+compatibility (source and binary) with Qt 5.3.0.

+distribution. The documentation is also available online:

+ http://qt-project.org/doc/
+
+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.

+
+ - Use Q_NULLPTR for null pointer purposes with NULL fallback for Qt4.
+ - The WinCE implementation is moved into its own separate module.
+ - Disabled automatic header precompilation for QtSerialPort, since it is
+ more expensive than the benefit.
+
+ - QSerialPortInfo:
+ * Added support for the VID/PID of PCI serial ports from the Sysfs backend.
+ * Fixed mixed up vendor and product identifiers by using of Udev backend.
+
+ - QSerialPort:
+ * Added support of custom baud rate on QNX.
+ * Improved the error handling.
+ * QTimer is now used with zero interval to defer starting of writing on
+ Windows to next event-loop entering. It allow to accumulate a multiple
+ write() calls to futher write of whole buffer instead of chunks.
+ * [QTBUG-36758] Fixed the waitForBytesWritten() behavior on Windows.
+ * [QTBUG-38640] Now a states of the DTR/RTS signals are initialized after
+ opening.
+ * [QTBUG-39369] Do not emit the error() in destructor of QSerialPort; this
+ error signal may then call slots of already (partially) deleted objects.
+ * Fixed the error message for TimeoutError on Windows (which has the
+ WAIT_TIMEOUT error code).
+ * [QTBUG-39314] Fixed regression of waitForReadyRead() method on Windows.
+ * Added handling of the ENOENT error code in uclibc on Linux. Now this error
+ is interpreted as DeviceNotFoundError.
