    Enhancements
    • 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 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.
    • 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 Batch Mechanism connection option has been added to the driver. When BatchMechanism is set to 2 (MultiRowInsert), the driver executes a single insert for all the rows contained in a parameter array. MultiRowInsert is the default setting and provides substantial performance gains when performing batch inserts.
    • The driver has been enhanced to support SSL encryption, which can be configured using the following new connection options: Crypto Protocol Version, CrypoLibName, Encryption Method, Host Name in Certificate, Key Password, Key Store, Key Store Password, SSLLibName, Trust Store, Trust Store Password, Validate Server Certificate. SSL support was formally certified against driver version 07.16.0317 (B0386, U0249).
    • Support for Kerberos Authentication.
    • The driver has been enhanced to support the Char, Decimal, and Varchar data
      types when connected to Impala 2.0 and higher.
    • The ArraySize connection option has been refreshed to allow specifying
      the number of cells retrieved instead of rows. By determining the fetch size
      based on the number of cells, the driver can avoid out of memory errors when
      fetching from tables containing a large number of columns.
    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.

    Version 7.1.5

    Certifications
    • Certified with Red Hat Enterprise 7.0
    • Certified with CentOS Linux 7.0
    • Certified with Oracle Linux 7.0
    • Certified with Cloudera Impala Server 1.1, 1.2, 1.3, 1.4
    • Certified with Cloudera Impala Server 2.0, 2.1

    Version 7.1.4

    Certifications
    • Certified with Windows 8.1
    Enhancements
    • The new KeepAlive connection option allows you to use TCP Keep Alive to maintain idle TCP connections.

    Version 7.1.3

    Certifications
    • Certified with CentOS Linux 4.x, 5.x, and 6.x
    • Certified with Oracle Linux 4.x, 5.x, and 6.x

    Version 7.1.2

    Supported with the following Apache Hive versions:
    • Certified with Cloudera Impala 1.0 database server and formally certified with the following File formats and storage handlers:
      • File Formats:Parquet, Text File
      • Storage Handlers:HBase
    Features
    • Returns result set metadata for parameterized statements
      that have been prepared but not yet executed.
    • Supports parameter arrays, processing the arrays as a series of
      executions, one execution for each row in the array.
    • Provides a connection option that allows you to configure
      the driver to report that it supports transactions, although
      Hive does not support transactions. This provides a workaround
      for applications that do not operate with a driver that reports
      transactions are not supported.
    • Provides a connection option that allows you to set a default limit for
      the number of rows returned when an ORDER BY clause is submitted. This
      provides a workaround for applications that are not compatible with
      Impala's requirement that ORDER BY clauses limit the number of rows returned.
    •  The driver provides support for the following standard SQL
      functionality:
      • Create Index, Create Table, and Create View
      • Insert, Update, and Delete
      • Drop Index and Drop Table
