No yet, my Oasis reader is still supported. This is probably really useful for the older Kindles that have just been cut off from Amazon.

I tried it on my Kobo reader and I think I just did a post about that 2 or 3 days ago. Was really very impressed with it and it loads alongside the Kobo software so I did not have to wipe the original software. Packed full of reading stats and some powerful plugisn as well.
