    • Product Compatibility Guide: Provides the latest data source and platform support information. 
    • Fixes: Describes the issues resolved since general availability.  

    Version 6.0.0

    • The driver has been modified to map Snowflake data types for fixed-point numbers to the Numeric data type by default. In addition, the IntegerFieldMapping connection property has been added to the driver. This connection property allows you specify whether fixed-point numbers are mapped to Numeric or BigInt. Refer to IntegerFieldMapping and Data Types.*
      • Available: Driver version (C5756.F002097.U001111)
    • The driver has been enhanced to support the refresh token grant for OAuth 2.0 authentication. To support it, a new connection property, RefreshToken, has been added. Refer to the user's guide for details. Refer to RefreshToken for details.*
      • Available: Driver version (C5325.F001946.U001044)
    • The driver has been enhanced to fall back to JSON query format when the arrow format is not properly initialized. The driver uses a high-speed arrow transfer that requires the restricted APIs from java.nio package. When the JVM is not correctly configured for Java SE 16 and higher, an exception is returned when the driver executes a query. To allow you to continue executing queries in this scenario, you can configure the new ArrowFallbackToJson property to switch to the JSON query format. Refer to ArrowFallbackToJson for details.
    • The installer program has been enhanced to support Azul Zulu JRE 11. As a result of this change, the installer has ended support for some of the old operating systems. The installer supports the following operating systems after the enhancement:*
      • UNIX/Linux:
        • Any operating system on a machine using a JRE that is Java SE 8 or higher (LTS version), including Oracle JDK, OpenJDK, and IBM SDK (Java) distributions.
      • Windows:
        • Windows 8.1 or higher
        • Windows Server 2012 RC2 or higher
      Important: These changes do not affect the operating system requirements of the driver.
