    • Local errors inherit the LocalError interface, which inherits the LibraryError interface
  • Common error messages are now available as constants for parsing (e.g. regex)
• All uses of *time.Time have been replaced with new easypost.DateTime class
  • DateTime is a wrapper around time.Time that handles unexpected date formats from the API
• Previously-marked deprecated functions and structs have been removed:
  • ListReportOptions struct -> use ListOptions struct instead
  • Beta carrier metadata functions -> use non-beta functions instead
  • LowestRate shipment functions -> use LowestShipmentRate functions instead
  • CreateWebhook function -> use CreateWebhookWithDetails function instead
  • EnableWebhook function -> use UpdateWebhook function instead
• TrackingCodes string array on ListTrackersOptions struct is now TrackingCode single string
• AddShipmentsToBatch and RemoveShipmentsFromBatch functions now explicitly accept Shipment structs instead of generic interface{} types
  • Functions will no longer accept solely IDs; users will need to provide whole Shipment structs
