Hello Bruce,
1) First you should go in Website -> Site -> Blog Posts 
2) Try to create New Blog -> Select Blog and Title in popup - It will create new record line in Blog Posts view
3) Now click on new created record and you will redirect to Blog website page with editable options
4) You will find "Blog Post" second last option on right corner - click on that - It will redirect you to this blog's form view - there you can change "Publishing Date" 
5) Now back to the Blog website page with editable options there you will find "Edit" as last option on right corner - Here you can add blog structure blocks and customise same as Web Page

Hope it will be helpful to you.

Thanks & Regards,

Hi Bruce

The settings for blog posts is still available but the way to get there changed a little bit.

1. Go to website -> blog post
2. In the above right corner you will find 'edit blogpost' (you should be logged in)
3. There you can edit

Hope this helps

Greetings
