In Connector/ODBC 8.0.26, the capability was introduced for applications that use the classic MySQL connections for accounts that use the
authentication_kerberosserver-side authentication plugin, provided that the correct Kerberos tickets are available or can be obtained from Kerberos. That capability was available on client hosts running Linux only. It is now available on client hosts running Windows.
For more information about Kerberos authentication, see Kerberos Pluggable Authentication.
Changed the NO_SCHEMA default value from 0 to 1. It's enabled to behave like in the older versions the ODBC driver to not accept schema parameters and not declare support for schema functions. (Bug #33300344)
The MSI installation package did not install plugin libraries present in the Zip package, such as fido_client, kerberos_client, and ldap_sasl_client. (Bug #33269861)
Fixed the internal character set conversions of string data inside the driver; some UTF8MB4 characters were not properly converted. (Bug #33241697, Bug #104346)
The ODBC driver can now load plugins from their default location without need to specify the plugins directory using the PLUGIN_DIR connection option. (Bug #33134373)
Added logic to correctly detect OUT/INOUT parameters from a stored procedure, as a workaround to a libmysqlclient issue. (Bug #30578291)
The second call to a stored procedure failed if the statement was closed after the results of the first call had been received. (Bug #29042032, Bug #93378)
