3.2.1 ========================================================================

Release 2026-06-19

Enhancements & New Features

 * Updated third-party libraries

   The connector now uses the following third-party libraries:
   - LibCurl 8.20.0 (previously 8.19.0)
   - OpenSSL 3.5.7 (previously 3.0.20)
   - Expat 2.8.0 (previously 2.7.3)
   - Zlib 1.3.2 (previously 1.3.1)
   
Known Issues
The following are known issues that you may encounter due to limitations in
the data source, the connector, or an application.

 * The connector does not order the result sets for the following catalog
   functions:
     SQLColumns, SQLForeignKeys, SQLGetTypeInfo, SQLPrimaryKeys,
     SQLProcedureColumns, SQLProcedures, SQLTables

   This is a limitation in the ODBC driver discovered in July 2024.

 * The connector does not support parameterized types for Resultset and
   Parameter metadata.

   This is a limitation of the Google BigQuery server.

 * The connector does not support parameters in the exception block.

   This is a limitation of the Google BigQuery server discovered on Mar 2021.

 * On macOS or Linux platforms, when the connector converts SQL_DOUBLE data to
   SQL_C_CHAR or SQL_C_WCHAR, data which is small or large enough to require
   representation in scientific notation may prepend a 0 to the exponent.

   This is a limitation of Google BigQuery. For a list of BigQuery data types
   that the connector maps to the SQL_DOUBLE ODBC type, see the Installation
   and Configuration Guide.

 * When casting data, you must specify the data type according to Google
   BigQuery standards.

   When casting data to a specific data type, you must use the corresponding
   data type name shown in the "Casting" section of the Query Reference:
   https://cloud.google.com/bigquery/sql-reference/functions-and-operators#cas
   ting

   For example, to cast the "salary" column to the INTEGER type, you must
   specify INT64 instead of INTEGER:

      SELECT position, CAST(salary AS INT64) from Employee

 * When using the Standard SQL dialect, the connector's ODBC escape
   functionality is subject to the following limitations:

   - Standard SQL does not support the seed in the RAND([seed]) scalar
     function. As a result, the connector maps RAND() and RAND(6) to RAND().

   - For the following scalar functions, BigQuery only returns values in UTC,
     but ODBC expects the values in local time:
     - CURDATE()
     - CURRENT_DATE()
     - CURRENT_TIME[(TIME_PRECISION)]
     - CURRENT_TIMESTAMP[(TIME_PRECISION)]
     - CURTIME()
     - NOW()

   - Time precision values are not supported for the
     CURRENT_TIME[(TIME_PRECISION)] and CURRENT_TIMESTAMP[(TIME_PRECISION)]
     scalar functions.

   - TIME data types are not supported for the following scalar functions:
     - EXTRACT(interval FROM datetime)
     - TIMESTAMPADD(interval,integer_exp,timestamp_exp
     - TIMESTAMPDIFF(interval,timestamp_exp1,timestamp_exp2)
     For TIMESTAMPADD and TIMESTAMPDIFF, only the TIMESTAMP and DATE data
     types are supported.

   - When calling the TIMESTAMPADD() scalar function to work with DAY, WEEK,
     MONTH, QUARTER, or YEAR intervals, the connector escapes the function and
     calls DATE_ADD() instead. DATE_ADD() only supports DATE types, so time
     information is lost if the function is called on TIMESTAMP data.

   - When calling the TIMESTAMPDIFF() scalar function to work with DAY, MONTH,
     QUARTER, or YEAR intervals, the connector escapes the function and calls
     DATE_DIFF() instead. DATE_DIFF() only supports DATE types, so time
     information is lost if the function is called on TIMESTAMP data.

   - For the BIT_LENGTH scalar function, only the STRING and BYTES data types
     are supported. This behavior aligns with the SQL-92 specification, but
     not the ODBC specification.

 * When using the Legacy SQL dialect, the connector's ODBC escape
   functionality is subject to the following limitations:

   - For the following scalar functions, BigQuery only returns values in UTC,
     but ODBC expects the values in local time:
     - CURDATE()
     - CURRENT_DATE()
     - CURRENT_TIME[(TIME_PRECISION)]
     - CURRENT_TIMESTAMP[(TIME_PRECISION)]
     - CURTIME()

   - Time precision values are not supported for the
     CURRENT_TIME[(TIME_PRECISION)] and CURRENT_TIMESTAMP[(TIME_PRECISION)]
     scalar functions.

   - For the following scalar functions, TIME data types are not supported.
     Only the TIMESTAMP and DATE data types are supported.
     - TIMESTAMPADD(interval,integer_exp,timestamp_exp
     - TIMESTAMPDIFF(interval,timestamp_exp1,timestamp_exp2)

   Beginning with this release, the connector no longer supports macOS
   versions earlier than 10.14. For a list of supported macOS versions, see
   the Installation and Configuration Guide.


2.2.4 ------------------------------------------------------------------------

 * [GAUSS-980] Removed support for the Visual C++ Redistributable for Visual
   Studio 2013

   Beginning with this release, the driver no longer supports this version
   of the dependency, and requires Visual C++ Redistributable for Visual
   Studio 2015 instead.


2.2.2 ------------------------------------------------------------------------

 * [GAUSS-875] New service endpoints

   The driver now uses a new set of service endpoints to connect to the
   Google BigQuery API. The previous service endpoints have been deprecated.
   For a list of the new endpoints, see the "Service Endpoints" section of
   the Installation and Configuration Guide.

 * [GAUSS-897] Precedence for default large result dataset

   If the Use Default _bqodbc_temp_tables Large Results Dataset check box is
   selected (the UseDefaultLargeResultsDataset property is set to 1) and a
   dataset is specified in the Dataset Name For Large Result Sets field (the
   LargeResultsDataSetID property), the driver now uses the default
   _bqodbc_temp_tables dataset. For more information, see the Installation
   and Configuration Guide.


2.2.0 ------------------------------------------------------------------------

 * Linux support changes

   Beginning with this release, the Linux version of the driver now requires
   glibc 2.17 or later to be installed on the target machine.

   As a result, the driver no longer supports CentOS 6 or RedHat Enterprise
   Linux (RHEL) 6. Only CentOS 7, RHEL 7, and SUSE Linux Enterprise Server
   (SLES) 11 and 12 are supported.


2.1.22 -----------------------------------------------------------------------

 * [GAUSS-653] Updated large result set behavior

   The driver's behavior for handling large result sets with legacy SQL has
   been changed. When the driver sends a query, it checks whether the "Allow
   Large Results" option is enabled and if there is a dataset name specified.
   If the option is enabled, it requests a temporary large result set for
   your data. This data storage has cost implications for your Big Query
   account, consult the Big Query service documentation for details.


2.1.14 -----------------------------------------------------------------------

 * Minimum TLS Version

   Beginning with this release, the driver requires a minimum version of TLS
   for encrypting the data store connection. By default, the driver requires
   TLS version 1.2. This requirement may cause existing DSNs and connection
   strings to stop working, if they are used to connect to data stores that
   use a TLS version earlier than 1.2.

   To resolve this, in your DSN or connection string, set the Minimum TLS
   option (the Min_TLS property) to the appropriate version of TLS for your
   server. For more information, see the Installation and Configuration Guide.

 * Large result set handling

   If you have a default destination set for large datasets but have not
   enabled the Allow Large Result Sets option (the AllowLargeResults property)
   the driver reports an error.

   To resolve this, enable the Allow Large Result Sets option (the
   AllowLargeResults property).
