MySQL Connector/ODBC 5.3.11 has been released
Dear MySQL users,
MySQL Connector/ODBC 5.3.11, a new version of the ODBC driver for the MySQL database management system, has been released.
The available downloads include both a Unicode driver and an ANSI driver based on the same modern codebase. Please select the driver type you need based on the type of your application - Unicode or ANSI. Server-side prepared statements are enabled by default. It is suitable for use with any MySQL version from 5.5.
This is the fifth release of the MySQL ODBC driver conforming to the ODBC 3.8 specification. It contains implementations of key 3.8 features, including self-identification as a ODBC 3.8 driver, streaming of output parameters (supported for binary types only), and support of the SQL_ATTR_RESET_CONNECTION connection attribute (for the Unicode driver only).
The release is now available in source and binary form for a number of platforms from our download pages at
Changes in MySQL Connector/ODBC 5.3.11 (2018-07-30, General Availability)
Functionality Added or Changed
* Based on MySQL Client library 5.7.23 it has the support for the new caching_sha2_password authentication method, which allows connecting to MySQL Server 8.0.
* The Unicode version now uses the UTF8MB4 character set as a transport character set between the MySQL server and the ODBC driver. Because text conversions requested by the ODBC user with the CHARSET connection option are done inside the ODBC Driver after the data is received from the server, it now converts text data as UTF8MB4 to USER_CHARSET instead of UTF8 to USER_CHARSET. (Bug #28204756)
* Connections to MySQL Server 8.0 could yield "Source character set not supported by client" errors during sorting and case-sensitive operations. Now known UTF8MB4 collations are used for these operations, such as utf8mb4_general_ci (known to libmysqlclient 5.7) instead of utf8mb4_tolower_ci. (Bug #28116892, Bug #90984)
* MySQL Server 8.0 connections could fail with unsupported character sets and collations as utf8mb4_xxxxxx collations reported by MySQL Server 8.0 with numbers greater than 250 were unknown to libmysqlclient 5.7. Because collations affect sorting but not the data conversion, they can be substituted with known collations such as utf8mb4_general_ci (45). (Bug #28116892, Bug #90984)
* Connector/ODBC is now built with MySQL client library 5.7.23, and commercial builds also use an updated OpenSSL version (v1.0.2o). Issues fixed in the new OpenSSL version are described at http://www.openssl.org/news/vulnerabilities.html. (Bug #27829777)
* Reported errors that occurred while executing multiple statements with a single query were generic and without context. For example, SQLMoreResults might return "unhandled error from mysql_next_result()" instead of the error reported by MySQL Server. (Bug #11757423, Bug #49466)
