After I released Puppy 4.1.2, I "kind of" retired and WhoDo (Warren) took over coordinating 4.2.0 and 4.2.1. WhoDo did a superb job, but he then decided he had enough, so I have stepped back in to coordinate 4.3. There are various reasons why I have taken on this role again, one of them that I have developed a whole new system for building puppies, that I name Woof. This replaces the Unleashed build system. I also designed a new package management system, called the Puppy Package Manager, or just PPM, needed to cope with Woof's ability to build a Puppy from the packages from any distro (Debian, Ubuntu, Arch, Slackware, T2, etc.).

Yes, the Woof build system can build a Puppy from the binary packages from any distro, but in the case of Puppy 4.3 Woof has been used to build "Puppy from Puppy". That is, this is a continuation of the Puppy 4.x series, using the PET packages. To get your mind around this, I highly recommend that you read my introductory web pages on Woof and PPM
