We will add markup to support Coronavirus information sharing, targeted at local organizations who are already updating their sites with information. The intent is to capture with a bit more structure some of that information, and to establish a model that can be iteratively improved during the crisis response period.
There are also minor changes in other areas of schema.org such as our (already extensively discussed) treatment of online events.
I will publish 7.0 imminently and we can refine things from there, at an accelerated pace.
