FVWM: change in focus follow mouse 2.6.8 to 2.7.0

I have just updated a laptop from (X)ubuntu 22.04 to 24.04 and this 
resulted in an update of fvwm from 2.6.8 to 2.7.0

I have noticed a change of behaviour (with the same .fvwrc). I am 
expecting focus following mouse movement. On 2.6.8 when I move the mouse 
into a partially obscured window, it gets focus and is raised to the top.

On 2.7.0 it gets focus but it not raised until I click on the title bar or 
borders.

Not sure which option did what I liked in 2.6.8, I suspect one of

ColormapFocus FollowsFocus
Style * SloppyFocus

Has it changed in 2.7.0 ?
Is there a new option to reinstate the old behaviour ?

Thanks
