      • The maximum supported length of identifiers has been increased to 128 bytes when connecting to Oracle 12c R2 (12.2) databases. This change has been implemented to reflect the new maximum length supported by the server.
      Changed Behavior 
      • The product package no longer includes the ODBC Cursor library file (odbccurs.so) because it has some known security vulnerabilities that could potentially expose you to security risks.*
        Note: The installer program cannot remove the ODBC Cursor library file automatically while installing a new version of the driver. Remove it manually.
      • The valid value for the Authentication Method (AuthenticationMethod) option for retrieving credential information from Oracle Wallet password stores has been changed from 14 to 16. To support existing configurations of the driver, the original value, 14, will continue to be supported for this version of the driver. See for Authentication Method for details.
      • 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.

      • 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 default value for the Data Integrity Types connection option has changed to the following: MD5,SHA1,SHA256,SHA384,SHA512. Refer to Data Integrity Types for details.

        • Support for returning implicit result sets from stored procedures.
        • The driver is now compiled using Visual Studio 2015 for improved security.
        • The new SDU Size connection option allows you to specify the size in bytes of the Session Data Unit (SDU) that the driver requests when connecting to the server.
        • The new Support Binary XML connection option enables the driver to support XMLType with binary storage on servers running Oracle 12c and higher. 
        • The new LOB Prefetch Size connection option allows you to specify the size of prefetch data the driver returns for BLOBs and CLOBs for Oracle database versions 12.1.0.1 and higher. With LOB prefetch enabled, the driver can return LOB meta-data and the beginning of LOB data along with the LOB locator during a fetch operation. This can have significant performance impact, especially for small LOBs which can potentially be entirely prefetched, because the data is available without having to go through the LOB protocol.
        Changed Behavior 
        • The Enable N-CHAR Support connection option has been deprecated, and the driver behavior has been updated to always provide support for the N-types NCHAR, NVARCHAR2 and NCLOB. For compatibility purposes, the EnableNcharSupport attribute can still be manually specified for this release, but will be deprecated in subsequent versions of the product. 
        • The Enable Timestamp with Timezone connection option has been deprecated, and the driver behavior has been updated to always expose timestamps with timezones to the application. For compatibility purposes, the EnableTimestampwithTimezone attribute can still be manually specified for this release, but it will be deprecated in subsequent versions of the product.
        • The default value for the Data Integrity Level connection option has been updated to 1 (Accepted). By default, a data integrity check can now be made on data sent between the driver and the database server, if the server request or requires it. This change allows the driver to connect to servers requiring Oracle Advanced Security data integrity checks using the default configuration.
        • The default value for the Encryption Level connection option has been updated to 1 (Accepted). By default, encryption is now used on data sent between the driver and the database server if the database server requests or requires it. This change allows the driver to connect to servers requiring Oracle Advanced Security encryption using the default configuration.
