+Here is what I plan to put in the change log
+
+Changed how Execution objects are created and passed from the cont environment to the execution environment. See chapter 13.9 on worklets in the user manual for details.
+----
+Example of new execution object:
+```cpp
+template <typename Device>
+struct ExecutionObject
+{
+  vtkm::Int32 Number;
+};
+
+struct TestExecutionObject : public vtkm::cont::ExecutionObjectBase
+{
+  vtkm::Int32 Number;
+
+  template <typename Device>
+  VTKM_CONT ExecutionObject<Device> PrepareForExecution(Device) const
+  {
+    ExecutionObject<Device> object;
+    object.Number = this->Number;
+    return object;
+  }
+};
+```
+
+Instead we will now fill out a class and call prepareForExecution() and create the execution object for the execution environment from this function. This way we do not have to template the class that extends `vtkm::cont::ExecutionObjectBase` on the device.
