I would love an one click upgrade solution which doesn't use git in the background. git works flawlessly most of the time but in case something isn't right, it might take unexperienced users a lot of time to fix it (like me, even though I'm a developer, I never really used git).
@v4 I think there´s already a plugin that lets you do that, show the N last posts from a category in the home page. Since you only have one category, i think that meets your requirement. Check the plugins category in this forum, i think you'll find it there.
