Prerelease: no

Release notes:

Added

• Added the EnableTokenFederation url param to enable or disable Token federation feature. By default it is set to 1
• Added the ApiRetriableHttpCodes, ApiRetryTimeout url params to enable retries for specific HTTP codes irrespective of Retry-After header. By default the HTTP codes list is empty.

Updated

• Added validation for positive integer configuration properties (RowsFetchedPerBlock, BatchInsertSize, etc.) to prevent hangs and errors when set to zero or negative values.
• Updated Circuit breaker to be triggered by 429 errors too.
• Refactored chunk download to keep a sliding window of chunk links. The window advances as the main thread consumes chunks. These changes can be enabled using the connection property EnableStreamingChunkProvider=1. The changes are expected to make chunk download faster and robust.
• Added separate circuit breaker to handle 429 from SQL Exec API connection creation calls, and fall back to Thrift.

Fixed

• Fix driver crash when using INTERVAL types.
• Fix connection failure in restricted environments when LogLevel.OFF is used.
• Fix U2M by including SDK OAuth HTML callback resources.
• Fix microsecond precision loss in PreparedStatement.setTimestamp(int,Timestamp, Calendar) and address thread-safety issues with global timezone modification.
• Fix metadata methods (getColumns, getFunctions, getPrimaryKeys, getImportedKeys) to return empty ResultSets instead of throwing exceptions when catalog parameter is NULL, for SQL Exec API.
