 # BigCommerce GraphQl Module Release Notes
 
+## bigcommerce-graphql-module-1.1.0
+
+#### Changes:
+
+- Updates the "generateMeshToken" function to return a "customer_id" property instead of "bc_customer_id". Updates the "getBcCustomerIdFromMeshToken" function to look for a "customer_id" property instead of "bc_customer_id". This is due to the Auth Module generating a JWT containing a "customer_id" property but the BigCommerce Module decodes the JWT and looks for a "bc_customer_id" property.
+
+#### Tickets
+
+- MI-121: Auth module authentication issue
+  - https://aligent.atlassian.net/browse/MI-121
