Hi there,
the Theme has never allowed you to directly edit elements such as featured images or post meta: date etc.
These are all theme elements, there are several options in the Customizer that allow you to display different post meta or the position of the featured image. They can all be found under Customizer > Layout > Blog.

What in particular do you want to change ? Is it the style – let us know if you have an example and i can look at what we can do.
