The available versions method is indeed gone. Versions are now retrieved from the container image. If a user wants to use a different version of the model, they can specify the container image like this:

from ewatercycle.container import ContainerImage

ewatercycle.models.MarrmotM14(
    forcing=forcing,
    bmi_image=ContainerImage("ewatercycle/marrmot-grpc4bmi:2020.11")  # change the tag to a different version
)
