Red Hat sponsored and community-driven open source collaboration OS Fedora delivers new functionality including Linux container deployments, database servers and desktop development, and after extensive work in delivering the first distribution to embrace Fedora.next (Fedora 21), Fedora 22 marks a return to Fedora’s traditional six month release cadence.
As usual the new version is available in cloud, server and workstation versions, with each version including a set of foundational packages, including the Linux kernel, RPM, systemd, and Anaconda. Fedora 22 also introduces an updated package manager for RPM-based Linux distributions: DNF. Fedora Server and Cloud users can expect to see faster results from DNF while retaining command-line interface (CLI) compatibility with Yum for most tasks.
The Fedora 22 Cloud working group has delivered several new features and images designed to help developers and users use Fedora in public and private clouds. The Fedora 22 Atomic Host images now include the Atomic command, a coherent entry point for managing hosts and containers. It also includes several improvements to rpm-ostree, and updated versions of Cockpit, Docker, Kubernetes, and more.
Fedora 22 also offers Vagrant boxes for the base Cloud edition and Atomic Host. An open source technology for quick deployment of software development environments, Vagrant, coupled with libvirt support in Fedora 22's package repository, enables developers to more easily spin up Fedora Vagrant boxes for development and testing, and to share work with other team members.
Finally, the Fedora Project has updated its Docker base image and set of Dockerfiles to help users make use of Fedora 22 in containers.
Fedora 22 Server adds new support for the Database Server Role, based on PostgreSQL. The server edition of Fedora 22 now defaults to the highly-scalable, high-performance XFS file system, which provides quicker crash recovery and also allows for maintenance windows during normal use, limiting downtime.
Several application improvements have also been shipped with Fedora 22 Workstation, including the Software app, which now simplifies the act of finding useful open source software, keeping systems up to date and adding extras, like fonts or media helpers. Files and Boxes (Fedora 22’s virtual and remote machine application) have been enhanced as well, giving a better view of files and folders and a revamped box creation assistant, respectively.
