So, I logged into the Ghost admin panel and saw an update notification staring back at me. Remember my first update?
I didn’t read the changelog. I simply decided to update. This time it was simple. All I did was backup my Ghost directory, wget the latest release, unzipped it (overwriting everything) and restarting the Ghost service. It works fine.
Still not as simple as WordPress, but painless for sure. I think theme updates are more painful.
