+Qt 5.3 introduces many new features and improvements as well as bugfixes
+over the 5.2.x series. For more details, refer to the online documentation
+included in this distribution. The documentation is also available online:
+
+  http://qt-project.org/doc/qt-5.3
+
+The Qt version 5.3 series is binary compatible with the 5.2.x series.
+Applications compiled for 5.2 will continue to run with 5.3.
+
+Some of the changes listed in this file include issue tracking numbers
+corresponding to tasks in the Qt Bug Tracker:

+
+QtBluetooth
+-----------
+
+ - Documentation:
+   * The documentation for the Bluetooth discovery classes has been
+     improved.
+   * QBluetoothSocket's local name, port and address property documentation
+     improved.
+   * Documentation of all examples improved.
+
+ - General:
+   * Added a new Object-Push example.
+   * QML scanner example was optimized for high DPI displays and
+     error handling was improved. This ensures a better user interface
+     for Android and BlackBerry devices.
+   * Replaced tennis example against new QML based PingPong example.
+   * Test application added. This application enables easier testing
+     and debugging of the various API features.
+
+ - BluetoothDiscoveryModel:
+   * Improved error handling of device discovery process.
+   * Fixed incorrect behavior when changing from device to service discovery
+     and vice versa.
+
+ - QBluetoothDeviceDiscoveryAgent:
+   * Added checks and error enum value to avoid incorrect handling of
+     non-existing local Bluetooth adapter addresses.
+
+ - QBluetoothHostInfo:
+   * Copy operator added.
+
+ - QBluetoothLocalDevice:
+   * Added a new API elements to retrieve connected Bluetooth devices
+     and to receive notifications about connection changes.
+
+ - QBluetoothServiceDiscoveryAgent:
+   * Fixed the fallback backend's initial state and error values.
+   * Duplicated code was removed.
+   * QBluetoothServiceDiscoveryAgent::clear() was improved to avoid
+     unpredictable class behavior.
+
+ - QBluetoothServer:
+   * Checks added to avoid calls to listen() while the server socket is
+     already listening for incoming sockets.
+   * Fixed inconsistent state() of server object after failed service
+     registration attempt during listen() call.
+   * Fixed incorrect parameter type of error() signal. This fixed issues
+     whereby QObject::connect() could not find the signal.
+   * Added custom uuid to serial port service SDP data set. This enables
+     the discovery of such profiles on Android devices.
+
+ - QBluetoothServiceInfo:
+   * Fixed broken implementation of serviceClassUuids().
+
+ - QBluetoothSocket:
+   * Fixed a crash in Bluez part of QBluetoothSocket() which was caused
+     triggered when calling the sequence connect() - abort() - connect().
+   * Fixed missing initialization of the internal socket error state
+     variable. This caused incorrect QBluetoothSocket::error() right after
+     class instantiation.
+   * Synchronized handling of errors across all supported platforms.
+
+ - QBluetoothUuid:
+   * Fixed wrong value of PnpInformation enum value.
+   * Added newly defined ServiceClassUuid's defined  Bluetooth forum.
+
+
+QtNfc
+-----
+
+ - Documentation:
+   * Added missing documentation to QQmlNdefRecord.
+   * General documentation fixes add.
+
+ - General:
+   * Added a new corkboard example displaying the content of NDEF text
+     records.
+   * A new NFC share API was added. The API provides sharing of NDEF
+     messages and arbitrary files via NFC and may potentially use other
+     communication protocols such as wifi or Bluetooth as part of its
+     implementation.

+****************************************************************************
+
+Android
+-------
+
+ - [QTBUG-33792] QtBluetooth has been ported to Android.
+
+BlackBerry 10:
+
+ - [QTBUG-36626] Fixed a memory leak in QBluetoothServer::listen().
+ - Fixed incomplete implementation of QBluetoothServer::close().
+ - Fixed wrong pairingStatus() returned by QBluetoothLocalDevice.
+ - Fixed accidental loss of remote device information in QBluetoothServer.
+ - Added incomplete implementation of QBluetooth::setMaxPendingConnections().
+ - Fixed always failing call to QBluetoothServerInfo::unregisterService().
+ - Fixed missing emission of ConnectedState by QBluetoothSocket.
+ - Fixed implementation of QBluetoothTransferManager::put() when using
+   together with a QFile.
+
+Bluez/Linux
+-------
+
+ - The handling of powered-off local Bluetooth adapters was improved.
+ - Fixed memory leaks in service and device discovery classes.
+ - Removed dead code from SDP discovery implementation.
+ - Fixed crash during service discovery.
+ - Fixed incorrect invocation of QBluetoothDiscoveryAgent where the
+   remote service address was incorrectly assumed to be the local Bt
+   adapter address. This prevented the detection of the remote service.
+ - Removed caching of QBluetoothSocket::localName() and peerName() values. Under
+   certain circumstances those functions returned wrong values.
+ - Fixed missing update of internal QBluetoothSocket::state during SDP discovery.
+ - Removed assertion during service discovery due to unknown SDP attribute.
+ - Prevented calls to QBluetoothSocket::connectToService() while the socket
+   is already in the ServiceLoockupState.
+ - Fixed failing call to QBluetoothServer::listen(QBluetoothAddress) if the passed
+   address was null.
