Hi All

You can download it here:

PLEASE TRY this archives to find if any glitches present.


----------------------------------------------------------
** This 3.1 release is MAJOR improvement of VLINK feature. **

[NEW] Added new commands to do REFACTORING of database structure

    API:

        VLink2.CopyLinksTo()
        VLink2.CopyLinksFrom()

    SQL:

        COPY LINKS FROM ...

    This commands are so universal, flexible and powerful,
    that you can convert even Relational case of M:M link based
    on third table into BianryLink M:M

    You can read and see pictures of different refactoring cases
    step by step here:

----------------------------------------------------------
[NEW] Now BinaryLink of 1:M, M:1 and 1:1 power has OPTIMIZED storage,
    which is NOT worse of ObjectPtr by all parameters,
    and by some benches wins ObjectPtr about 5-6 times!
                                                           ^^^^^^^^^

This fact means that starting from 3.1 we can RECOMMEND always
to use BinaryLink for all kinds of link between 2 tables.
