v4.4.0

• Added new beta RateService, accessible via myClient.Beta.Rate
• Added RetrieveStatelessRate function under beta RateService to pull stateless rates when shipment data is provided
• Added GetLowestStatelessRate function under Utilities.Rate to filter the lowest stateless rate
• Added new GetLowest instance functions, callable on List<Rate>, List<Smartrate> and List<StatelessRate>, to
  filter the lowest rate
• Deprecated rate and smartrate filtering methods in ShipmentService, RateService and Calculation.Rates namespaces, moved to Utilities.Rate namespace
• Fixes Strong-Name signing that was unintentionally removed in v4.1.0 (this package is now strong-name signed once again)

v4.3.0

• Added payload functions RetrieveAllPayloadsForEvent and RetrievePayloadForEvent methods, accessible via myClient.Event service.
• Added function to retrieve all pickups via myClient.Pickup.All()

v4.2.0

• Added new beta billing functionality for referral customer users, accessible via myClient.Beta.Referral service
  • AddPaymentMethod to add an existing Stripe bank account or credit card to your EasyPost account
  • RefundByAmount refunds you wallet balance by a specified amount
  • RefundByPaymentLog refunds you wallet balance by a specified payment log
• Added new DeliveryMaxDatetime Shipment option

v4.1.0

• Routes requests for creating a carrier account with a custom workflow (eg: FedEx, UPS) to the correct endpoint when using the Create function
• Constants are now stored in EasyPost.Constants instead of EasyPost.Exceptions.Constants
• Fixed a typo in /charges endpoint that was causing bank and credit card charge requests to fail

v4.0.2

• Fix bug where the temporary internal API key switch when adding a credit card to a referral user was not reverted after the request.
  • After adding a credit card to a referral user, the existing Client would be misconfigured for following requests.

v4.0.1

• myInsurance.Refresh() function HTTP method fixed from PATCH to GET
  • This function has been marked as obsolete and will be removed in a future release
• Fix return type of order.Buy() when passing in a rate. Function will now return the updated order.
• Fix bug where request time limits were not being copied to a cloned Client.
• Fix bug where hashcode of any EasyPostObject or subtype was not consistent.
  • Hashcode and equality now consider properties of the object, including Client. Different properties and/or different Clients will result in different hashcodes and objects will not be considered equal.
• Fix bug where the wrong SmartrateAccuracy would be chosen
  • Percentile75 might accidentally have been chosen rather than Percentile85 due to a bug in the SmartrateAccuracy enum ID.
• Fix bug where some embedded elements (e.g. customs items) were not being created if included during a larger creation request (e.g. customs info create).
• Prevent users from attempting to buy a shipment with a null rate, avoiding a NullReferenceException.

v4.0.0

Breaking Changes & New Features

• Library is now thread-safe
  • Initialize a Client object with an API key
  • Static methods (i.e. create, retrieve, retrieve all of a resource) exist in services, accessed via property of the client (e.g. myClient.Address.Create())
  • Instance methods (i.e. update, delete) accessed on instance of a resource (i.e. myShipment.Update())
• All properties are now title-cased rather than snake-cased to match standard .NET naming conventions
  • e.g. myShipment.id is now myShipment.Id, myAddress.federal_tax_id is now myAddress.FederalTaxId, myTrackerCollection.has_more is now myTrackerCollection.HasMore
  • Some properties have been renamed to avoid naming conflicts:
    • Rate.rate is now Rate.Price
    • Message.message is now Message.Text
• All properties are now nullable
  • Almost all properties will be assigned a value during JSON deserialization. This is mostly to address compiler warnings
  • Users can proceed with the assumption that any given property will not be null
• Consistent exception handling
  • All exceptions inherit from EasyPostError
  • API-related and HTTP-related exceptions will throw an ApiError or inherited-type exception
  • API exception types can be retrieved by HTTP status code via the EasyPost.Exceptions.Constants class (i.e. to anticipate what error will be thrown for a 404, etc.)
  • Common exception messages and templates can be found in the EasyPost.Exceptions.Constants class (i.e. for log parsing)
• Source code files have been organized
  • Most EasyPost-related objects (i.e. Shipment, Address, Tracker, etc.) are now in the EasyPost.Model.API namespace
• Dependencies updated to latest versions, including RestSharp v108

Misc

• Under the hood improvements:
  • Underlying Request-Client-ClientConfiguration relationship has been re-architected to allow for thread safety
  • Process of generating an API request has been standardized and simplified
  • Improved accessibility levels of internal functions, to prevent accidental use by end users
  • Files have been organized into a more logical structure
  • Methods and properties have been organized (e.g. methods ordered by CRUD, properties ordered alphabetically)
• Improved API error parsing
  • API error message may be an array rather than a string. Arrays will be concatenated (by comma) and returned as a string.
• Capture 1xx and 3xx HTTP status codes as errors
  • Any known 3xx status code from the EasyPost API will throw a RedirectError exception
  • Any unknown 3xx status code will throw a UnexpectedHttpError exception
  • Any 1xx status code (known or unknown) will throw a UnexpectedHttpError exception
