Ubuntu 12.04 Precise Pangolin is a LTS (long-term support) release and it will ship with Linux kernel 3.2 by default, GNOME 3.2, Unity 5.4.0, LibreOffice 3.5. According to Ubuntu Kernel Release Manager, Leann Ogasawara, as soon as new stable versions of the 3.2 kernel branch will be released, they will be included in Ubuntu. “With Ubuntu 12.04 being an LTS release, our primary focus has been on stability. As such, we chose to ship with a v3.2 based kernel and will continue to rebase to the latest v3.2.y stable kernels as they become available.”
