Today, April 23, official Ubuntu 20.04 LTS ISO images have been made available publicly and can be downloaded from releases.ubuntu.com.
Ubuntu 20.04 LTS for desktops comes with GNOME 3.36, the Linux 5.4 LTS kernel, and many enhancements that support WireGuard VPN.
WireGuard® is a new, simplified VPN with modern cryptography defaults. WireGuard is included in Ubuntu 20.04 LTS and will be backported to Ubuntu 18.04 LTS to support widespread enterprise adoption. “Including WireGuard by default in all recent versions of Ubuntu means that users will finally have a great out-of-the-box secure tunnel on Ubuntu,” said Jason A. Donenfeld, creator of WireGuard.
Many other package updates have also been made, such as: glibc 2.31, Mesa 20.0, PulseAudio 14.0, OpenJDK 11, GCC 9.3, python 3.8.2, php 7.4, Firefox 74, LibreOffice 6.4. In addition to all this, the "GameMode" package was added to the system.
GameMode is the daemon/lib combination created by Feral Interactive for Linux that allows games to temporarily request a set of optimizations for the host operating system and/or game process.
Ubuntu 20.04 LTS also includes Secure Boot to protect against low level attacks and rootkits, often employed by Advanced Persistent Threat groups, and limits attack proliferation or ‘blast radius’ with strict snap confinement of key exposed applications on the desktop and server such as the local Kubernetes package MicroK8s. To mitigate social engineering attacks, Ubuntu 20.04 LTS introduces Fast ID Online (FIDO) for universal multi-factor and passwordless authentication.
PointRelease Ubuntu 20.04.1 will be available on July 23.
