http4k v4.13.1.0 Release Notes

    • http4k-* : Upgrade some dependency versions.
    • http4k-core : Rename AsyncHttpClient to AsyncHttpHandler (deprecation).
    • http4k-contract : Fix #664 - Introduce OpenAPIJackson to not serialize nulls by default into OpenAPI specs. If you use your own Jackson instance, you can replicate this behaviour by using .setSerializationInclusion(NON_NULL) on your custom ObjectMapper implementation.
