I'm not a Ghost(Pro) member, so I need to check Ghost's updates pages and update manually, albeit through Softoculous.
Two main updates that are of interest to me:
1. Browser-based spell check now works
2. Mobile image uploads
3. A cool next/previous function at the bottom of posts.
The first is automatic. The second is something I've been waiting for, for quite some time! The third is manual if you're not using the default theme, Casper. Otherwise you either wait for the developer or you hack it yourself.
I went with the latter option and I've been spending the last couple of hours trying to get it to work. I got the aside in to the post.hbs as well as the CSS from the casper theme.
I've tweaked the background image shader and the H2 colour, but I still can't get it to look like it does on the casper theme! If I can't crack it in the next couple of days, I'm going to remove the styling and hope Marcos at GhostHit implements it.
