        Correct tests for ANY, SOME, ALL and EXISTS. 
        * tests/test-fdml.lisp: added test for COALESCE. 
        * sql/sql.lisp: MAP-QUERY now applies FUNCTION to QUERY-EXPRESSION 
        using funcall unless QUERY-EXPRESSION returns one column and its 
        FLATP slot is not nil in which case apply is used. 
        * tests/test-basic.lisp: modified calls to MAP-QUERY to reflect the 
        changes.

        upon the compilation options of unixODBC.
        * db-mysql/mysql-api.lisp: Fix int vs. long slots in foreign
        structures found by testing with AllegroCL 7.0b AMD64.

7 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * docs/intro.xml: Upload location of a README file
        * sql/metaclass.lisp: Work-around openmcl's CHANGE-CLASS
        changing the type-specifier. Use a lisp type of (OR NULL FOO)
        for a specified-type of FOO unless :db-constraints :not-null.
        No need to specialize finalize-inheritance for openmcl.
        * tests/test-*.lisp: Rename fields so that joins occur on
        fields with different names. This ensures that join code is
        selecting the proper name.
        * test/test-init.lisp: Add :base-table for employee-address
        view class for testing.
        * sql/objects.lisp: Use view-table rather than name of table

6 May 2004 Marcus Pearce (m.t.pearce@city.ac.uk) 
        * sql/objects.lisp: replace *update-records-on-make-instance* with 
        *db-auto-sync* which also controls both automatic creation of 
        new records on creation of new instance and updating of record 
        fields on setting of instance slots (as suggested by Edi Weitz). 
        * tests/test-init.lisp: replace *update-records-on-make-instance* 
        with *db-auto-sync*. 
        * sql/package.lisp: replace *update-records-on-make-instance* 
        with *db-auto-sync*. 
        * TODO: replace *update-records-on-make-instance* with *db-auto-sync*.

        * tests/test-init.lisp: replace CLSQl-BASE package qualifier with CLSQL. 
        * tests/test-ooddl.lisp: replace CLSQl-BASE package qualifier with 
        CLSQL. 

4 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * sql/classes.lisp: Add SQL-OBJECT-QUERY type. Have [select 'class]
        now return a sql-object-query type rather than directly performing a query.
        This improves CommonSQL conformance.
        * sql/sql.lisp: Add new QUERY method for SQL-OBJECT-QUERY. Move
        from basic/basic-sql.lisp the DO-QUERY and MAP-QUERY since they now
        depend on sql-object-query-type.
        * sql/loop-extensions.lisp: Move from base package
        * classic/package.lisp: remove references to map-query and do-query

4 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * TODO: New section on optimizations, especially optimizing JOINs.
        * sql/objects.lisp: Have :target-slot return of list of lists rather
        than a list of cons pairs to be conformant with CommonSQL.
        Make :target-slot much more efficient by using a SQL inner join
        statement and just requiring one SQL query. Add :retrieval :deferrred
        to target-slot joins. Add placeholder for update-objects-join.
        * sql/classes.lisp: Add :inner-join and :on slots to sql-query class
        and process them for query output-sql. 

4 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * Version 2.10.11
        * base/basic-sql.lisp: Avoid multiple evaluation
        of query-expression in DO-QUERY
        * sql/objects.lisp: Make SELECT a normal function.
        SELECT now accepts type-modified database identifiers, such as
        [foo :string] which means that the values in column foo are returned 
        as Lisp strings. Add new *update-records-on-make-instance* special
        variable controlling automatic creation of new instances. Add missing
        RESULT-TYPES keyword to FIND-ALL. Add :target-slot support.
        * sql/packages.lisp: Export *update-records-on-make-instance* 
        * test/test-oodml.lisp: Add tests for :target-slot and many-to-many
        selections.
        * test/test-fdml.lisp: Add tests for type-modified
        database identifiers.
        * test/test-init.lisp: Stop using add-relation since implementing
        many-to-many joins. Use *update-records-on-make-instance* 
        to automatically store records on instance creation. Add many-to-many
        employee-address view-class.
        
4 May 2004 Kevin Rosenberg (kevin@rosenberg.net)
        * Version 2.10.10
        * base/loop.lisp: Add object iteration. Use :result-type
        :auto for result-set. Remove 
        duplicate (and non-correct) code for non-list variables by
        simply making an atom variable into a list. 
        * sql/package.lisp: Remove unnecessary clsql-sys package
        and replace it with clsql.
        * sql/metaclasses.lisp: Properly store specified-type from
        direct-slot-definition and then store translated type in
        effective-slot-definition
        * sql/classes.lisp: Don't output type in sql-output
        for SQL-IDENT-ATTRIBUTE. This is in preparation for supporting
        [foo :integer] as fields in SELECT.
        * sql/query.lisp: Set default for :result-types to :auto in
        FDML QUERY.
        * sql/objects.lisp: Use specified-type when invocating 
        database-get-type-specifier. def-view-class macro now returns
        the class instance.
        * base/basic-sql.lisp: Make :AUTO the default value for
        :RESULT-TYPES for MAP-QUERY and DO-QUERY.

        * mysql/mysql-sql.lisp:
        - Added support for Allegro CL and Lispworks using UFFI layer
        - Changed database-connect to use mysql-real-connect. This way,
          can avoid using double (unwind-protect)
        - Changed database-connect to have MySQL library allocate space
          for MYSQL structure. This will make the code more robust in
          the event that MySQL library changes the size of the mysql-mysql
          structure.
