Release of BlueZ 5.42
The major API change with this release is that the GATT D-Bus API is no longer marked as experimental.This should hopefully encourage the creation of more applications using it. Feature-wise, btmon received support for decoding full mgmt message traces – a feature that is available in the bluetooth-next kernel tree, i.e. on its way to the 4.9 kernel release. In addition to these changes, this release contains also fixes in areas such as PBAP, transport selection (BR/EDR vs LE), ATT and A2DP.
