MySQL Connector/ODBC 5.3.10 has been released

MySQL Connector/ODBC 5.3.10, 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).

Also, Connector/ODBC 5.3 introduces a GTK+-based setup library providing a GUI DSN setup dialog on some Unix-based systems, currently included in the Debian 7/8/9, EL6/OL6, EL7/OL7 (64-bit only), Fedora 24/25/26, FreeBSD 10/11, SLES 12, Ubuntu 14/16/17 packages. Other new features in the 5.3 driver are FileDSN and Bookmarks support.

The release is now available in source and binary form for a number of platforms from our download pages at
