Ubuntu 18.04.4 LTS released Wednesday—here’s what’s new

This Wednesday, the current Ubuntu LTS (Long Term Service) release—Bionic Beaver—launched its fourth maintenance update.
Ubuntu is one of the most predictable operating system distributions in terms of its release cycle—a new version is launched in April and October of each year. Most of these are interim releases, supported for a single year from launch; but the April release of each even-numbered year is an LTS, supported for five years. LTS releases also get maintenance releases as necessary, typically about every three to six months during the support cycle of the LTS.
Today’s release, 18.04.4, is one of those maintenance releases. It’s not as shiny and exciting as entirely new versions, of course, but it does pack in some worthwhile security and bugfix

Linus Torvalds pulled WireGuard VPN into the 5.6 kernel source tree

Enlarge / It’s not likely to be an accident that “add WireGuard” is number one on this list. (credit: Jim Salter)
Yesterday, Linux creator Linus Torvalds merged David Miller’s net-next into his source tree for the Linux 5.6 kernel. This merger added plenty of new network-related drivers and features to the upcoming 5.6 kernel, with No.1 on the list being simply “Add WireGuard.”
As previously reported, WireGuard was pulled into net-next in December—so its inclusion into Linus’ 5.6 source tree isn’t exactly a surprise. It does represent clearing another potential hurdle for the project; there is undoubtedly more refinement work to be done before the kernel is finalized, but with Linus having pulled it in-tree, the likelihood that it will disappear between now and 5.6’s final release (expected sometime in May or early June) is vanishingly small.
WireGuard’s Jason Donenfeld is also contributing AVX crypto optimizations to the kernel outside the WireGuard
