Welcome, fellow Linux enthusiasts! We’re here today to talk about something truly exciting that’s been making waves in the open-source community: the brand-new Fedora 43. I’ve had the pleasure of exploring the beta version and playing with it extensively, and I can tell you that this release feels incredibly polished and well-thought-out.
This new version comes absolutely packed with stunning updates that will likely redefine your Linux desktop experience. From the sleek new GNOME 49 to a host of under-the-hood performance boosts, there’s a lot to unpack. In this detailed article, we’ll dive into every major change, from new default apps and installer improvements to kernel upgrades and security enhancements.
So, grab a cup of coffee, and let’s get into it!

A Glimpse into the Future: The New GNOME 49
One of the most significant updates in Fedora 43 is the integration of the all-new GNOME 49. This is a monumental release for the GNOME desktop environment, bringing a fresh set of default applications, subtle but impactful UI refinements, and some major architectural decisions.
Originally, the GNOME developers had planned for GNOME 49 to be a Wayland-only environment, completely removing the traditional X11 session to create a more streamlined experience. However, in a surprising turn of events, the final GNOME 49 release re-enabled X11 sessions. Fedora 43, however, has stuck to its original plan and has completely removed the X11 session. This means that Fedora 43 is now a fully Wayland-native distribution, offering a more modern and cohesive desktop experience.
Now, some of you might be wondering about application compatibility. It’s a valid concern since many popular Linux applications still rely on X11. But don’t worry! These applications will continue to work flawlessly on Wayland using XWayland, a compatibility layer that allows X11 apps to run on a Wayland display server. Additionally, while Intel and AMD graphics have had excellent Wayland support for a while, NVIDIA has also significantly improved its drivers, making the Wayland experience on NVIDIA hardware surprisingly smooth.
So far, we’ve talked about the technical side of things. Now let’s move on to the more visible and exciting part—the new apps!
A Fresh Lineup of Default Apps
GNOME 49 is swapping out several of its long-standing default applications for a more modern and well-rounded lineup. This is a huge step toward creating a more contemporary desktop environment. Let’s take a closer look at the new additions:
- Lupe: This new image viewer replaces the old “Eye of GNOME.” Lupe is a powerful viewer built with Rust, which offers incredible speed and efficiency. Its key feature is GPU acceleration, which makes viewing and navigating through high-resolution images a breeze.
- Showtime: This new video player replaces the old “Totem” player. I have to say, this is a beautiful upgrade. Showtime has a modern, borderless window design that looks fantastic, providing a more immersive viewing experience.
- Papers: This is a brand new document viewer that replaces the old “Evince.” Papers is a clean, minimalist application designed for a distraction-free reading experience.
- Manuals: This new application replaces the old “Devhelp” tool. It’s a turbocharged replacement that uses an SQLite database for lightning-fast searches. It allows you to quickly find documentation across your system and in Flatpaks, which is a huge time-saver for developers and power users.
Beyond the new apps, GNOME 49 also brings a ton of quality-of-life improvements. The lock screen has been given a major upgrade, now featuring media playback controls so you can manage your music without having to unlock your session. Application permissions have been fine-tuned for better security, and the file manager‘s search functionality has been tweaked for better performance. All in all, these changes work together to deliver a polished and refreshed desktop experience in the new Fedora release.
KDE Plasma Edition: Polished and Professional
Fedora’s KDE Plasma Edition has also received a significant update, moving to the brand-new KDE Plasma 6.4. This release is all about polishing the user experience and adding powerful new features for both everyday users and creative professionals.
An Enhanced Screenshot and Recording Experience
One of the most notable changes is the major user interface redesign for Spectacle, the default screenshot and screen recording tool. It has been completely rebuilt to simplify your workflow. Now, when you press the Print Screen button, the tool directly jumps into the rectangular window selection mode, allowing you to capture exactly what you need without a fuss. Annotating and sharing your screenshots and screen recordings have also been made much easier.

HDR Calibration and Enhanced Display Features
For users with HDR screens, Plasma 6.4 introduces the HDR calibration wizard. This is a huge deal for creative professionals and anyone who values color accuracy. The wizard gives you the tools for professional-level screen calibration, helping you get the best possible color and contrast out of your HDR display.
Smart User Experience Enhancements
Plasma 6.4 is packed with small but brilliant improvements that make a big difference in daily use.
- Automatic “Do Not Disturb” Mode: When any application goes full-screen (for example, when you’re gaming or giving a presentation), the system automatically enters a “do not disturb” mode. This means no more pop-up notifications disrupting your focus, which is a feature I’m surprised hasn’t been a default everywhere until now.
- New App Tags: The application menu now adds a neat little “New” tag next to newly installed apps, making it easy to spot what’s fresh on your system.
- KRunner Improvements: KRunner, the “do everything” launcher, has been improved to show visual previews of color codes. This is a fantastic touch for designers and developers who work with color palettes.
- Subtle Theming Changes: The default “Breeze” theme has been subtly darkened, and the desktop background now darkens when an authentication prompt appears, helping you focus on the task at hand and improving security.
- X11 Session: While the main Fedora Workstation has dropped X11 completely, KDE developers are still keeping it as an option. However, it is not pre-installed and must be installed manually if you want to use it. This gives users the flexibility to choose, which is a core tenet of the Linux community.
