We already overviewed the new features of Ubuntu Desktop 18.04 LTS, so, in this article, we’ll have a look at what’s new in Ubuntu Server 18.04 LTS. First of all, you should know that this release is powered by the Linux 4.15 kernel series, which includes mitigations for the Meltdown and Spectre security vulnerabilities. The included kernel also provides support for the latest hardware and peripherals from IBM, Intel, and other manufacturers backported from the Linux 4.16 kernel series, support for signing of POWER host and NV kernels, AMD secure memory encryption support, and the latest MD driver with software RAID enhancements.
