+  * Fix possessive "it's" in contexts docs. (Evan Typanski, Corelight)
+
+  * GH-1966: Reject anonymous units in variables and fields. (Evan Typanski, Corelight)
+
+  * Avoid creating external types unnecessarily during AST construction. (Robin Sommer, Corelight)
+
+    We could end up creating external types for freshly created AST nodes
+    just because we wanted them to have a certain constness/sideness. This
+    could then lead to the original types not being validated because they
+    weren't inserted into the AST anywhere.
+
+    This also extends the AST dump output for qualified types to indicate
+    whether it's an internal or external type.
