+- update to version 5.48:
+  This release brings many fixes and feature enhancements.
+  Some notable enhancements include support for devices with the
+  BLE battery service, as well as improved Mesh support in the
+  meshctl tool. Several previously experimental D-Bus APIs have now
+  been marked as stable, notably the Advertising Manager API as
+  well as the AquireWrite & AquireNotify GATT APIs.
+  As far as fixes go, these can be found in many areas of the stack,
+  including A2DP, AVCTP, device discovery, Mesh, and GATT.
