In the past, `fields` could be provided either as a parameter, or as part of the request
body. Specifying `fields` in the request body as opposed to a parameter was deprecated
in 6.4.0, and is now unsupported in 7.0.0.
==== `copy_settings` is deprecated on shrink and split APIs
Versions of Elasticsearch prior to 6.4.0 did not copy index settings on shrink
and split operations. Starting with Elasticsearch 7.0.0, the default behavior
will be for such settings to be copied on such operations. To enable users in
6.4.0 to transition in 6.4.0 to the default behavior in 7.0.0, the
`copy_settings` parameter was added on the REST layer. As this behavior will be
the only behavior in 8.0.0, this parameter is deprecated in 7.0.0 for removal in
8.0.0.
