As noted in PR #145 the "integer" type was removed in v5.

In issue #79 from last month, @awwright was still talking about "integer" as a type. Neither @epoberezkin nor I recall any discussion of removing it. @awwright , @Relequestual what was the rationale here?

Requiring the use of {"type": "number", "multipleOf": 1} for a very common use case seems burdensome.
