  +a netty work around for https://github.com/netty/netty/issues/327[a high CPU usage issue] with early JVM versions.
   This bug was http://bugs.java.com/view_bug.do?bug_id=6403933[fixed in Java 7]. Since Elasticsearch 5.0 requires Java 8 the settings is removed. Note that if the workaround needs to be reintroduced you can still set the `org.jboss.netty.epollBugWorkaround` system property to control Netty directly.
   
   ==== Forbid changing of thread pool types
  
positive.code: a fallback realtime setting for the get and mget APIs when realtime
  wasn't specified. Now if the parameter isn't specified we always
  default to true.

  ==== Indexed script settings
  
  Due to the fact that indexed script has been replaced by stored
  scripts the following settings have been replaced to:
  
  * `script.indexed` has been replaced by `script.stored`
  * `script.engine.*.indexed.aggs` has been replaced by `script.engine.*.stored.aggs` (where `*` represents the script language, like `groovy`, `mustache`, `painless` etc.)
  * `script.engine.*.indexed.mapping` has been replaced by `script.engine.*.stored.mapping` (where `*` represents the script language, like `groovy`, `mustache`, `painless` etc.)
  * `script.engine.*.indexed.search` has been replaced by `script.engine.*.stored.search` (where `*` represents the script language, like `groovy`, `mustache`, `painless` etc.)
  * `script.engine.*.indexed.update` has been replaced by `script.engine.*.stored.update` (where `*` represents the script language, like `groovy`, `mustache`, `painless` etc.)
  * `script.engine.*.indexed.plugin` has been replaced by `script.engine.*.stored.plugin` (where `*` represents the script language, like `groovy`, `mustache`, `painless` etc.)
  
  ==== Script mode settings
  
  Previously script mode settings (e.g., "script.inline: true",
  "script.engine.groovy.inline.aggs: false", etc.) accepted a wide range of
  "truthy" or "falsy" values. This is now much stricter and supports only the
  `true` and `false` options.
  
  
  ==== Script sandbox settings removed
  
  Prior to 5.0 a third option could be specified for the `script.inline` and
  `script.stored` settings ("sandbox"). This has been removed, You can now only
  set `script.line: true` or `script.stored: true`.
  
  ==== Search settings
  
  The setting `index.query.bool.max_clause_count` has been removed. In order to
  set the maximum number of boolean clauses `indices.query.bool.max_clause_count`
  should be used instead.
  
  ==== Memory lock settings
  
  
negative.code: exception. Keeping with Elasticsearch's continual movement towards safer out-of-the-box defaults,
  and optimizing for the norm instead of the exception, the default for
  `node.max_local_storage_nodes` is now one.
