[ashish-greycube]

Hello Team,
https://developer-docs.amazon.com/sp-api/docs/fulfillment-inbound-api-v2024-03-20-reference
has many new API ex PlacementOptions , TransportationOptions. To createinbound
in fact there is warning
All operations other than getLabels, getBillOfLading, and getPrepInstructions are deprecated and will be removed on December 20, 2024.
Latest v1.4.3 of python-amazon-sp-api (19th march) doesn't have it
I am eager to know when we would have api-v2024-03-20 as they are breaking changes
Please advise thanks
