Colan Nieslen posted on Twitter something that most people in the local space wouldn't even notice, a redesign to the Google Posts creation tool within Google My Business.
The new user interface gives you three options for posting these Google Posts now, (a) what's new, (b) event and (c) offers.
Here is the new design, that I cannot replicate myself, so it must be a test:
The current interface has some of these options but places them at the bottom. Either make this post an event or choose a button (such as offer, buy, learn more, etc). Here is a screen shot of that interface:
I guess Google is tweaking this interface based on how users are using it.
Forum discussion at Twitter.
Update: Colin also shared the new preview:
