Plugin "Premium Shipping" error

Hello,

After upgrading to the version 1.11.8 we get this message from the Premium Shipping plug-in:

“The plugin “Premium Shipping” only works with Jigoshop 1.4 or better. Please upgrade Jigoshop to use this plug-in.”

Are there not updates for this plug-in? What happens?

Regards
Christel
