The stable release of Ubuntu 13.04 became available for download today, with Canonical promising performance and graphical improvements to help prepare the operating system for convergence across PCs, phones, and tablets.
“Performance on lightweight systems was a core focus for this cycle, as a prelude to Ubuntu’s release on a range of mobile form factors,” Canonical said in an announcement today. “As a result 13.04 delivers significantly faster response times in casual use, and a reduced memory footprint that benefits all users.”
Named “Raring Ringtail,”—the prelude to Saucy Salamander—Ubuntu 13.04 is the midway point in the OS’s two-year development cycle. Ubuntu 12.04, the more stable, Long Term Support edition that is supported for five years, was released one year ago. Security updates are only promised for 9 months for interim releases like 13.04. Support windows for interim releases were recently cut from 18 months to 9 months to reduce the number of versions Ubuntu developers must support and let them focus on bigger and better things.
