And the verdict…. Nothing special.
The upgrade process was extremely simple. Just went through and updated all my plug-ins and theme to be 2.8 compatible and followed the three step upgrade process, and voila.
The admin interface has received a small polishing, with a new theme browser and theme installation method. I like the new editor for use with theme php & css files. The syntax highlighting and automatic documentation feature seems to be the best improvements for me.
So to sum up the installation went very smoothly, but unless you are into customising your themes or changing theme’s often then I don’t see any compelling reason to race out and upgrade.
