Barry Kauler, the developer of the Puppy family of Linux distributions, has released version 5.5 of the Wary and Racy branches of the project. Wary is the edition of Puppy designed to be run on older hardware, whereas Racy has more features and needs more system resources but is based on Wary. For version 5.5, both editions had most of their underlying system libraries and some of the applications updated during the development phase; this took almost a year from the release of Wary 5.3 in April 2012.
Kauler has also released version 5.4.91 of Quirky, the experimental branch of Puppy that is used as a testbed for new ideas that might later be incorporated into the other editions.
