 ## Next Release
 
+- Adds new `shipment.recommend_ship_date`, `smartrate.recommend_ship_date`, and `smartrate.estimate_delivery_date` functions
 - Routes `UpsAccount`, `UpsMailInnovationsAccount`, and `UpsSurepostAccount` create/update requests to the new `/ups_oauth_registrations` endpoint
   - Starting `2024-08-05`, UPS accounts will require a new payload to register or update. See [UPS OAuth 2.0 Update](https://support.easypost.com/hc/en-us/articles/26635027512717-UPS-OAuth-2-0-Update?utm_medium=email&_hsenc=p2ANqtz-96MmFtWICOzy9sKRbbcZSiMovZSrY3MSX1_bgY9N3f9yLVfWQdLhjAGq-SmNcOnDIS6GYhZ0OApjDBrGkKyLLMx1z6_TFOVp6-wllhEFQINrkuRuc&_hsmi=313130292&utm_content=313130292&utm_source=hs_email) for more details
