    .. versionchanged:: 3.6
       Added support for :pep:`526` variable annotation syntax.
 
+   .. versionchanged:: 3.6.1
+      Added support for default values.
+
+      Usage::
+
+         class Employee(NamedTuple):
+             name: str
+             id: int = 3
+
+         employee = Employee('Guido')
+         assert employee.id == 3
+
+      Fields with a default value must come after any fields without a default. The
+      ``_field_defaults`` attribute stores a mapping from field names to their
+      default values.
