==== asString() No Longer Allow Nulls
-The `asString()` step will no longer allow `null` input. An
`IllegalArgumentException` will be thrown for consistency with all other
parsing steps (i.e. `asDate()`, `asBool()`, `asNumber()`).

-==== Javascript Set Deserialization
+==== Serialization Changes
+
+*Properties on Element Serialization in Python & Javascript*
+
+Element properties handling has been inconsistent across GLVs.
Previously,`gremlin-python` deserialized empty properties
Review Comment:
It's more of making it consistent with Java deserialization of properties
into lists. Go already deserialize into empty slices, will have to see about
updating the structure, but good point on .NET, a change is needed there. I'd
say it's a separate PR though.

> The {{properties}} property on {{Element}} in javascript has datatypes
> inconsistent with Java and other GLVs where it can be a {{Map}}, {{List}} or
> {{undefined}} depending on serializer or other factors (and we go through
> great lengths to assert all of this in tests for some reason). The type
> should be {{List}}. Use an empty list if {{null}} or {{undefined}}.
