(I cannot use 3.10.3 at the moment due to > compatibilty with a third library), What compatibility problem is this? 3.10.3 should be (binary and source) backward compatible with other 3.10 releases, so if there is a case where it is not, we need to understand it. Regarding the event, it seems there are scenarios where something important changes in the model and a conservative time step is desirable, and other scenarios where the dynamics after the event are on the same scale as before so it makes sense to continue with the same step sizes.
