3.51.05 Release Candidate (27-Feb-2003)

  Functionality added or changed:
  * Return the DRIVER name when no DSN is specified
  * Added support for new autoconf tools
  * Added scripts for producing binary distributions and source snapshots

    privilege type in a distinct row

    to Ocke Janssen from Sun)
  * Fixed core dump on HP-UX in SQLSpecialColumns()
  * Fixed SQLGetTypeInfo to return individual rows for auto_increment
    status for all numeric types (requested by Gerry Sweeney)

    to handle SQL_NUMERIC_STRUCT conversion due to the lack of descriptors
    support.  (Requested by Michael Thomas of Microsoft's ODBC team)

    forward-only cursors.
  * Added options to ./configure to control whether to use the thread-safe
    client library
  * Cleaned up thread-safe code (debug calls)
  * Added checks for attempts to set pre-connection attributes (AUTOCOMMIT,
    TXN_ISOLATION) values after the connection instead of returning error
    when they are set before the connection
  * Added two new options, 'Force use of forward-only cursors' 
    and 'Don't cache results', to help large-scale applications
  * Made improvements to driver logging calls (myodbc.log and myodbc.sql)

  * Fixed SQLTables() to not return an data related to SYSTEM TABLES
  * Fixed core dumps on HP-UX and AIX

  * Fixed rs.update when server-side cursors are used
   
----

  * Added new DSN configuration dialog window
  * Added support for SQLForeignKeys() for InnoDB tables
  * Added support for new Query Log eoption, which allows the driver
    to log all SQL queries that it processes
  * Added code for one-time initialization when ODBC version is specified
    as SQL_OV_ODBC2 so that subsequent calls will not check ODBC version
  * Added MY_SQL_PRIMARY_KEY(1212) option to SQLColAttribute to make
    rs.resync work from ADO (info from Dan Perik)

  Bugs fixed:
  * Fixed multi-step generated errors when server-side cursor is used
    (Thanks to [e-mail] and AdoAnywhere)

    from Microsoft Access and Microsoft DTS to MySQL using MyODBC.
  * Fixed to handle SQL_C_BINARY properly (info from Spilka)

    cases (info from akbar ali)
  * Fixed type casting issues in SQLGetInfo to make OpenOffice.org
    work (reported by Ocke Janssen)
  * Fixed SQLFetch() when it is called after SQLFetchScroll() with
    SQL_FETCH_FIRST (reported by Simone Tregnago)
  * Mapped SQL_ATTR_CONNECTION_TIMEOUT option to mysql_options() with
    MYSQL_OPT_CONNECT_TIMEOUT
   
----

3.51.02 (05-Mar-2002)

  Functionality added or changed:
  * Added support for SQLTablePrivileges() and SQLColumnPrivileges()
   
  Bugs fixed:
  * Fixed SQLDriverConnect() to return  correct output string. This is
    the main fix for 'Reserved error (-7778)' from all Windows ODBC
    applications.
  * Fixed SQLError() to clear the error buffers on the first call when
    the ODBC version is SQL_OV_ODBC3, so subsequent calls will return
    SQL_NO_DATA.
  * Fixed SQL_UPDATE and SQL_ADD from SQLSetPos().
  * Fixed SQLSetPos() and SQLBulkOperations() to handle when the 
    application passes SQL_NTS as pcbValue
  * Fixed SQLColumns() to return the correct Nullability

    SQLExpress for XBase++ and .NET connection closed issues

    SQL_TYPE_DATE, SQL_TIME, SQL_TYPE_TIME, SQL_TIMESTAMP, and
