 ### Implicit required plugin
 
-Starting from Version `1.8` many plugins will move out from Packer core. This is
-part of a set of breaking changes made to decouple Packer releases from a Plugin
-release. To make the transition easier we will tag components of these plugins
-as "moved out". If one of the components of a moved out plugin is used in a
-config file, then it is implied that this plugin is required. Packer init will
-install that plugin then display a warning and a suggestion. We recommend on
-using a `required_plugin` block and setting a version to avoid surprises in the
-future.
