+pr: 125606
+summary: Rename deprecation index template
+area: Infra/Logging
+type: breaking
+issues:
+ - 125445
+breaking:
+  title: Rename deprecation index template
+  area: Logging
+  details: The deprecation datastream contains log entries for deprecations that
+    occured while Elasticsearch is running. The deprecation log entries had a
+    mismatch in their dataset name. In order to avoid changing the dataset
+    name in the existing datastream, a new datastream now exists.
+  impact: If querying for deprecations previously using the
+    `.logs-deprecation.elasticsearch-default` datastream, you should now use the
+    `.logs-elasticsearch.deprecation-default` datastream.
+  notable: false
