Ubuntu 24.04 LTS, codenamed “Noble Numbat”, is here. This release continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, together with the community and our partners, to introduce new features and fix bugs.
Our 10th Long Term Supported release sets a new standard in performance engineering, enterprise security and developer experience.
Ubuntu Desktop brings the Subiquity installer to an LTS for the first time. In addition to a refreshed user experience and a minimal install by default, the installer now includes experimental support for ZFS and TPM-based full disk encryption and the ability to import auto-install configurations. Post install, users will be greeted with the latest GNOME 46 alongside a new App Center and firmware-updater. Netplan is now the default for networking configuration and supports bidirectionality with NetworkManager.
Ubuntu now enables frame pointers by default on 64-bit architectures to enable CPU and off-CPU profiling for workload optimisation, alongside a suite of critical performance tools pre-installed. The Linux 6.8 kernel now enables low-latency features by default. For IoT vendors leveraging 32-bit arm hardware, our armhf build has been updated to resolve the upcoming 2038 issue by implementing 64-bit time_t in all necessary packages.
As always, Ubuntu ships with the latest toolchain versions. .NET 8 is now fully supported on Ubuntu 24.04 LTS (and Ubuntu 22.04 LTS) for the full lifecycle of the release and OpenJDK 21 and 17 are both TCK certified to adhere to Java interoperability standards. Ubuntu 24.04 LTS ships Rust 1.75 and a simpler Rust toolchain snap framework to enable future rust versions to be delivered to developers on this release in years to come.
The newest Edubuntu, Kubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Cinnamon, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, Ubuntu Unity, and Xubuntu are also being released today. More details can be found for these at their individual release notes under the Official Flavours section:

Maintenance updates will be provided for 5 years for Ubuntu Desktop, Ubuntu Server, Ubuntu Cloud and Ubuntu Core. All the remaining flavours will be supported for 3 years. Additional security support is available with ESM (Extended Security Maintenance).
