What's Changed

• Drop support for Go 1.15
  • Minimum supported version is now Go 1.16
• Adds specific error types for API and local errors
  • All errors inherit the LibraryError interface
    • API errors inherit the APIError interface, which inherits the LibraryError interface
    • 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

Please view our Upgrade Guide for details on how to upgrade from 2.x to 3.0.

v2.15.0

• Adds BetaGetCarrierMetadata, BetaGetCarrierMetadataWithCarriers, BetaGetCarrierMetadataWithTypes, and BetaGetCarrierMetadataWithCarriersAndTypes function
• The Message attribute of an APIError is now an interface{} rather than a string, due to potential inconsistent data structure from the API response
  • Behind-the-scenes, the message portion of the JSON response is transformed to a concatenated string. Users should be able to safely cast the Message attribute to a string when accessing it via myApiError.Message.(string)
