Ready for an Upgrade? Why Ubuntu 24.04.3 is the Game-Changing OS You Need
Canonical released the third update for its long-term support version, Ubuntu 24.04.3, on August 8, 2025. This version, known as “Noble Numbat,” brings a collection of updates to the desktop, server, and cloud products. Think of a point release as a refreshed installation disc. It bundles all the security patches, bug fixes, and software updates that have been released since the last version. This is a huge help for anyone performing a new installation, as it saves them from downloading a massive amount of updates right after setting up the system.
For those who already have Ubuntu 24.04 LTS installed and regularly update their system, there is nothing new in this release you don’t already have. The main goal is to ensure stability and maintain compatibility with the original 24.04 LTS release.
Key Improvements and What They Mean for You
This update is packed with enhancements aimed at improving performance, security, and hardware compatibility. It now runs on the newer Linux kernel 6.14 and includes the Mesa 25.0 graphics stack. These are back-ported from the more recent Ubuntu 25.04, which means your system gets better support for modern hardware, especially newer graphics cards and processors.
Key software packages have also been updated:
- LibreOffice 24.8.7
- Firefox 141
- snapd 2.68.5
The desktop experience sees several improvements, especially for users of the default GNOME environment. The Mutter window manager and Nautilus file manager have received updates to fix stability issues and crashes. For instance, problems with dragging and dropping between applications and touchscreen responsiveness have been addressed. Additionally, updates to GTK4 improve how Unicode emojis are handled and enhance integration with the Orca screen reader, making the desktop more accessible. The Pipewire audio server was also updated to fix issues with sound playback.
Important Bug Fixes
A significant number of bug fixes are included in this release, addressing issues that users have reported. These fixes improve the overall user experience by resolving annoying glitches and serious security vulnerabilities. Some of the notable fixes include:
- Resolving an issue where the “install” button would sometimes disappear in the software updater.
- Fixing missing thumbnail previews on the desktop.
- Correcting problems with Bluetooth audio connections.
- Addressing crashes in the Nautilus file manager and Mutter window manager.
- Improving support for various hardware components, including certain Wi-Fi adapters, fingerprint readers, and audio codecs on specific laptop models.
Support for Ubuntu Flavors
The update isn’t just for the main version of Ubuntu. All official “flavors” have also been updated to version 24.04.3 LTS. These include:
- Kubuntu
- Ubuntu Budgie
- Ubuntu MATE
- Lubuntu
- Ubuntu Kylin
- Ubuntu Studio
- Xubuntu
- Edubuntu
- Ubuntu Cinnamon
- Ubuntu Unity
It is important to note the difference in support duration. While the main Ubuntu Desktop with GNOME receives five years of standard support until April 2029, most other flavors are supported for three years. For those needing support beyond the standard period, Canonical offers Extended Security Maintenance (ESM) through an Ubuntu Pro subscription, which can extend security coverage for up to 10 years in total.
