+- update to version 5.47:
+  This release contains various fixes to GATT, A2DP and BR/EDR vs
+  LE bearer handling. There’s also a notable SDP fix for CVE-2017-
+  1000250 (part of the recently announced BlueBorne vulnerabilities).
+  Feature-wise, there’s now support for adding the appearance and
+  local name to advertising data through the Advertising D-Bus
+  interface. The btmon tool is now also able to better decode most
+  Bluetooth 5.0 HCI commands and events.
+  The Bluetooth Mesh Profile specification was released recently,
+  and this BlueZ release comes with initial support for it in the
+  form of a new meshctl tool. Using this tool it’s possible to
+  provision mesh devices through the GATT Provisioning Bearer
+  (PB-GATT), as well as communicate with them (e.g. configure them)
+  using the GATT Proxy protocol.
