Hi!

We did a rolling upgrade from version `7.6.1` to `7.12.1` as documented in [Rolling upgrades | Elasticsearch Guide [7.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/rolling-upgrades.html). We have three nodes in our cluster. Before the upgrade each node had roles `dilm`, but afterwards they are all `cdfhilmrstw`:

```nohighlight
curl 'http://localhost:9200/_cat/nodes?v&h=node.role,master,name&s=name'
node.role master name
cdfhilmrstw - es-dev-node0
cdfhilmrstw * es-dev-node1
cdfhilmrstw - es-dev-node2

```

Why did they change? And what are the implications?

Thanks!

From [cat nodes API | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/cat-nodes.html);

> Roles of the node. Returned values include c (cold node), d (data node), f (frozen node), h (hot node), i (ingest node), l (machine learning node), m (master-eligible node), r (remote cluster client node), s (content node), t (transform node), v (voting-only node), w (warm node), and - (coordinating node only).

There's no change as such, it's just further clarification and separation of the existing roles.
