Well, that was kind of a matter of perspective. The 2600 compatible was 
added after we'd done the v2 of the binding for the 2400 and 2500 so it 
never needed correcting. But it is a case of "don't use the deprecated 
properties with the 2600 compatible".

I don't think a change is necessary?

Cheers,

Andrew
