Oh, sorry Greg. There must be something that I haven't understand about the
development process... :(
Obviously I agree that there is no rush here :)
As I said, this morning I read git log and saw patches that seemed more
recent; thus I thought that was the case to ask. I just (wrongly) thought
that the v3 of the patch got unnoticed or dropped because of some requests
that I had missed.
Thanks for the explanation,
