Mysterious pads on Nucleo64 and Nucleo144

A Nucleo144 landed on my desk. As with every new board, there has been a stare-and-criticize session, and somebody noticed four pads at the four corners of the chip, at a 45 deg. angle. They are roughly of 0805 size and full of solder.

I have looked at the Nucleo64 UM and they are there, too. Not on the Nucleo32.

Anybody knows the purpose of these?
