Regarding the change of the compatible string for the replicator, can you confirm that nothing ever used the old string? In doubt, it might be better to keep both strings present for backward-compatibility. Arnd

So, as such the compatible string is not used by the drivers and Rob suggested to remove the old one. Cheers Suzuki
