 The following changelog shows what has been done in the 5.0 tree:
 
    * Basic support for read-only server side cursors. For information
      about using cursors within stored routines, see  cursors.
      For information about using cursors from within the C API, see
       mysql-stmt-attr-set.
 
    * Basic support for (updatable) views. See, for example, 
      create-view.
 
    * Basic support for stored procedures and functions (SQL:2003
      style). See  stored-procedures.
 
    * Initial support for rudimentary triggers.
 
    * Added `SELECT INTO LIST_OF_VARS', which can be of mixed (that is,
      global and local) types. See  select-into-statement.
 
    * Removed the update log. It is fully replaced by the binary log.
      If the MySQL server is started with -log-update, it is translated
      to -log-bin (or ignored if the server is explicitly started with
      -log-bin), and a warning message is written to the error log.
      Setting `SQL_LOG_UPDATE' silently sets `SQL_LOG_BIN' instead (or
      do nothing if the server is explicitly started with -log-bin).
 
    * Support for the `ISAM' storage engine has been removed. If you
      have `ISAM' tables, you should convert them before upgrading. See
       upgrading-from-4-1.
 
    * Support for `RAID' options in `MyISAM' tables has been removed. If
      you have tables that use these options, you should convert them
      before upgrading. See  upgrading-from-4-1.
 
    * User variable names are now case insensitive: If you do `SET
      @a=10;' then `SELECT @A;' now returns `10'. Case sensitivity of a
      variable's value depends on the collation of the value.
 
    * Strict mode, which in essence means that you get an error instead
      of a warning when inserting an incorrect value into a column. See
       server-sql-mode.
 
    * `VARCHAR' and `VARBINARY' columns remember end space. A
      `VARCHAR()' or `VARBINARY' column can contain up to 65,535
      characters or bytes, respectively.
 
    * `MEMORY' (`HEAP') tables can have `VARCHAR()' columns.
 
    * When using a constant string or a function that generates a string
      result in `CREATE ... SELECT', MySQL creates the result field
      based on the maximum length of the string or expression:
 
      *Maximum Length*        *Data type*
      = 0                     `CHAR(0)'
      < 512                   `VARCHAR(MAX_LENGTH)'
      >= 512                  `TEXT'
