A few hours ago we learned about the new version of Puppy Linux, a version called Quirky Werewolf as it is based on Ubuntu's Wily Werewolf. Puppy Linux is geared towards computers with few resources and in this case it is not an exception, so we will not have very heavy applications like Chromium but something light like Seamonkey.
The official Quirky Werewolf repositories are based on Ubuntu 15.10 so it inherits the bad and the good as the latest stable kernel, Kernel 4.2.
In the case of the Live-cd version, a great tool for almost obsolete computers, it has an improved and accelerated system startup as well as the inclusion of zram to improve the use and management of ram memory in computers.
An improved file system has also been used that will allow us not only to use persistence but also to recognize disk space efficiently. The UEFI support It is also higher in this version, although in versions of the Puppy Linux 6.x branch they already had this compatibility.
As always, Quirky Werewolf is distributed in a disk image to install and use on a cd-rom or on a usb, however there are already methods to completely install the system on the computer's hard disk and be able to enjoy Puppy Linux without having to use the cd-rom drive of our computer or the usb.
I personally like Puppy Linux for older computers, but in this case I have to say that I don't think Quirky Werewolf is as light as they say. Surely it will be light, but the system itself is somewhat heavy for some computers with some years, so Puppy Linux 7.3 will not be an exception or at least I think so.
Even so if you want to try it, in this link You can find all the information about Quirky Werewolf as well as the download links. Remember that it is not necessary to always have it in a usb.
