+      body: |
+        The balena logging backend now uses async functions to setup the
+        connection and write messages to the request stream. This adds some
+        backpressure on `log` calls by by the log monitor module, to prevent a
+        very agressive container causing the supervisor to waste CPU cycles just
+        dropping messages.

+      hash: f3fcb0db7a8478dfe9ffde342b683510ba49502f
+      body: |
+        This make the LogBackend `log` method into an async method in
+        preparation for upcoming changes that will use backpressure from the
+        connection to delay logging coming from containers.
+
+        This also removes unnecessary imageId from the LogMessage type

+      hash: dbacca977a1f42ad4e3381112d3523cf7624d283
+      body: |
+        This removes the dependence of the supervisor on the containerLogs
+        database for remembering the last sent timestamp. This commit instead
+        uses the supervisor startup time as the initial time for log retrieval.
+        This might result in some logs missing for services that may start
+        before the supervisor after a boot, or if the supervisor restarts.
+        However this seems like an acceptable trade-off as the current
+        implementation seems to make things worst in resource contrained
+        environments.
+
+        We'll move storing the last sent timestamp to a better storage medium in
+        a future commit.
