We’ve told you that we’re closely monitoring the development cycle of the Ubuntu 17.04 operating system, which was dubbed by Mark Shuttleworth himself as “Zesty Zapus,” and we reported earlier this week that the OS is open for development and the first daily build ISO images are available for download. And now, we’d like to inform our Ubuntu Linux users about the fact that the Ubuntu Kernel Team is currently tracking early Release Candidate versions of the upcoming Linux 4.9 kernel for Ubuntu 17.04 (Zesty Zapus), but, for now, they are waiting for more mature RC builds to land before pushing the new kernel to the repositories.
