Welcome to the Raring Ringtail edition of Kubuntu, an open source operating system suitable for home and small offices, designed as a replacement for the Ubuntu Linux distribution on which it is based. It uses the KDE Plasma Workspaces and Applications project as its default desktop environment.
Now available for the PowerPC architecture
Kubuntu 13.04 was officially announced by Canonical on April 25, 2013 and supported until January 27, 2014. Some strange modifications took place in this edition, as the 64-bit Mac architecture has been dropped and replaced with the PowerPC one, in addition to the regular 64-bit (amd64), 32-bit (i386) and ARM Hard Float/OMAP4 hardware platforms.
It's still available for download as Live DVD ISO images, but the boot loader has been changed and it now automatically starts the live environment if the user presses no key during the ten second timeout. The hidden boot menu is quite identical with the one found on the Ubuntu edition, allowing the user to start a memory test, check the integrity of the DVD or boot from the first drive.
The next-gen KDE desktop environment has arrived
The welcome screen that allows the user to try or install Kubuntu now runs in full screen, but it offers the same functionality. Furthermore, the next-gen KDE desktop environment has been implemented in this release and it looks astonishing, despite the fact that its layout remains unchanged.
Rekonq is still the default web browser, users can listen to their favorite songs with Amarok, burn CD and DVD images with K3b, chat with their friends and family using KDE IM Contacts, send and receive emails with KMail, download torrents with KTorrent, read the latest news with Akregator, and view movies with Dragon Player.
In conclusion, we can report that Kubuntu 13.04 (Raring Ringtail) is the sole proof that the KDE flavor of Ubuntu has finally reached maturity and provides users with a very stable, familiar, modern, reliable and productive operating system suitable for mid-range and high-end machines. This release is no longer supported and has been archived for historical purposes only.
