LocalBusiness has an (optional) recommended property of priceRange, which is a text field that allows you to specify the relative price range for the business (e.g. $100-$250). Google added a clarification that this field must be shorter than 100 characters, otherwise the price range will not be displayed.
Google removed the required property of @id for LocalBusiness, which was designed as a unique node identifier for the specific local business branch.
In their release notes, they claim that 'the url property alone is a sufficient identifier to understand the local business,' which is curious as this remains a recommended property for LocalBusiness.
