cvxpy 1.1.7 no longer compatible with numpy<1.20?

I use python 3.7.9 with cvxpy 1.1.7 and numpy 1.18.1.

However as of Sunday we get an error message that the module is compiled with a newer numpy version. Before the weekend everything was still working.



What happened on sunday 31 january that this throws an error now?

Issue is resolved by upgrading numpy to 1.20, however isnt cvxpy supposed to support numpy>1.15? I want to stay on 1.18.1 still.
