I get this padstasck : 

In 2021.04, with the same values, I get this message : "Pads were trimmed to clear the body."
and pads are like this : 

Please could you explain to me what is the difference ? what is the new calculation and why ?
What means""Pads were trimmed to clear the body."?

In V2021.04 pads are being trimmed for Gull wing lead parts when the A1 package stand-off is less than 0.03. 

You can change this in Tools > Options > Pad Stack Rules > SMD Minimum Trim and Spacings > Minimum Trim Stand-off Height. > 0.03 

Change to 0.00 if you want to leave the pads under a package that has no standoff.
