    is the version shipped with Debian and Ubuntu. (Bug #32685)
  * Disallow 'SET NAMES' in initial statement and in executed statements.
  * Replaced the internal library which handles creation and loading

    unavailable from subsequent calls to SQLGetDiagRec().
  * ADO was unable to open record set using dynamic cursor. (Bug #32014)
  * SQLSetConnectAttr() did not clear previous errors, possibly confusing
    SQLError().
  * SQLDescribeColW returned UTF-8 column as SQL_VARCHAR instead of 
    SQL_WVARCHAR. (Bug #32161)
  * Fixed SQL_ATTR_PARAM_BIND_OFFSET, and fixed row offsets to work
    with updatable cursors.
  * SQLSetPos w/SQL_DELETE advances dynamic cursor incorrectly. (Bug #29765)
  * Recordset Update() fails in 5.1 ODBC connector when using adUseClient
    cursor. (Bug #26985)
