+		The Vector team is pleased to announce version 0.40.1!
+
+		This is the first release with packages signed with the new GPG key as part of [Datadog's key
+		rotation](https://docs.datadoghq.com/agent/guide/linux-key-rotation-2024/?tab=debianubuntu).
+		This should be a transparent change for users as the package repository setup script
+		[setup.vector.dev](https://setup.vector.dev) has already been importing the new key;
+		however, if you were manually managing the trusted GPG keys, you will need to update to
+		the newer ones (either [apt](https://keys.datadoghq.com/DATADOG_APT_KEY_C0962C7D.public) or
+		[rpm](https://keys.datadoghq.com/DATADOG_RPM_KEY_B01082D3.public).
