Linux 4.0 Goes Live With Live Kernel Patching

Linux creator Linus Torvalds officially released the Linux 4.0 kernel on April 12, marking the first major number change for Linux since Linux 3.0 debuted in 2011. Although a change in numbers can often signify a major software change, in Linux development the major version numbers are more of an arbitrary decision. Linux 4.0 does, however, include a number of new innovative capabilities, including a live kernel patching capability that could help further advance server high availability.
