Fedora 44 Is Out: GNOME 50, GCC 16, Ruby 4.0, and Wine That Just Works

Fedora 44 dropped on 28 April 2026 after a couple of slip dates, and it's a chunkier release than the version number suggests. Major language toolchain bumps, a kernel that auto-enables NTSYNC for Wine and Steam, GNOME 50, KDE Plasma 6.6, and a switch to DNF5 as the PackageKit backend. Here's what actually matters, what might bite you on upgrade day, and the commands to get from 43 to 44 without surprises.

I've been running it in a Proxmox VM since the beta. The short version: it feels stable, the toolchain refresh is bigger than the headline suggests, and if you write code in Ruby or anything that touches LLVM, you'll want to read the toolchain section before you upgrade your work machine.

Let's go through what's new.

The Headline Versions

Quick rundown of the version bumps you'll notice straight away:

• Linux kernel 6.19.14
• GNOME 50 (Workstation default)
• KDE Plasma 6.6 (with a new Plasma Login Manager)
• GCC 16, with binutils 2.46, glibc 2.43, gdb 16
• LLVM 22 across all sub-projects
• Go 1.26
• Ruby 4.0 (yes, a major version jump from 3.4)
• CMake 4.x with ninja as the new default generator
• MariaDB 11.8 as the default

A lot of those are "ah, fine" upgrades that just keep you current. Two of them - Ruby and CMake - are big enough that they deserve their own sections later.

Wine and Steam Got a Quiet Win

This is the change I think most users will actually feel, even if they don't know what NTSYNC is.

Linux kernel 6.14 introduced NTSYNC, a module that mimics Windows NT thread-synchronisation primitives natively in the kernel. Wine and Proton already had esync and fsync to do similar work, but NTSYNC sticks closer to how Windows actually behaves, which means fewer compatibility quirks and, in some cases, better framerates.

Fedora 44 wires it up so most users never have to think about it. When you install a package that recommends wine-ntsync (Wine itself, or the Steam package from RPM Fusion - both pull wine-ntsync in via RPM Recommends), Fedora drops a config into /usr/lib/modules-load.d/ntsync.conf. After reboot, the module is loaded. No modprobe, no editing config files, no chasing down a forum post.

You can check it's loaded with:

lsmod | grep ntsync

If you see output, you're good. If you don't, install Wine (or Steam from RPM Fusion) and reboot:

# Wine from the main repo
sudo dnf install wine

# Steam usually comes from RPM Fusion (enable it first if you haven't)
sudo dnf install steam

sudo systemctl reboot

Don't expect a 50% framerate jump in everything you run. Proton's existing esync/fsync paths cover most cases. What you will notice is that games which previously needed manual tweaks to work now run out of the box. That's a real quality-of-life win.

GNOME 50: Polish, Not Revolution

GNOME 50 isn't trying to reinvent itself. The big themes are accessibility, colour management, and remote desktop, and most of the visible changes feel like sanding down rough edges rather than throwing furniture around.

The accessibility work matters more than headlines suggest. Screen-reader behaviour is more consistent across apps, keyboard navigation in Settings has fewer dead ends, and the magnifier handles fractional scaling cleanly. If you support users who rely on these tools, the upgrade is a clean win.

Colour management gained proper per-monitor profile support, which is going to make photographers and designers very happy. Remote desktop now negotiates pixel formats more intelligently when you're connecting from a different display profile.

If you're on KDE instead, Plasma 6.6 is the headline. The new Plasma Login Manager replaces SDDM in the default install, and the first-run setup wizard is genuinely shorter than it used to be.

For Developers: The Toolchain Bumps

Here's where you need to pay attention if Fedora is your daily driver for work.

GCC 16 and LLVM 22

GCC 16 brings the usual mix of new C++26 features, better diagnostics, and improved optimisation passes. LLVM 22 ships across clang, lld, lldb, and the rest of the family. If you build native code, neither of these should break anything, but you'll want to rebuild any pre-compiled artifacts that ship with a Fedora 43 toolchain stamp.

Quick sanity check after upgrade:

gcc --version
clang --version

Both should report their new major versions. If you've got a project that pins to an exact GCC version in CI, mirror that in your local Containerfile rather than relying on the system compiler.

Ruby 4.0: The Big Jump

Ruby skipped from 3.4 straight to 4.0 in this cycle. The Fedora project's own change proposal calls it "the superior Ruby development platform" - their words, not mine, but the upgrade itself is the thing to plan for.

Most Ruby code that worked on 3.4 will work on 4.0, but a few rough edges to watch:

• The soname bumped, so some C-extension gems need a rebuild against the new ABI. bundle install should handle this for most gems, but native gems with vendored binaries can stumble.
• A handful of long-deprecated stdlib methods are gone. If your project still has Ruby 1.9-era code lurking, run your test suite before you ship.
• Paths have shifted to fit the new version layout, so anything hard-coding /usr/lib64/ruby/3.4 or similar will need updating.

If you maintain a Rails app, the safest play is:

# In your project directory
rm -rf vendor/bundle
bundle install
bundle exec rspec   # or your test command of choice

Don't blindly dnf upgrade your work machine if you've got a Ruby project with deadlines this week. Spin up a Toolbox container first:

toolbox create --release 44 ruby4-test
toolbox enter ruby4-test
cd ~/projects/my-rails-app
bundle install

That gives you Ruby 4.0 in an isolated environment without touching the rest of your system.

Go 1.26

Quieter upgrade. Most Go code is forward-compatible by design. The standard library has the usual round of additions, and the toolchain is faster on cold builds. Nothing here should bite you.

