+QtSerialPort 5.3 introduces a few 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/
+
+The QtSerialPort 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:

+****************************************************************************
+*                          Library                                         *
+****************************************************************************
+
+ - Build for WinRT is disabled, since the MSDN Windows Store apps will not have
+   any serial port replacement.
+ - Improved the documentation.
+ - Added error handling to some missing functions.
+ - Removed some unused code related to the SystemIn/OutputQueue size
+   methods.
+ - Now the TxD/RxD signals are obsolete, since there is no reliable low-level
+   API of obtaining the status of these signals.
+ - Now the signal bytesWritten() is emitted only after completion of a write
+   operation (when a payload of data was transferred from the driver's queue and
+   the driver's queue became empty).
+ - [QTBUG-36865] Remove the continuous warning about the unknown flow control.
+ - [QTBUG-35781] Use private linkage where appropriate.
+ - Swap the open and configure error reporting in the terminal example.
+ - Obsolete the "settings restore on close" API.
+ - [QTBUG-37989] Keep qmake's "-framework" option on OSX to fix building.
+ - Fixed display of the serial number in the terminal example.
+ - Mark the settingsRestoredOnClose property deprecated since 5.3 instead
+   of 5.2.
+ - Ensure both input and output baud rates are set.
+
+ - QSerialPortInfo:
+   * [QTBUG-32774] Added the enumerating of virtual serial ports that are created
+     from the "AGG Software" utility on Windows.
+   * [QTBUG-36526] Added an additional enumeration through the SERIALCOMM
+     registry for serial ports which are not present in Windows Device Manager.
+   * [QTBUG-36870] Used Q_GLOBAL_STATIC for the udev symbol loading QLibrary
+     instance.
+   * [QTBUG-31981] Added API for querying the serial number of USB serial ports.
+   * [QTBUG-36296] Fixed info update for FTDI devices on Android by using Sysfs.
+   * [QTBUG-37578] Used QScopedPointer (RAII) to avoid memory leaks with udev.
+
+ - QSerialPort:
+   * Added handling of the ERROR_INVALID_NAME error code on Windows; now this
+     error is interpreted as DeviceNotFoundError.
+   * Optimized writing sequence algorithm on Windows; now there are no excess
+     calls of WriteFile when the writeBuffer is empty.
+   * [QTBUG-36490] Fixed changing the state of the DTR signal when modifying
+     DCB properties; now the DTR signal stays in the same state.
+   * [QTBUG-33987] Fixed the waitForReadyRead() behavior on Windows.
+   * cfmakeraw is no longer used on SunO since it doesn't exist on Solaris and
+     Illumos.
+   * qt_safe_open() is now used instead of open() on Unix since open() is not
+     thread-safe, that can lead to leaking of file descriptors.
+   * [QTBUG-36824] Protected against EINTR in Unix non-atomic I/O calls with use
+     of qt_safe_xxx functions.
+   * [QTBUG-33774] Now there is the possibility to set up the port settings
+     before opening.
+   * Improved the reading and writing algorithm on Windows.
+   * Define CRTSCTS on QNX. Tested on SVTronics UEVM5432 Omap5 board with
+     QNX 6.6.
+   * [QTBUG-38339] Fixed the flush() regression on Unix.
+   * [QTBUG-38961] Fixed regression on Linux when trying to set a custom baud
+     rate.
