Enhancements

• 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. The default setting is BatchMechanism=1 (SingleRowInsert).
• The default version of the OpenSSL library has been upgraded to version 1.1.1l, which fixes the following security vulnerabilities:*
  • SM2 Decryption Buffer Overflow (CVE-2021-3711)
  • Read buffer overruns processing ASN.1 strings (CVE-2021-3712)

  Version 1.1.1l 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.

• OpenSSL library 1.1.1k has been replaced with version 1.1.1l. In addition to fixing multiple new vulnerabilities, version 1.1.1l also addresses the vulnerabilities resolved by version 1.1.1k:* 
  • CA certificate check bypass with X509_V_FLAG_X509_STRICT (CVE-2021-3450)
  • NULL pointer deref in signature_algorithms processing (CVE-2021-3449)
  • Null pointer deref in X509_issuer_and_serial_hash() (CVE-2021-23841)
  • Integer overflow in CipherUpdate (CVE-2021-23840) 
• OpenSSL library 1.1.1i has been replaced with version 1.1.1l. In addition to fixing multiple new vulnerabilities, version 1.1.1l also addresses the vulnerability resolved by version 1.1.1i: Incorrect behavior of the GENERAL_NAME_cmp function (CVE-2020-1971).*
• OpenSSL library 1.1.1g has been replaced with version 1.1.1l. In addition to fixing multiple new vulnerabilities, version 1.1.1l also addresses the vulnerabilities resolved by version 1.1.1g:*
  • Segmentation fault in SSL_check_chain (CVE-2020-1967)
  • rsaz_512_sqr overflow bug on x86_64 (CVE-2019-1551)  
• 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.*
• OpenSSL library 1.0.2r has been replaced with version 1.0.2u. In addition to fixing multiple new vulnerabilities, version 1.0.2u also addresses the vulnerabilities resolved by version 1.0.2r.*
  Version 1.0.2u of the OpenSSL library fixes the following security vulnerabilities:
  • x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli (CVE-2019-1563)
  • Padding Oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey (CVE-2019-1563)
  • Compute ECC cofactors if not provided during EC_GROUP construction (CVE-2019-1547)
  • Installation paths in diverse Windows builds (CVE-2019-1552)

  Note: By default, the driver will attempt to load version 1.1.1 of the library; however, if the library cannot be loaded, the driver will fall back to version 1.0.2.

• 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.
• A Power BI connector is now included with the product package. You can use this connector to access your Greenplum data with Power BI.*
• The default OpenSSL library version has been updated to 1.1.1d.*
• 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.
• The default OpenSSL library version has been updated to 1.0.2r.*
• The default OpenSSL library version has been updated to 1.0.2n.*
• The default OpenSSL library version has been updated to 1.0.2k.*
• The default OpenSSL library version has been updated to 1.0.2j.* .
• The default OpenSSL library version has been updated to 1.0.2h.* 
• The default OpenSSL library version has been updated to 1.0.2g.*
• The default OpenSSL library version has been updated to 1.0.2f.
• The new CryptoLibName and SSLLibName connection options allow you to 
   designate the OpenSSL libraries used when SSL is enabled.
• The driver has been enhanced to support Kerberos Authentication. 

Changed Behavior

• 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)
• The AuthenticationMethod connection option has been refreshed with a new valid value for enabling Kerberos Authentication. To use Kerberos  authentication with the driver, set AuthenticationMethod=4.
