Ubuntu 18.04.3 LTS
The Ubuntu team is pleased to announce the release of Ubuntu 18.04.3 LTS (Long-Term Support) for its Desktop, Server, and Cloud products, as well as other flavours of Ubuntu with long-term support. Like previous LTS series, 18.04.3 includes hardware enablement stacks for use on newer hardware. This support is offered on all architectures and is installed by default when using one of the desktop images.
LTS stands for long-term support — which means five years, until April 2023, of free security and maintenance updates, guaranteed.
Ubuntu Server defaults to installing the GA kernel; however you may select the HWE kernel from the installer bootloader.
As usual, this point release includes many updates, and updated installation media has been provided so that fewer updates will need to be downloaded after installation. These include security updates and corrections for other high-impact bugs, with a focus on maintaining stability and compatibility with Ubuntu 18.04 LTS.
Kubuntu 18.04.3 LTS, Ubuntu Budgie 18.04.3 LTS, Ubuntu MATE 18.04.3 LTS, Lubuntu 18.04.3 LTS, Ubuntu Kylin 18.04.3 LTS, and Xubuntu 18.04.3 LTS are also now available. More details can be found in their individual release notes: https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes#Official_flavours
