The most significant change is that examples are now available in RDFa and JSON-LD in addition to the microdata examples previously provided. This addition of these examples fulfills one of the longest-standing requests from webmasters and search marketers, and the JSON-LD examples are particularly welcome as Google has recently been looking upon JSON-LD with greater favor.
The other major change to the site is that under each type a list of the properties for which that type is an valid value appears. This will be a particularly useful feature for webmasters not acquainted with the full vocabulary, and who as a result might not be aware of relevant properties for a type they're employing.
Various bugs are being identified and fixed these changes roll out, but feedback has been overwhelmingly positive for this major schema.org site upgrade.
A final note that at time of writing the JSON-LD examples for the schema.org/Action hierarchy that were previously present have disappeared in this new version of the site (there are now no examples here of any type). I've made an inquiry and will update this post when and if I hear more about the status of schema.org/Action examples.
The update being of the short and sweet variety. Heard back from Dan Brickley about the missing schema.org/Action examples.
They'll be back! Thanks for caring 😉
Also from Dan Brickley, a version number and some additions to the vocabulary.
This is schema.org v1.1. Version 1.1 includes substantial new
vocabulary for describing Reservations(*), a handy Question/Answer
vocabulary much discussed here recently, and a utility type for
EmailMessage. For more details, entry points:
