The version 9.0 distribution includes only the single user code, and does not include the ODBC driver. In the previous version, the ODBC driver was part of the client/server code, and ODBC was only available in client/server mode. For version 9.0, we have changed the design so that ODBC can be used in both single user and client/server mode. We expect to post the next release, including the ODBC driver, about June 1. (Dates are, as always, approximations.) The following release, about July 1, will include the client/server code.