Under the Hood: The Linux Kernel 6.17 and RPM 6.0
Fedora 43 isn’t just about a pretty new interface; it’s also packed with powerful under-the-hood upgrades that enhance performance and security. Let’s take a look at the two biggest changes.
Linux Kernel 6.17
Fedora 43 is powered by the brand-new Linux kernel 6.17. This update brings a wave of improvements across the board, including:
- Performance Optimizations: The new kernel brings performance enhancements that improve throughput and reduce latency for file operations, making the entire system feel snappier.
- Improved Hardware Support: It comes with updated drivers for the latest CPUs, GPUs, and other hardware. This includes initial drivers for Intel’s upcoming Wildcat Lake processors and enabled drivers for Intel Xeon 3 graphics. For AMD users, the Hardware Feedback Interface (HFI) has been merged, which helps improve performance on CPUs with heterogeneous cores.
- BTRFS Performance Boost: Since BTRFS is Fedora’s default file system, this is a big deal. The new kernel delivers significant performance improvements for BTRFS, making file operations faster and more efficient.
- Security: The new kernel includes a critical security framework called Attack Vector Controls. This is designed to mitigate major CPU vulnerabilities like Spectre and Meltdown, which provides an extra layer of protection for your system.
RPM 6.0: A New Era of Package Management
Another huge update in Fedora 43 is the shift to RPM 6.0, which is the core package management system’s first major version bump in years.
- Enforced PGP Signature Checking: The most important change in RPM 6.0 is the enforcement of PGP signature checking by default for all package operations. This means that every single package you install is cryptographically verified, which dramatically reduces the risk of installing a tampered or malicious package. This is a huge step forward for security and ensures the integrity of the software ecosystem.
- Enhanced Security: RPM 6.0 enhances OpenPGP integration and supports multiple cryptographic signatures per package, strengthening the verification process for developers and system administrators.
- Streamlined Workflows: The update also includes enhanced debugging features, making it easier to diagnose and resolve packaging issues. These improvements, combined with the security enhancements, make RPM 6.0 a foundational upgrade that quietly but significantly strengthens Fedora’s entire software ecosystem.
Zstandard Compression and Faster Boot Times
Fedora 43 is now using Zstandard compression for the initial RAM disk (initramfs). To put it simply, this means your computer will boot up slightly faster and use less memory right from the start.
By using the modern and incredibly fast Zstandard algorithm to compress the files needed during boot, your system can load everything it needs more quickly. While this change might not be as noticeable on modern systems with fast SSDs, it will make a significant difference on older hardware, giving you a snappier startup experience every time you turn on your machine.
The Anaconda Web UI Installer Gets Even Better
In the last version of Fedora, we got a glimpse of the new Anaconda Web UI installer, which I’m personally a huge fan of. In Fedora 43, it’s gotten even better.
- Default for All Spins: The Anaconda Web UI installer is now the default for all Fedora spins, whether you’re installing the KDE Plasma desktop, XFCE, or any other flavor. This provides a consistent, polished, and user-friendly installation experience across the board.
- DNF5 Integration: The installer now uses DNF5 for all package installations, which is an upgrade from the previous DNF4. DNF5 is faster and more efficient, making the entire installation process feel quicker and more streamlined.
- GPT Partition Table: For modern systems, the installer now enforces the use of the GPT partition table for all UEFI-based installations. It has removed support for the old MBR partition discs in UEFI mode, which is a move toward a more modern and stable standard.
- Enhanced Security: The entire installation process also benefits from the system-wide upgrade to RPM 6.0, which means you get stronger security right from the start, with enforced PGP signature checking even before you boot into your new desktop.
Fedora has really hit a home run with this web UI installer. The process is so simple, linear, and concise that it feels like a three-step process, which is a breath of fresh air compared to other installers.
A Stunning New Look: Wallpapers and Visuals
When you first boot up Fedora 43, you’re greeted with a stunning new default wallpaper. This one is an absolute stunner, honoring the late astronaut Sally Ride and giving the desktop a fantastic, modern look. In addition, the GNOME team has also curated a set of new wallpapers that are pretty cool.
Beyond the visuals, there’s a technical change to note as well. Fedora 43 is switching the format of all default background images from PNG to JPEG XL. This new format drastically cuts down on file sizes while preserving visual quality. Furthermore, the GNOME compositor Mutter has been updated to support 10-bit, 12-bit, and 16-bit wallpapers, which allows for richer, more accurate, and more vibrant colors, especially as we move into the world of HDR wallpapers.
What Else is New?
Fedora 43 also brings a fresh set of new packages, delivering the latest and greatest from software libraries and toolchains. Here’s a quick rundown of some of the major updates:
- GCC 15.2, LLVM 21: These are major compiler updates that bring better performance and new features for developers.
- Python 3.14: The latest version of Python is included, with all the new language features and performance improvements.
- Java 25: A new OpenJDK 25 package has been introduced, as Fedora moves away from the concept of a single system JDK, offering more flexibility for developers.
- System Housekeeping: To keep the system lean and contemporary, several unmaintained and obsolete packages have been retired, including the old GTK Rust bindings.
