Impact on ODBC connectors

Hello

Our clients are currently using MariaDB 10.2 and use ODBC connectors provided by us to connect to the database. As 10.2 will run out of support by May next year, we intend to support a more recent version, 10.5 most probably. As its a leap of 3 versions, we understand that some things may break here and there which is perfectly normal in case of an upgrade. My question is, are there any major changes that may break or need considerable rework that we should expect with the upgrade? While we will definitely test our connector against 10.5 very soon, it will be good to know if there is something that we should expect.

Regards Abhishek
