The big server news of the day is the availability of Ubuntu 18.04 LTS codenamed Bionic Beaver. In the industry, this is major news because Ubuntu long-term support (LTS) releases happen only once every two years. The last one was Ubuntu 16.04 LTS in April 2016 which brought features like significantly improved ARMv8 support and ZFS to Ubuntu. With each LTS version, many software ecosystems will adopt the LTS version to ensure they have a stable running platform for years. For example, Canonical (the company behind Ubuntu) will support Ubuntu 18.04 LTS until 2023.
