@ -17,6 +17,7 @@ IMPROVEMENTS:
according to different node attributes [[GH-4512](https://github.com/hashicorp/nomad/issues/4512)]
* core: Added support for spreading allocations across a specific attribute. Operators can specify spread
target percentages across failure domains such as datacenter or rack [[GH-4512](https://github.com/hashicorp/nomad/issues/4512)]
* agent: Support JSON log output [[GH-5173](https://github.com/hashicorp/nomad/issues/5173)]
* client: Added service metadata tag that enables the Consul UI to show a Nomad
icon for services registered by Nomad [[GH-4889](https://github.com/hashicorp/nomad/issues/4889)]
* client: Refactor client to support plugins and improve state handling [[GH-4792](https://github.com/hashicorp/nomad/pull/4792)]
