The variants `on`, `1`, and `yes ` for enabling and `off`, `0`,
and `no` for disabling are no longer supported.
==== Groovy dependencies
In previous versions of Elasticsearch, the Groovy scripting capabilities
depended on the `org.codehaus.groovy:groovy-all` artifact. In addition
to pulling in the Groovy language, this pulls in a very large set of
functionality, none of which is needed for scripting within
Elasticsearch. Aside from the inherent difficulties in managing such a
large set of dependencies, this also increases the surface area for
security issues. This dependency has been reduced to the core Groovy
language `org.codehaus.groovy:groovy` artifact.
