 <p>The <code class="language-text">ExecutionContext</code> property has been added to the <code class="language-text">IResolveFieldContext</code> interface to allow access to the
 underlying execution context. This is useful for accessing the parsed arguments and directives from the operation
 via <code class="language-text">IExecutionContext.GetArguments</code> and <code class="language-text">GetDirectives</code>.</p>

+<p>When defining an input object or output field argument in a type-first schema, you may now use the <code class="language-text">[DefaultAstValue]</code>
+attribute to specify a default value for the argument. This is useful when the argument is a complex type that cannot
+be represented as a constant via <code class="language-text">[DefaultValue]</code> or in the method signature.</p>
