Puppy 4.1 marks the last release of Puppy with Mr. Kauler in sole responsiility for the entire Puppy operation, as has been the case since the original release of Puppy. This has been an enormous accomplishment by Barry, when one considers that he not only created a unique and innovative operating system, but also the entire Puppy community. He did not do this alone, of course, and Kauler is the first to say that and to thank eveyone who has helped, but it was all created because he saw the kind of operating system he wanted and then went about building it.
