  *Autoscaling*
  
  * Solr now includes a default autoscaling policy.
  This policy can be overridden with your custom rules or by specifying an empty policy to replace the default.
  
  * The ComputePlan action now supports a collection selector to identify collections based on collection properties to determine which collections should be operated on.
  
negative.code: be enabled with a system parameter passed at start up before it can be used.
  For details, please see the section <<package-manager.adoc#package-manager,Package Management>>.
  
  With this feature Solr's Blob Store functionality is now deprecated and will likely be removed in 9.0.
