[Retros] New version of Natch

[Pascal Wassong]

Hello,

a new version of Natch is available: 3.2.  This version corrects 2 bugs:

- Natch could do anything, for example crash or not find the solution,
  when there were only kings and pawns in the diagram to reach.

- a very complicaded situation, where all following features are needed
  to trigger it:

  - a piece in captured on its home square without moving.
  - the piece who captures makes a switchback on this square, to
    let pass another piece.
  - the piece who captures is then captured on this square by a
    piece which makes no more moves.

An example of such a game is: 1.Nf3 c5 2.Ne5 Qa5 3.Nxd7 b6 4.Ne5 Bh3
5.Nd7 Nxd7

The new version is available at the usual place: http://Natch.free.fr

Best wishes,
Pascal
