.Third party plugins can no longer intercept REST requests (`RestHandlerWrapper`)
[%collapsible]
====
*Details* +
In previous versions of {es}, third-party plugins could implement the
`getRestHandlerWrapper` method to intercept all REST requests to the node. A
common use of this feature was to implement custom security plugins to replace
the built-in {security-features}. This extension point is no longer available
to third-party plugins.


*Impact* +
Some third-party plugins that were designed to work with earlier versions of
{es} might not be compatible with {es} version 8.0 or later.

If you depend on any plugins that are not produced and supported by Elastic,
check with the plugin author and ensure that the plugin is available for your
target version of {es} before upgrading.
