RealVNC Viewer 6.22.515 still does not save session passwords (windows)

You said in another post: "We have released VNC Viewer 6.22.315 to correct this bug"

Unfortunatly in Version 6.22.515 is still this bug.

At 3. july the user minkashani told you allready about it.

Whats the solution now? 

Can the version 6.22.315 be downloaded somewhere ?

Thanks for answer
