Enhancements

• The installer program has been enhanced to support Azul Zulu JRE 11. As a result of this change, the installer has ended support for platforms that do not support Java SE 8 or higher. The installer supports the following operating systems after the enhancement:
  • Windows 8.1 or higher
  • Windows Server 2012 RC2 or higher
  • 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.
  Important: These changes do not affect the operating system requirements of the driver.*
• The default version of the OpenSSL library has been upgraded to version 1.1.1t, which fixes the following security vulnerabilities:*
  • X.400 address type confusion in X.509 GeneralName (CVE-2023-0286)
  • Use-after-free following BIO_new_NDEF (CVE-2023-0215)
  • Double free after calling PEM_read_bio_ex (CVE-2022-4450)
  • Timing Oracle in RSA Decryption (CVE-2022-4304)

  Version 1.1.1t also addresses vulnerabilities resolved by earlier versions of the library. For more information on the installed library files, refer to the readme.
  For more information on the OpenSSL vulnerabilities resolved by this upgrade, refer to the corresponding OpenSSL announcements at https://www.openssl.org/news/vulnerabilities-1.1.1.html.

• The curl library files that are installed with the product have been upgraded to version 7.88.1, which fixes a number of potential security vulnerabilities. For more information on the vulnerabilities resolved by this enhancement, refer to: https://curl.haxx.se/docs/vulnerabilities.html.
  This upgrade is available starting in build 08.02.0693 of the curl library files.*
• The curl library files that are installed with the product have been upgraded to version 7.84.0, which fixes a number of potential security vulnerabilities. For more information on the vulnerabilities resolved by this enhancement, refer to: https://curl.haxx.se/docs/vulnerabilities.html. This upgrade is available starting in build 08.02.0435 of the curl library files.*
• The driver has been enhanced to support the Windows certificate store for TLS/SSL server authentication. Refer to the user's guide 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. Refer to the user's guide for details.*
• The Batch Mechanism (BatchMechanism) connection option has been enhanced to support the native batch protocol for batch inserts. When BatchMechanism is set to 4 (NativeBatch), the driver uses the native batch protocol for the insert operation of all batched parameters. For update and delete batch operations, the driver uses the native batch mechanism by default to handle the request.*
• OpenSSL library 1.1.1n has been replaced with version 1.1.1t. In addition to fixing multiple new vulnerabilities, version 1.1.1t also addresses the vulnerabilities resolved by version 1.1.1n:*
  • Infinite loop in BN_mod_sqrt() reachable when parsing certificates (CVE-2022-0778)
  • BN_mod_exp may produce incorrect results on MIPS (CVE-2021-4160)
• The curl library files that are installed with the product have been upgraded to version 7.80.0, which fixes a number of potential security vulnerabilities. For more information on the vulnerabilities resolved by this enhancement, refer to: https://curl.haxx.se/docs/vulnerabilities.html.*
  This upgrade is available starting in build 08.02.0278 of the curl library files.
• The Use Declare Fetch (UseDeclareFetch) and Fetch Size (FetchSize) connection options have been added to the driver. The Use Declare Fetch option determines whether the driver attempts to return a result set in a single fetch or across multiple fetches. If multiple fetches are used, the setting of the Fetch Size option determines the size of each fetch. For large result sets, retrieving rows in multiple fetches can improve response time and thereby prevent possible timeouts. Refer to the user's guide for details.*
• OpenSSL library 1.1.1l has been replaced with version 1.1.1n. In addition to fixing multiple new vulnerabilities, version 1.1.1n also addresses the vulnerabilities resolved by version 1.1.1l:* 
  • SM2 Decryption Buffer Overflow (CVE-2021-3711)
  • Read buffer overruns processing ASN.1 strings (CVE-2021-3712)
• The driver has been enhanced to support stored procedures for PostgreSQL 11 and later.
• The Call Escape Behavior (CallEscapeBehavior) connection option has been added to the driver. The driver determines whether to call a user-defined function or a stored procedure based on the value specified for this option.
• The driver has been enhanced to support certificate-based authentication. It uses TLS/SSL protocol for authentication and authenticates the client to the server if the TLS/SSL client certificate is issued by a trusted Certificate Authority (CA) and the Common Name (cn) attribute of the TLS/SSL client certificate matches the database user name. Two new connection options, Client SSL Certificate and Client SSL Key, have been added to support this authentication method. Refer to the user's guide for details.
• The Show Selectable Tables (ShowSelectableTables) connection option has been added to the driver. It determines whether the driver returns metadata for all tables or only for the tables for which the user has Select privileges. It can help the users with restricted Select privileges retrieve metadata for the required tables.
• The driver has been enhanced to support the SCRAM-SHA-256-PLUS authentication method, which uses channel binding for establishing a secure connection with PostgreSQL (v11.0 and higher).
• The driver has been enhanced with the new Batch Mechanism (BatchMechanism) connection option, which specifies the preferred mechanism for executing batch insert operations. By setting Batch Mechanism to 2 (MultiRowInsert) or 3 (Copy), the driver can achieve substantial performance gains when performing batch inserts. Refer to the user's guide for details. 
• The driver has been enhanced to support the following data types: Citext, Float, and Tinyint.
• The drivers using base version B0649 and later have been enhanced to include timestamp in the internal packet logs by default. If you want to disable the timestamp logging in packet logs, set PacketLoggingOptions=1. The internal packet logging is not enabled by default. To enable it, set EnablePacketLogging=1.
• The Driver Manager for UNIX/Linux has been enhanced to support setting the Unicode encoding type for applications on a per connection basis. By passing a value for the SQL_ATTR_APP_UNICODE_TYPE attribute using SQLSetConnectAttr, your application can specify the encoding at connection. This allows your application to pass both UTF-8 and UTF-16 encoded strings with a single environment handle.
  The valid values for the SQL_ATTR_APP_UNICODE_TYPE attribute are SQL_DD_CP_UTF8 and SQL_DD_CP_UTF16. The default value is SQL_DD_CP_UTF8.
  This enhancement is available in build 07.16.0398 of the driver manager.
• The new AllowedOpenSSLVersions option determines which version of the OpenSSL library file the driver uses for data encryption when multiple versions are installed with the product. For example, when specifying a value of 1.1.1 (AllowedOpenSSLVersions=1.1.1) the driver uses the 1.1.1 version of the library that is installed with the driver.
• A Power BI connector is now included with the product package. You can use this connector to access your PostgreSQL data with Power BI. Refer to the user's guide for details.
• The driver has been enhanced to support Select queries with parameterized arrays.
• The driver has been enhanced to support md5 and scram-sha-256 authentication methods.
• The driver has been enhanced to support materialized views and foreign tables.

Changed Behavior

• For PostgreSQL 9.0 and later, the driver behavior has been updated to support executing multiple prepared statements in a single query that contain inserts for BYTEA values. However, for versions earlier than PostgreSQL 9.0, this functionality is not supported and the driver returns an error.
• The default value for the Batch Mechanism (BatchMechanism) connection option has been changed to 3 (Copy). The driver now, by default, uses the PostgreSQL COPY command to insert rows into the target table. It allows the driver to achieve substantial performance improvements over 1 (SingleRowInsert) when performing batch inserts. Refer to the user's guide for details.
• Support has been deprecated for HP-UX IPF and HP-UX PA-RISC platforms.
• The following Windows platforms have reached the end of their product lifecycle and are no longer supported by the driver:
  • Windows 8.0 (versions 8.1 and higher are still supported)
  • Windows Vista (all versions)
  • Windows XP (all versions)
  • Windows Server 2003 (all versions)
