No new launcher here, and the old one worked fine.
I am on a PC is this a console thing?
No - it is no game update, just a new launcher. I played today, then did something else, and after trying to start again the launcher reported, that it needs an update. It downloaded the update, I installed it, started it and had to log in (normally it remembers the login). The only problem was that the verification email did not arrive. I had to wait around 30 minutes, when I tried again, the email arrived in less than a minute, and I could play. The game files did not update, it was only the launcher.
I suspect, that they distributed the launcher and maybe will continue to distribute it in 'waves', because if 1000s of players need a verification email it may not work. Also the new launcher is probably a preparation for the coming update. Good idea to distribute it before the actual update.
If your launcher worked without update, you either have already the last version, or you will receive it soon, I think. I am playing without Steam, btw.
