On the "New Features" in 5.2 page:
There is a heading:
Several Entity Framework Core Enhancements
Entity Framework Core v1.1.x is now supported, Firebird is now a supported database for Entity Framework Core and read-only entities are now supported.
Clicking on the "Read More" link takes you to a discussion of the "Plain SQL" feature in the 5.1 documentation, which I think is unintentional.
