I will do a more detailed review later, but here's a first glimpse of Ghost 4.0:
The editor itself got a small design update, and looks more clean and streamlined in my opinion.
Ghost 4.0 features a dashboard which includes updates and getting started guides from Ghost. The Dashboard also provides statistics and charts about your publication, including MMR, total members, paid members and email open rates.
I am in the process of migrating my Substack to Ghost, so I will have more updates on that later on.
Casper Theme also got a refresh to match Ghost 4.0. You can download Casper 4.0 from GitHub. I didn't have a chance to dive into it or optimize it yet, but compared to Casper 3.x I find it cleaner and more modern. Great stuff.
Ghost 4.0 brings design improvements across the admin panel. Most notably there's a new Settings page that houses everything about theme configuration and memberships. Also dark mode isn't in Labs anymore, and it activates automatically based in your system settings.
