title: How do I update Wagtail to the latest release?
body: <p>I'm new to Wagtail and I got as far as being able to create an account and now I have access to <a href="http://127.0.0.1:8000/" rel="nofollow noreferrer">http://127.0.0.1:8000/</a>. That said the banner informed me that I have the 1.3 version and I need to upgrade to 1.10. I looked at all the release notes but there were no instructions. How do I go about this? Thank you!</p>