CMake 4.x with Ninja by Default

This one is small in code but worth flagging. Fedora 44 ships CMake 4.x, and the default generator is now ninja instead of make.

If your build scripts assume make is the generator (looking for Makefile, parsing make output, anything like that), you've got two options:

# Option 1: explicitly request make
cmake -G "Unix Makefiles" .

# Option 2: just use ninja and update your scripts
cmake .
ninja

Ninja is faster, especially on incremental builds, so most projects will benefit from making the switch permanent. But if your CI runs scripts that grep make output, fix them now rather than at 2am next Tuesday.

DNF5 Is the New Backend (For PackageKit Too)

Fedora 41 made DNF5 the default command-line tool. Fedora 44 finishes the job: PackageKit, the abstraction layer that GUI software updaters sit on top of, now uses DNF5 as its backend through libdnf5.

For most users this is invisible. GNOME Software still works, KDE Discover still works, the GUI updater on your aunt's laptop still works. What it means for you, if you're a developer or sysadmin, is that the legacy DNF4 code paths are now genuinely on borrowed time. If you've got internal tooling that shells out to dnf and parses output, this is a good week to make sure you're using the DNF5 syntax.

A few command differences worth noting:

# DNF4-style (still works for backward compatibility, but deprecated)
dnf list installed

# DNF5-style (preferred)
dnf list --installed

Most everyday commands (install, remove, upgrade, search) work identically. The differences are in the more specialised flags - dnf list installed is the classic example, superseded by dnf list --installed in DNF5. Old scripts won't break overnight, but if you're writing new tooling, follow the DNF5 conventions. The manual is genuinely well-written - man dnf5 is worth ten minutes if you live in this tooling.

Other Things Worth Knowing

A few smaller changes that don't deserve their own section but are worth a paragraph each.

MariaDB 11.8 is the new default. If you upgrade a server, run mariadb-upgrade afterwards to update the system tables. Don't skip this and then wonder why connections behave oddly.

Fedora Cloud images now use Btrfs subvolumes for /boot. Mostly invisible, but if you've got automation that assumes /boot is a separate ext4 partition, test before you redeploy.

OpenSSL added directory-hash support for ca-certificates. Faster certificate loading on systems with a lot of trust roots, no behaviour change for normal use.

Anaconda (the installer) now creates network profiles only for devices that are actually configured during install, instead of generating empty profiles for every NIC it sees. Cleaner, less to clean up.

QEMU 32-bit host builds are gone. Upstream deprecated them, Fedora followed. If you're running a 32-bit host (rare in 2026), this is your nudge.

Bootupd phase 1 begins. Boot loader updates start migrating to a unified mechanism. You won't notice unless something goes wrong, in which case the new tooling makes recovery cleaner.

How to Upgrade

If you're on Fedora 43, the upgrade path hasn't changed. Two ways to do it.

GUI: GNOME Software

Open Software, look for the "Fedora 44 is now available" banner, click the button, reboot when prompted. Easy mode. Works for the vast majority of desktops.

Terminal: dnf-plugin-system-upgrade

The reliable, scriptable path:

# 1. Make sure your current system is fully patched
sudo dnf upgrade --refresh
sudo systemctl reboot   # only if there are kernel/glibc updates

# 2. Install the system-upgrade plugin if you don't have it
sudo dnf install dnf-plugin-system-upgrade

# 3. Download the upgrade
sudo dnf system-upgrade download --releasever=44

# 4. Trigger the upgrade reboot
sudo dnf system-upgrade reboot

Step 3 takes a while - it's downloading a few GB of packages. Step 4 reboots into a special offline upgrade mode that runs the actual transaction. Coffee break, come back to a Fedora 44 login screen.

If something goes wrong during step 4, you'll boot back into your old system. That's a feature, not a bug.

Should You Upgrade?

For most desktops, yes, and there's no reason to wait. The release cycle stability has been good and the headline features (NTSYNC, GNOME 50, KDE 6.6) are user-facing wins.

For work machines, give it a week. Not because Fedora 44 is risky in itself, but because your toolchain might have rough edges with the new compiler versions. If you run a Ruby shop, run your test suite in a Toolbox container before you commit.

For servers, give it longer. Fedora is a leading-edge distribution by design. If you need long support windows and conservative changes, this is what CentOS Stream and RHEL are for. Test in staging, run for a fortnight, then upgrade prod.

For my own laptop, I'm pulling the trigger this evening.

Try This Before You Upgrade

If you want to kick the tyres without committing, the easiest path is a live USB. Download the Workstation ISO from getfedora.org, write it to a USB stick, boot from it, and have a poke around. Nothing touches your existing install.

The simplest path is Fedora Media Writer - it handles the download and the writing in one GUI flow, and it works on Linux, macOS, and Windows. If you'd rather use the terminal:

# Replace /dev/sdX with your USB device - check with lsblk first!
# status=progress and oflag=direct are optional; they just give you feedback and force direct I/O
sudo dd if=Fedora-Workstation-Live-x86_64-44-1.5.iso of=/dev/sdX bs=4M status=progress oflag=direct

You can run NTSYNC checks, test GNOME 50, and confirm your hardware works without committing to the upgrade. Five minutes well spent.

That's Fedora 44. Solid release, decent toolchain refresh, real gains for anyone running Wine or Steam. Worth the upgrade for most users, worth the planning for developers, and worth the staging-environment patience for servers. Same Fedora cadence, same predictable spring release, same weeks of polish ahead.
