Breaking changes in 6.0edit
This section discusses the changes that you need to be aware of when migrating your application to Kibana 6.0.
Removed option to use unsupported scripting languagesedit
Details: Kibana 5.x allowed users to create scripted fields using any scripting language enabled in Elasticsearch. Kibana 6.0 will only support Painless and Lucene expression based scripts.
Impact: You will need to migrate your groovy, python, javascript, etc. scripted fields to Painless or Lucene expressions.
