Nothing changed in 4.11 in terms of ground effect. What you're experiencing there is what's called "Placebo"
But, to be more to the point, you're likely going too fast. I tend to make an approach with ~30% power with a collision course with the runway threshold. A few meters over the ground, I pull up, and reduce power simultaneously. The plane slows and stalls onto the runway, resulting in a 3-pointer each time.
