+  - |
+    On slower nodes, the initial grafana startup could experience a
+    timeout failure when the migrations for setting up the database
+    took longer than expected. This has been fixed by increasing the
+    default timeout. The timeout settings can be changed via new
+    parameters ``grafana_start_first_node_delay`` and
+    ``grafana_start_first_node_retries`` for the ``grafana`` role.
