-libmygpo-qt version 1.0.8 supports also building the library with Qt5. The API is the same as in the Qt4 library. To build the library with Qt5 add "-DBUILD\_WITH\_QT4=OFF" to your CMake command line. Please note that Qt5 support is still experimental. If you find anything to not work with Qt5, please report a bug.
+libmygpo-qt version 1.2.0 supports also building the library with Qt6. The API is the same as in the Qt5 library.

-Just some quick Ideas what could be done better with libmygpo-qt 2.0 ;)

--   Code Reusabillity (e.g. Slots error, parse(QByteArray) & parseData are the same in many classes)
-    -   possible in v1.X? Only Private Classes need to be changed to use a "ParsableResult" as Parent ...
--   Investigate if it is possible to return QString instead of QNetworkReply\* for Data that will not be parsed (OPML, TXT, XML)
--   Merge Functions that return unparsed data in different formats to a function with an enum parameter for the format
--   Memory vs. RunTime in Objects (e.g. DeviceSyncResult): Save Lists & Co only as QVariant (needed for Properties) and parse on demand or save parsed & QVariant (still possible in v1.X)
