kde framework 5.21

["C. Mourad Jaber" <ml@nativobject.net>]

Hi,

As the 5.21 version of kf5 is out, I'm asking the question of the debian integration 
process which is very long at this moment.

I have some questions :

What is the maturity of kf5 (5.19) in experimental ?

Is it usable ? if yes why it stay in experimental ?

Regards

Mourad
