Woocommerce -- where has 'Additional Rates' (Flat Rate Shipping) gone?

Hi there,
I have installed the latest woocommerce and transferring all my old site to the new platform. But I cannot find ‘Additional Rates’ in the Flat Rate / Shipping section. I use this to allow my customers the ability to select the normal flat rate or an express post option. I used this code in the Additional Rates field: Express Post | 1.40 | Per Order

Can anyone tell me where I put this code now to give customer the option of flat rate and express shipping please?
