12.8.0-beta.1 (2021-07-22)

  • Added support for service version 2020-10-02.
  • Added support for Parquet as an input format in DataLakeFileClient.Query().
  • Added support for RequestConditions parameter validation. If a request condition is set for an API that doesn't support it, and ArguementException will be thrown.
    • This feature can be disabled with the environment variable "AZURE_STORAGE_DISABLE_REQUEST_CONDITIONS_VALIDATION" or the App Context switch "Azure.Storage.DisableRequestConditionsValidation".

  • Includes all features from 12.7.0-beta.4
  • Fixed bug where DataLakeFileClient.Read could corrupt data on retry.
  • Fixed bug where specifying "*" as IfMatch condition could lead to inconsistend read in DataLakeFileClient.ReadTo.
  • Fixed bug where specifying conditions in DataLakeFileClient.OpenRead could override allowModifications flag in DataLakeOpenReadOptions leading to inconsistent read.
  • TenantId can now be discovered through the service challenge response, when using a TokenCredential for authorization.
    • A new property is now available on the ClientOptions called EnableTenantDiscovery. If set to true, the client will attempt an initial unauthorized request to the service to prompt a challenge containing the tenantId hint.
