Test your ODEsolve.

Jean, you can do it yourself. There are no changes in the numerical solvers yet. Therefore, it makes no sense to repeat the same thing. The block I added doesn't do any calculations. All old numerical methods are used. There are no new numerical solvers.

If you really want to help test the solvers, then translate these 295 examples from Mathcad to SMath Studio:
