Support and Certifications

Changes Since 8.0.2 GA

• Driver Enhancements
  • The default version of the OpenSSL library has been upgraded to 3.5.6. As part of this upgrade, earlier version of the OpenSSL 3.0 library continues to be supported to provide the best protection for your data. The upgrade is available in the following OpenSSL library files:
    • Windows: ivopenssl.dll and ddopenssl.dll
    • Unix: ivopenssl.so and ddopenssl.so
  • The driver is now compiled with a Visual Studio 2022 compiler for the Windows platforms. As a result, you must have Microsoft Visual C/C++ runtime version 14.40.33810 or higher on your machine to run the driver.
  • The default version of the OpenSSL library has been upgraded to 3.0. As part of this upgrade, earlier versions of the OpenSSL library are no longer supported to provide the best protection for your data. The upgrade is available in the following OpenSSL library files: xxopenssl30.dll (for Windows) and xxopenssl30.so [.sl] (for UNIX/Linux).

    The OpenSSL 3.0 library uses a set of shared libraries called providers to implement different types of cryptographic algorithms. The driver supports the following OpenSSL 3.0 providers: FIPS and default. See TLS/SSL server authentication and TLS/SSL client authentication for details.

  • The driver has been enhanced to support the Windows certificate store for TLS/SSL server authentication. See TLS/SSL server authentication for details.
  • The driver has been enhanced to support TLS/SSL server authentication for the applications deployed in a serverless environment. The driver stores the TLS/SSL certificates in memory and lets applications use TLS/SSL server authentication without storing the truststore file on the disk. To use this enhancement, specify the content of the certificate in the refreshed Trust Store (Truststore) connection option or the new SQL_COPT_INMEMORY_TRUSTSTORECERT pre-connection attribute. See Trust Store and Using SQL_COPT_INMEMORY_TRUSTSTORECERT for details.
  • The driver has been enhanced to support the JSON data type. See Data types for more information.
  • A Password Encryption Tool, called ddencpwd, is now included with the product package. It encrypts passwords for secure handling in connection strings and odbc.ini files. At connection, the driver decrypts these passwords and passes them to the data source as required. See Password Encryption Tool (UNIX/Linux only) for details.

Changes for 8.0.2 GA

• Driver Enhancements
  • The Allowed OpenSSL Versions (AllowedOpenSSLVersions) connection option has been deprecated.
  • The product no longer includes version 1.1.1 of the OpenSSL library. The library will reach the end of its product life cycle in September 2023 and will not receive any security updates after that. Note that continuing to use the library after September 2023 can potentially expose you to security vulnerabilities.
    Note: As a result of this change, when installing a new version of the product, the installer program will automatically remove version 1.1.1 of the library from the install directory, which will impact all the DataDirect ODBC drivers installed on a machine. Therefore, if you are using multiple drivers, upgrade all your drivers to the latest version.
  • The product no longer includes version 1.0.2 of the OpenSSL library. The library has reached the end of its product life cycle and is not receiving security updates anymore. Note that continuing to use the library could potentially expose you to security vulnerabilities.
    Note: As a result of this change, when installing a new version of the driver, the installer program will automatically remove version 1.0.2 of the library from the install directory.
  • The crypto protocol versions prior to TLSv1 are no longer supported.
  • The driver has been enhanced to support connecting to a proxy server through an HTTP connection. HTTP proxy support is configurable with five new connection options. See Proxy Host, Proxy Mode, Proxy Password, Proxy Port, and Proxy User for details.
  • A Power BI connector is now included with the product package. You can use this connector to access your MySQL data with Power BI. See Power BI (Windows only) for details.
  • The Batch Mechanism (BatchMechanism) connection option has been added to the driver. It determines the mechanism the driver uses to execute batch operations. See Batch Mechanism for details.
  • The driver has been enhanced to support the sha256_password and caching_sha2_password authentication plugins.
• Changed Behavior
  • Support has been deprecated for Linux on Intel Itanium II processor for the 64-bit version of the driver.
