I have a BRAND NEW install of 5.3.0 on Windows, an older version(2.3.2) on Ubuntu 16.04  
When I tried to PUT `{"settings": {"mapper": {"dynamic": "strict"}}}` at localhost:9200/test I get this:

```json
{
	"error": {
		"root_cause": [{
			"type": "illegal_argument_exception",
			"reason": "Failed to parse value [strict] cannot be parsed to boolean [true/1/on/yes OR false/0/off/no]"
		}],
		"type": "illegal_argument_exception",
		"reason": "Failed to parse value [strict] cannot be parsed to boolean [true/1/on/yes OR false/0/off/no]"
	},
	"status": 400
}

```

But it works on 2.3.2

Any ideas on why this doesn't work anymore?

What does the entire request look like?

`curl -XPUT 'http://localhost:9200/test' -d'{"settings": {"mapper": {"dynamic": "strict"}}}'`

I'm almost certain it's a version thing, as I mentioned against 5.3 it fails, against 2.3.2 works

I think mapper is deprecated in v5
