Ubuntu 24.04.3 LTS (Noble Numbat) continues the legacy of Canonical’s Long-Term Support releases, bringing stability, security, and updated software to both desktop and server environments. This third point release includes all security updates and hardware enablement stacks from previous updates, making it an excellent choice for new installations or upgrades from older Ubuntu versions.
What’s New in Ubuntu 24.04.3 LTS?
Ubuntu 24.04.3 LTS is not a major feature release, but rather a cumulative update that bundles all patches, kernel updates, and hardware support improvements since the original 24.04 launch in April 2024. Key highlights include:
- Updated Linux Kernel 6.14 (via Hardware Enablement Stack) for better support of 2025 hardware.
- Mesa 25.0 Graphics for improved gaming and rendering on AMD/Intel chips.
- Security patches backported to all core packages.
- No major interface changes — retains GNOME 46 with Ubuntu’s customizations.
