I've upgraded this site (and https://troop243azle.org) to version 4.0 of the Ghost CMS. Once again, it did not completely trash the site (that's twice in a row!), and my custom theme worked with just one minor warning.
However, after the upgrade I noticed the Ghost folks had a new Theme called "Edition" that highlighted some if it's new features. I noticed it looked very close to the front page of the original 1.0 and below Casper Theme (which my theme was still based on), but with some of the nice updates for blog posts from version 2 and 3.
So I forked the Theme on Github took out the subscriber stuff and made some other visual modifications. I'm still tweaking it but it's a nice refresh for the site (I think). It can be downloaded here:
