The ROSA company is happy to present the long waited ROSA Desktop Fresh R4, the number 4 in the "R" lineup of the free ROSA distros with the KDE desktop as a main graphical environment. The distro presents a vast collection of games and emulators and the Steam platform package along with standard suite of audio and video communications software including the newest version of Skype. All modern video formats are supported. The distribution includes the fresh LibreOffice v4.3.1, the full TeX suite for true nerds as well along with best Linux desktop publishing, text editing and polygraphy WYSISYG software. The LAMP/C++/… enviroment packages are waiting to be installed by true hackers.

The R4 distribution is recommended for both the home users who want to communicate and surf the web and for the experienced ones who'd like to tweak the system their own way. ROSA Fresh R4 is based on a new rosa2014.1 platform which will be supported for 2 years and will serve as a base for several future releases.

Unlike R1, R2 and R3 releases, this release uses different repositories based on a new rosa2014.1 platform. All users of previous ROSA Desktop Fresh releases are highly encouraged to migrate to R4 release, since old releases are no longer supported. We recommend to install R4 over existing system from ISO image (if you have a separate /home partition, you can reuse it to save all your data), but it is also possible to update existing systems without re-installation.
