++ Qt 5.8 introduces many new features and improvements as well as bugfixes
++ over the 5.7.x series. For more details, refer to the online documentation
++ included in this distribution. The documentation is also available online:

++
++ QtSerialBus was a technology preview in 5.6 and 5.7. With 5.8, the
++ module leaves technology preview status and the API is fixed.
++ The most important changes done in 5.8 are listed below.
++ QtSerialBus is now binary compatible with following versions (5.9 etc.)

++ QtSerialBus
++ -----------
++
++ - QCanBus
++ * [QTBUG-53642] Changed the signature of createDevice() to use only
++ QString parameters. Furthermore, plugins() now returns a QStringList.
++ * [QTBUG-53642] Changed createDevice() to return an optional textual
++ error description.
++
++ - QCanBusDevice
++ * [QTBUG-52495] Added waitForFramesWritten() and waitForFramesReceived()
++ to QCanBusDevice.
++
++ - QCanBusFrame:
++ * [QTBUG-53171] Added toString() to QCanBusFrame.
++ * [QTBUG-49675][QTBUG-56720] Added CAN FD flag to distinguish CAN FD
++ frames from CAN 2.0 frames. In addition hasFlexibleDataRateFormat()
++ and setFlexibleDataRateFormat() function were added. It permits easier
++ identification of CAN FD frames.
++ * Changed the signature of two constructors.
++ * [QTBUG-51845] Cleaned up the usage of inline and nothrow throughout the class.
++ * Improved validity checking for frame ids larger than 2^29.
++
++ - QCanBusFrame::TimeStamp:
++ * Added TimeStamp::fromMicroSeconds() time stamps with normalized
++ microseconds and added the overflow to seconds.
++ * Removed the setSeconds() and setMicroSeconds() functions to avoid
++ confusion about unnormalized time stamps.
++
++ - Added basic support for Vector CAN devices.
++ - Improved the implementation of the PeakCAN and TinyCAN plugins.
++ - Improved and fixed the CAN examples. In particular the examples were adjusted to
++ the various API changes.
++ - Improved the module and class documentation substantially.
++ - Unified the interface names of the different plugins to follow a common rule:
++ The prefixes were unified, the numbering always starts with zero now.
++ - [QTBUG-55747] Fixed C+11 related code sections which failed to compile on OSX 10.11.6.
++ - Ported canbusutil tool to use QCommandLineParser and multiple other changes to
++ improve the tools internal implementation such as a more streamlined printing to stdout.
++ - [QTBUG-56331] Fixed module build on Android. The canbusutil tool was removed from
++ Android builds.
++ - [QTBUG-56886] Fixed handling of frameReceived() signals throughout all CAN examples.
++ - Converted the module to use the Qt Lite based configure changes in Qt.
++ - [QTBUG-54834] Fixed handling of packets with payloads longer than 127
++ bytes by QModbusResponse.
++ - Added missing QDataStream operator<< for QModbus{Request,Response}.
