-## v1.0
+## v1.0 [unreleased]
 
 ### Release Notes
 
+**Breaking Change**: Aerospike main server node measurements have been renamed
+aerospike_node. Aerospike namespace measurements have been renamed to
+aerospike_namespace. They will also now be tagged with the node_name
+that they correspond to. This has been done to differentiate measurements
+that pertain to node vs. namespace statistics.
+
 **Breaking Change**: users of github_webhooks must change to the new
 `[[inputs.webhooks]]` plugin.

 ### Tags:
 
-All measurements have the following tags:
-  - path
+Measurements don't have any specific tags unless you define them at the telegraf level (defaults). We
+used to have the path listed as a tag, but to keep cardinality in check it's easier to move this
