 # Master (will become release 2.9)
 
+- UGGrid is now thread safe on the grid view.
 - The `Geometry` interface was extended by methods `jacobian(local)` and `jacobianInverse(local)`
   and corresponding typedefs `Jacobian` and `JacobianInverse`. All grid implementations need to
   provide the new interface. For transition, the methods and typedefs are default-implemented
