The new edition of Fedora 33 has already been released and comes with quite a few important changes, of which many of them were made known during the development of this new version and among them the transition to Btrfs, change from vi to nano, Earlyoom enabled by default, among other things more.
It seems that Fedora 33 is a fairly innovative version, as a large number of changes have been introduced and some quite important and above all many of Fedora's followers are already interested in knowing the improvements introduced.
Fedora 33 Key New Features
Among the new features that are presented in this new version of Fedora 33 we can find the following changes in all desktop variants.
Change Ext4 to BTRFS as the default file system
Using the built-in Btrfs partition manager will solve the problems with the exhaustion of free disk space when the / and / home directories are mounted separately.
With Btrfs, these partitions can be placed in two subsections, mounted separately, but using the same disk space. Btrfs will also allow features such as snapshots, transparent data compression, proper I / O isolation via cgroups2, and partition resizing on the fly.
Bye I saw, hello Nano
Another change that stands out is changing the vi editor, for the nano text editor. The change is due to the desire to make the layout more accessible to beginners by providing an editor that can be used by any user who does not have a special knowledge of the working methods in the Vi editor.
Using zRam
On the other hand, we may also find that zRAM is now used instead of the traditional swap partition.
And this is because zRAM is a RAM unit that uses compressionTherefore it will use much less memory like its swap counterpart.
Thanks to compression, the zRAM driver will allocate memory at approximately half the page-out rate offered by a traditional swap partition. That equates to a significant performance boost when a system runs out of RAM.
Version Desktop, Server and IoT go hand in hand
Version for Internet of things (Fedora IoT) has been adopted in the number of official editions, which now comes bundled with Fedora Workstation and Fedora Server.
Fedora IoT Edition is based on the same technologies used in Fedora CoreOS, Fedora Atomic Host, and Fedora Silverblue and offers a simplified system environment that is atomically upgraded by replacing the entire system image, without breaking into separate packages.
To control integrity, the entire system image is certified with a digital signature. To separate the applications from the main system, it is proposed to use isolated containers (podman is used for management).
Decoding using VA-API in Wayland and X11
Firefox on Fedora 33 already has support activated for hardware acceleration for decoding video using VA-API (Video Acceleration API) and FFmpegDataDecoder, which is included including sessions based on the WebRTC technology used in web applications for video conferencing.
The acceleration works in Wayland and X11-based environments when you run the option »MOZ_X11_EGL = 1 firefox" and the setting "media.ffmpeg.vaapi.enabled" is enabled.
Other Important Changes in Fedora 33
Of the other changes that we can find in Fedora 33 in the main version, Gnome 3.38 is included, the latest version of the desktop environment now includes a tour after installation to help users explore its features. It also improves screen recording and multi-screen support.
Besides that for developers and advanced users, Boxes now allows to edit the XML libvirt virtual machines (VMs) directly, allowing them to change advanced settings that are not available in the user interface.
In the edition of Fedora 33 KDE, Earlyoom Background Process Now Available enabled by default, which was introduced in the latest version of Fedora Workstation.
