| 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. |

| |
| - 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. |
