Codenamed "Cosmic Cuttlefish", 18.10 continues Ubuntu's proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing new features and fixing bugs. The Ubuntu kernel has been updated to the 4.18 based Linux kernel, our default toolchain has moved to gcc 8.2 with glibc 2.28, and we've also updated to openssl 1.1.1 and gnutls 3.6.4 with TLS1.3 support. Ubuntu Desktop 18.04 LTS brings a fresh look with the community-driven Yaru theme replacing our long-serving Ambiance and Radiance themes. We are shipping the latest GNOME 3.30, Firefox 63, LibreOffice 6.1.2, and many others. Ubuntu Server 18.10 includes the Rocky release of OpenStack including the clustering enabled LXD 3.0, new network configuration via netplan.io, and iteration on the next-generation fast server installer. Ubuntu Server brings major updates to industry standard packages available on private clouds, public clouds, containers or bare metal in your datacentre. The newest Ubuntu Budgie, Kubuntu, Lubuntu, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu are also being released today.
