+
+  * Move implementation of internal_{type,var,etc} methods back into global namespace.
+    (Tim Wojtulewicz, Corelight)
+
+    This fixes an unknown symbol error if using those methods. They're defined
+    as extern in the global namespace in Var.h, but Var.cc had their
+    implementations defined in the zeek::detail namespace.
