How hard is updating to new Launcher

[Losarot]

Hey everybody , im starting my semester of school but was hoping to get updated on the old Minecraft and maybe be around someday.
But it seems lot of changes have gone on since i was here last both in server and in the game itself.

So any advice on updating to the new launcher im really behind on things and could use a hand.
Anything i need to know about the server too, anything new besides Invun being in charge of stuff ,
(who let that happen )

See you soon I hope

If you log in to the old launcher, there's a big button at the top which says that there's a new launcher available with a download link, I think. Click that and it's all pretty self-explanatory.
