Revision control
++ QtSerialPort 5.2 introduces a few new features and improvements as well as
++ bugfixes over the 5.1.x series. For more details, refer to the online
++ documentation included in this distribution. The documentation is also available
++ online:
++
++
++ The QtSerialPort version 5.2 series is binary compatible with the 5.1.x series.
++ Applications compiled for 5.1 will continue to run with 5.2.

++ Some of the changes listed in this file include issue tracking numbers

++
++ - [QTBUG-31966] Support has been added for non-standard Qt header installation
++ folder (e.g. on Red Hat).
++ - [QTBUG-33125] The generation of the forwarding headers now works with Qt 4 and
++ Necessitas.
++ - [QTBUG-33117] [QTBUG-33139] Fixed the compilation for Android with Qt 5. The
++ command line enumerator seems to work.
++ - Added support for non-standard BSD4 baud rates.
++ - [QTBUG-32173] Rewrote the documentation to more proper English than before,
++ and also improved the accuracy of the content.
++ - [QTBUG-33774] Document that the serial port parameters cannot be set before
++ opening.
++ - No more unnecessary syscalls (parameter settings, pinout signal query, etc) in the
++ backend when the port is closed. This also means no unnecessary errors are set.
++ - Removed the QtGui linkage for the command line enumerator example, so it now
++ links against QtCore and QtSerialPort only.
++ - More warnings when doing operations that require the serial port to be open,
++ but it is closed.
++ - The deprecated QtAlgorithm usage is removed.
++ - Some outputs in the examples are fixed to be more proper English; this
++ includes mostly typos, but also some comprehensive changes.
++ - New command line sync reader example available with screen shot and
++ documentation.
++ - New command line async reader example available with screen shot and
++ documentation.
++ - New command line sync writer example available with screen shot and
++ documentation.
++ - New command line async writer example available with screen shot and
++ documentation.
++ - The buildsystem now respects the configure run for Qt 5, i.e. pkg-config is
++ not used for finding udev again.
++ - [QTBUG-34429] Mark the data error policy obsolete. End users should stop using
++ this feature now. It may be removed later in Qt 6.X, and there is a warning now
++ if it is used.
++ - [QTBUG-34474] Replace the internal QTtyLocker with QLockFile from QtCore and a
++ small convenience on top of it to comply with the locking directories lockdev
++ also uses.
++ - The lock file usage has been extended to support Android as there is no direct
++ access to the usual Unix lock file system paths. The lock file is now placed
++ into /data/local/tmp.
++ - [QTBUG-35184] Mark the isValid() method in QSerialPortInfo deprecated because
++ it has no common use case.
++ - [QTBUG-35215] Mark the QSerialPort::Unknown* enumeration values in QSerialPort
++ deprecated because they have no use case.
++
++ - QSerialPortInfo:
++ * [QTBUG-32684] VID/PID for USB Huawei 3G Modem is returned properly now.
++ * [QTBUG-32018] The port name and product identifiers now work for more devices
++ and scenarios on Windows.
++ * Linux: sysfs support was added for serial port information as a fallback for
++ udev.
++ * [QTBUG-34329] Support added for loading udev at runtime rather than linking at
++ compilation time.
++ * [QTBUG-32563] Motorola IMX support was added when udev and sysfs are not
++ present.
++ * Support has been added for the hard-coded device enumeration backend to get
++ information. Android uarts such as /dev/ttyHS* (High speed UART) and
++ /dev/ttyHSL* (Low speed UART) are supported by that backend.
++ * Support has been added for the hard-coded device enumeration backend to get
++ information. /dev/ttyO* (native OMAP UART) is supported by that backend.
++ * [QTBUG-35064] PCI support has been added to the sysfs backend on Linux to
++ support the enumeration of such devices.
++
++ - QSerialPort:
++ * [QTBUG-32016] No "No such file or directory" error set after waitForReadyRead
++ anymore.
++ * [QTBUG-32017] Windows: Fixed the waitAnyEvent() method for the WAIT_FAILED
++ handling.
++ * [QTBUG-31964] The serial port enums are now properly tagged as Q_FLAGS.
++ * Added native serial port handle; it is now possible to do any custom operation
++ if not supported by QtSerialPort.
++ * [QTBUG-32680] Added API for handling the timeout errors when waiting for read
++ or write.
++ * Added a new error enumeration value called "NotOpenError". This can be used
++ for operations where the serial port is not open. This is also used internally
++ now.
