[Interest] Is Digia's documentation for QML/Qt Quick lerning obsolete?

[Артур Истомин]

Is this documentation obsolete for latest Qt version?

http://ftp.fau.de/qtproject/learning/developerguides/qtquickdesktop/QtQuickApplicationGuide4Desktop.pdf

Introduction to Application Development with Qt Quick. Release 1.0, 2013
Qt Quick Application Developer Guide for Desktop. Release 1.0, 2013

I like the documentation in this format, long multipages book/pdf, but I'm afraid they are too old for latest Qt version.
Am I wrong?

Thanks you!
