am using the super-cool Input font for this site. If you write code and you want to use it for your code editor, grab it here: https://input.djr.com/
