It looks like Google is continuing to implement new structured data types. Most recently there have been official annoucements for the Q&A data type and the Livestream data type. Who doesn't like rich results? I know I do! Along with these new data types I believe we are going to see further implementation of sub types accross the board. This also includes more robust support for existing data types. Recently I saw a breadcrumb data type that was displaying images along with the normal links.
In my recent search results on Google Search I noticed that there are some new rich results showing up. Specifically, question and answer results are popping up in the regular SERP data. Thought I would look around for some official information on the topic.
