@Mark_Harwood or anyone in elastic, has anything changed with ES v7.x?

I observed that the note / warning about update API and external version incompatibility has disappeared from the documentation in version 7.

[https://www.elastic.co/guide/en/elasticsearch/reference/6.6/docs-update.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.6/docs-update.html)  
has the warning.

[https://www.elastic.co/guide/en/elasticsearch/reference/7.4/docs-update.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/docs-update.html) does not have any such warning.

I extended this concept to deal with cases where you have objects within an ES document as the **putAll** only seems to work when you have fields in an ES document and not when you have objects within an ES document that contain fields (properties) themselves.

```auto
POST /transaction_index/_update/33384637-3137-3132-5543-31304c4c3151
{
   "script": {
      "source": "if (ctx._source.Metadata == null || params.Metadata.Version >= ctx._source.Metadata.Version) { for (k in params.keySet()){ if (ctx._source[k] != null) { ctx._source[k].putAll(params.get(k)) } else { ctx._source.put(k, params.get(k)) } } } else { ctx.op = 'none' }",
      "params": {
         "Transaction": {
            "TransactionId": "33384637-3137-3132-5543-31304c4c3151",
            "TransactionKey": "Key1"
         },
         "Message": {
            "MessageId": "505a5953-374a-385a-4a48-52353549445a",
            "Context": "This is a test context"
         },
         "MessageDefinition": {
            "MessageDefinitionId": "a1c05e06-fa6b-40ce-992f-d083ff6c0243",
            "Code": 1010101010
         },
         "Metadata": {
            "Version": 1,
            "CreateTime": "2020-09-04T14:27:51.1986439+01:00",
            "IsLatest": true,
            "IsDummy": false,
            "VersionString": "20200903111111"
         }
    }
 },
 "scripted_upsert": true,
 "upsert": {}
}
