looking  at Object Arts | Exciting News for Dolphin Users we read:

Object Arts announces a collaboration with Lesser Software to produce the next generation of Dolphin Smalltalk.

We hope Dolphin Smalltalk will not die: we have that fear  in September 2007 reading a press release called “A Brighter Future for Dolphin?“.

ObjectsArts was asking money to get Dolphin open source. A rather bad move, in our own opinion, and in fact no thing happen. Now it seems Doplphin will be included in a bigger project. Good luck, big fish!
