+ - The creadersync example should not return true when an empty buffer was read.
+ - Improved data receiving in creaderasync example. Received data should be
+   accumulated at each triggering of readyRead() during wait timeout.
+
+ - QSerialPort:
+   * [QTBUG-33938] Fixed crash when closing serial port on Windows. Now the
+     signals/slots are used instead of overriding the QWinEventNotifier::event().
+   * Improved the low-level data writing on Windows. Now a whole writeBuffer
+     is written instead of chunks.
