Release Notes TOY System Version 2.3.1
======================================

 FIXED BUGS


- The Linux version did not work. Now, it has been fixed and tested on
Ubuntu 6.10, Kubuntu 7.04 (Feisty), and Mandriva Linux 2007 Spring.

- Bridge unification did not exactly follow theory. Now, it infers
from two bridges with the same variable at an end, the binding of the
variables at the other ends. The following example illustrates this
point.

With version 2.3.0:

        Toy(R+FD)> X #== RX, Y #== RY, X == Y
              { Y -> X }
              { X #== RX,
                X #== RY }
              Elapsed time: 0 ms.
        sol.1, more solutions (y/n/d/a) [y]?
              no
              Elapsed time: 0 ms.

and with the current version:

        Toy(R+FD)> X #== RX, Y #== RY, X == Y
              { Y -> X,
                RY -> RX }
              { X #== RX }
              Elapsed time: 0 ms.
        sol.1, more solutions (y/n/d/a) [y]?
              no
              Elapsed time: 0 ms.


- It was possible to enable projection when finite domain and/or real
constraint libraries were unloaded.

- Missing answers involved in reification when projection was
enabled. In particular, the modified built-ins are: #>, #<, #>=, #<=,
<, > <==, and >=.
