Fedora 22 beta recently released, comes with lots of changes, features and bugfixes. A notable change is Yum has been replaced with dnf as the default package manager. Dnf has very similar command line options and configuration files compared to yum but also has several major internal changes including using libsolv in coordination with friends from the openSUSE project for faster and better dependency management.
Fedora 22 beta release notes
- Plasma 5, the successor to KDE Plasma 4, is now the default workspace in the Fedora KDE spin. It has a new theme called Breeze, which has cleaner visuals and better readability, improves certain work-flows and provides overall more consistent and polished interface.
- Changes under the hood include switch to Qt 5 and KDE Frameworks 5 and migration to fully hardware-accelerated graphics stack based on OpenGL(ES).
- The Xfce spin has been updated to Xfce 4.12. This release has an enormous number of improvements, including HiDPI support, improvements to window tiling, support for Gtk3 plugins, and many improvements for multi-monitor support.
- Database Server Role: Fedora 21 introduced Rolekit, a daemon for Linux systems that provides a stable D-Bus interface to manage deployment of server roles. The Fedora 22 release adds onto that work with a database server role based on PostgreSQL.
- Cockpit Updates: The Cockpit Web-based management application has been updated to the latest upstream release which adds many new features as well as a modular design for adding new functionality.
- XFS as default filesystem. XFS scales better for servers and can handle higher storage capacity and we have made it the default filesystem for Fedora 22 server users. Other filesystems including Ext4 will continue to be supported and the ability to choose them have been retained.
