Fedora 22 正式发布并提供下载了，此版本中 Fedora KDE spin 默认的工作区域是 Plasma 5。重要亮点如下：
Updated Docker Images – The Fedora 22 release includes updated Docker images that you can use as the base of your containerized applications.
Vagrant Boxes – One of the oft-requested features for Fedora is an “official” Vagrant box that developers can use to spin up images using the popular Vagrant tool for building development environments. With the Fedora 22 release we now offer Vagrant Boxes for libvirt and VirtualBox, so developers on Linux, Mac OS X, and Windows can spin up Fedora-based development environments with ease. Users can choose a Vagrant box for Fedora 22 Atomic Host and Fedora 22 Cloud base edition.
Atomic Improvements – Fedora 22 Atomic Host includes a number of interesting improvements, including the Atomic command, updated Docker, Kubernetes, Flannel, and rpm-ostree packages.
Dockerfiles – Fedora 22 also includes a fedora-dockerfiles package (and up-to-date git repository) for building applications with the base Fedora 22 Dockerfile and additional packages.
Database Server Role. The Fedora Server edition focuses on easy of different server roles. Fedora 21 debuted with an Domain Controller Role featuring FreeIPA. For this release, we’ve added a Database Server role, built around PostgreSQL.
Default to XFS filesystem. The default file system type for Fedora Server installs will be XFS running atop LVM for all partitions except /boot. The /boot partition will remain a non-LVM, ext4 partition due to technological limitations of the bootloader.
Cockpit will be compatible between OS releases. Cockpit is a server manager that makes it easy to administer your GNU/Linux servers via a web browser.
Easy to use. Cockpit is perfect for new sysadmins, allowing them to easily perform simple tasks such as storage administration, inspecting journals and starting and stopping services.
No interference. Jumping between the terminal and the web tool is no problem. A service started via Cockpit can be stopped via the terminal. Likewise, if an error occurs in the terminal, it can be seen in the Cockpit journal interface.
Multi-server. You can monitor and administer several servers at the same time.
Better notifications. Thanks both to work done in GNOME 3.16 and other projects like the Automatic Bug Reporting Tool (ABRT), notifications keep you better informed, but interfere less with your work. They now appear anchored to the center of the top bar, and no longer cover up the bottom of the screen where you are often reading a terminal or browser. An unobtrusive marker appears in the calendar to let you know you have unread notifications. If ABRT detects a serious bug, a friendly notification appears and allows you to report the bug information, but doesn’t overload you with details. And if you’re a serious Terminal user, longer background jobs now notify you when they’re done, so you can get on with other work and pick up the results when you’re ready.
Refined themes. The GNOME Shell and other themes and design are refined and improved. Now you can more easily identify information on the screen, adjust window size and placement, and navigate your files and folders. Improved bridging between desktop environment themes allows apps from other environments like KDE to look and feel more like native apps as they’re updated to take advantage of this feature. Standard scrollbars have been replaced by a minimal, overlaid indicator, while a scrollbar trough is shown when needed. This create a cleaner, less distracting view which helps you focus on window content. These “overlay scrollbars” are also better suited to mouse scroll wheels and touchpad scrolling.
Software. The Software app has more and better data than ever before, and makes it easy for you to find a wide variety of useful free software. It also makes keeping your system up to date a snap. The Software app also can install all sorts of extras such as fonts or media helpers.
Files. The updated layout in Files gives a better view of your files and folders, and a new view popover makes it easy to change the zoom level and sort order from a single place. You can also now move files and folders to the trash intuitively using the Delete key, rather than the Ctrl+Delete keyboard combination.
Image Viewer. The Image Viewer has been redesigned to reduce the amount of window chrome and give more space to images.
Boxes. The user interface for Boxes, the application for virtual and remote machines, has a large number of improvements, including new preferences dialogs, a revamped box creation assistant, a feature to send keyboard shortcuts to a box, and display scaling by default.
Vagrant. Developers will appreciate the addition of software development environment software Vagrant into Fedora — it’ll work using our included virtualization technology, with no need to install third-party virtualization (like VirtualBox). Use this to work on top of the Cloud images mentioned above, or launch your own Vagrant boxes.
