This incorporates a large number of patches (each improving the stability and general robustness of the code base). During the process the number of potential asserts was reduced as well. - Deprecated QBluetoothDeviceInfo::DataCompleteness related APIs. - Replaced QBluetoothDeviceInfo::LanAccessDevice with QBluetoothDeviceInfo::NetworkDevice. LanAccessDevice was deprecated. - Implemented support for QBluetoothDeviceDiscoveryAgent::deviceUpdated() on Apple and WinRT platforms. - [QTBUG-71943] Implemented RSSI and manufacturer data discovery on WinRT. - [QTBUG-74394] Fixed broken QLowEnergyController::disconnectFromDevice() on WinRT. - Added a compile fix for g++ 8. - [QTBUG-73717] Fixed warnings in QDeclarativeBluetoothDiscoveryModel. QtNfc ----- - QNearFieldManager: * adapterStateChanged() now has a fully qualified parameter QNearFieldManager::AdapterState. This can cause a problem if the connection/method invocation was done with just AdapterState as the parameter type, in which case these need to be changed to use QNearFieldManager::AdapaterState instead.
