Puppy 1 series will run comfortably on very dated hardware, such as a Pentium computer with at least 32 MB RAM. For newer systems, the USB keydrive version might be better (although if USB device booting is not directly supported in the BIOS, the Puppy floppy boot disk can be used to kick-start it). It is possible to run Puppy Linux with Windows 9x/Windows Me. It is also possible, if the BIOS does not support booting from USB drive, to boot from the CD and keep user state on a USB keydrive; this will be saved on shutdown and read from the USB device on bootup.
Puppy 2 uses the Mozilla-based SeaMonkey as its Internet suite (primarily a web browser and e-mail client).
Puppy 3 features Slackware 12 compatibility. This is accomplished by the inclusion of almost all the dependencies needed for the installation of Slackware packages. However, Puppy Linux is not a Slackware-based distribution.
Puppy 4 is built from scratch using the T2 SDE and no longer features native Slackware 12 compatibility in order to reduce the size and include newer package versions than that found in 3. To compensate for this, an optional "compatibility collection" of packages was created that restores some of the lost compatibility.
- Puppy 4.2 features changes to the user interface and backend, upgraded packages, language and character support, new in-house software and optimizations, while still keeping the ISO image size under 100 MB.
Puppy 5 is based on a project called Woof which is designed to assemble a Puppy Linux distribution from the packages of other Linux distributions. Woof includes some binaries and software derived from Ubuntu, Debian, Slackware, T2 SDE, or Arch repositories. Puppy 5 came with a stripped down version of the Midori browser to be used for reading help files and a choice of web browsers to be installed, including Chromium, Firefox, SeaMonkey Internet Suite, Iron and Opera.

Famous quotes containing the words release and/or history:
“An inquiry about the attitude towards the release of so-called political prisoners. I should be very sorry to see the United States holding anyone in confinement on account of any opinion that that person might hold. It is a fundamental tenet of our institutions that people have a right to believe what they want to believe and hold such opinions as they want to hold without having to answer to anyone for their private opinion.”
—Calvin Coolidge (1872–1933)
“The history of philosophy is to a great extent that of a certain clash of human temperaments.”
—William James (1842–1910)
