This question already has an answer here:
I recently purchased a new laptop, and I decided to take the plunge and get Ubuntu 18.04, despite it still being in beta. While there have been a few minor quirks here and there, for the most part it's worked fine for me, and I'm pretty happy for it.
When ubuntu 18.04 is officially released on April 26th, will I have to download it onto a bootable thumb drive and update that way, or will my version be equivalent to the full version as long as I continue to regularly install updates?
In summary, What is the correct way to update from a beta version once the full version has been released?
