MariaDB ODBC Driver 0.9.1 is a Beta release. In general this means that there are no known serious bugs, except for those marked as feature requests, but we feel it needs further testing and development before we call it stable.
MariaDB ODBC Driver 0.9.1 is built on top of the MariaDB LPGL C Client library and uses the binary prepared statement protocol.
Please, note that a beta version is NOT the final version of the product and we do not guarantee an absence of errors that may disrupt the computer's operation system and/or result data loss. We recommend against use of any beta software in a critical, commercial or production environment. Implementation of beta software should be limited to experienced users only in a staging or test environment.
