NEW FEATURE: iRacing OAuth "Password Limited Grant" Authentication

• Allows authentication using "Client ID" and "Client Secret" issued by iRacing.

2502.0.0

NOTE:
iRacing has enabled two-factor authentication by default. To continue to use this library you must enable "Legacy Authentication" in your iRacing account settings before attempting to authenticate. Please do not enable this setting unless you require it, as it may reduce the security on your iRacing account.

FIXES:

• Implement Driver Award Instance (Issue #234)
• Resolve Awards Endpoint Parsing Issue - The result for the "Awards" endpoint seems to have changed. Update our code to handle that.

BREAKING CHANGES (as at version 2501.0.0):

• Removed .NET 6 support as it is now unsupported by Microsoft. (https://dotnet.microsoft.com/en-us/platform/support/policy/dotnet-core)

Please do not enable this setting unless you require it, as it may reduce the security on your iRacing account.

Fixes / Changes:

• Add "/data/stats/season_supersession_standings" Endpoint (Issue: #22)

• Unauthorized Responses Do Not Retry And Calls Continue To Fail (Issue: #231)

  • Implemented a retry mechanism for 401 Unauthorized responses
  • If a request fails with a 401 Unauthorized response, the library will attempt to re-authenticate and retry the request 2 more times
  • If the request continues to fail after 3 attempts, the library will throw an "iRacingUnauthorizedResponseException"

• Included .NET Diagnostics "Activity" for API Calls

  • All API calls are now wrapped in a .NET Diagnostics "Activity" to provide more detailed information in the logs
  • This will allow you to see the duration of the API call, the endpoint that was called, and the status code of the response
  • See "Distributed Tracing" on Microsoft Learn for more information: https://learn.microsoft.com/en-au/dotnet/core/diagnostics/distributed-tracing

• DriverResult is missing the CountryCode property (Issue #228)

2404.2.1

Fixes / Changes:

• Season Driver Standings Deserialization Failure (Issue #224)
  Fixed an issue where the "SeasonDriverStandings" deserialization would fail
  due to the "avg_start_position" property containing non-integer data.

• Support "Legacy Authentication" Setting Failure Response (Issue #223)
  Added support for the "Legacy Authentication" setting in the iRacing
  account settings. This setting will be required to login to the
  "/data API" after iRacing enables multi-factor authentication (aka "2FA").

  If the setting is not enabled, an "iRacingLoginFailedException" will be
  thrown when attempting to login with the new "LegacyAuthenticationRequired"
  property set to "true" and the following message:

  Access was denied with message "legacy authorization refused"
