An excerpt from the readme of the new Fruit:

 "added PV-node extensions (this is from Toga), e.g. extending
  recaptures only at PV nodes.  Not sure if these extensions help; if
  they do, we all need to recognise Thomas Gaksch's contribution to
  the community!"

In my opinion it does not matter whether they help. In my interpretation Fabien
uses something Thomas invented or something from his code. The same what Thomas
did (only to much less extent).
This adds to the confusion and controversion. What do we have now: two engines
or two personalities? Or more? Fruit 2.1 based on Toga II based on Fruit 2.0?
Ridiculous. The whole GPL is ridiculous.
Maybe Fabien intended to implement these PV-node extensions anyway. Thomas did
it _for him_ (!) and now Fabien has to refer to Thomas otherwise he would be a

I can only recommend to all authors not to publish their source code. At least
not if their engine plays too well. Maybe it is too late.
