The fact that Russia's ROSA Labs once collaborated with Mandriva is evident in the company's latest release, ROSA Desktop 2012. Nevertheless, since breaking from Mandriva, ROSA Labs has forked the distro onto its own unique development path. ROSA Desktop 2012 is an LSB-compliant distro that features a customized KDE desktop. The free edition sports only free software; the Extended Edition includes nonfree components and proprietary software, such as codecs. ROSA Labs says that by developing ROSA Desktop 2012 with its own software development and build environment—ROSA ABF—the company is able to achieve unmatched technological independence, high quality and up to five years of technical support. Examples of new features include EFI/UEFI support, improved hardware detection and improved compatibility with Windows 8. Supported languages include English, French, German, Italian, Portuguese, Romanian, Russian, Spanish and Ukrainian.
