Ubuntu 25.10, codenamed “Questing Quokka”, 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, partnering with the community and our partners, to introduce new features and fix bugs.

Ubuntu 25.10 introduces GNOME 49 with media and power controls on the lock screen, HDR brightness settings, and enhanced accessibility features in line with the European Accessibility Act. New apps include Loupe, a modern image viewer, and Ptyxis, a lightweight terminal emulator.

Built on the Linux 6.17 kernel, this release brings nested virtualization on Arm, early Intel TDX host support for confidential computing, and enhanced support for TPM-backed full disk encryption with passphrase support, recovery key management and better integration with firmware updates. Network Time Security (NTS) is enabled by default for more secure time synchronization.

Developer experience advances with updated toolchains for Python 3.13.7 and availability of 3.14 RC3, GCC 15, Rust 1.85, Go 1.25, OpenJDK 25, and previews of .NET 10 and Zig.

Ubuntu 25.10 also debuts Rust-based implementations of sudo and coreutils for improved memory safety, and adopts the new RVA23 profile as the baseline for RISC-V, paving the way to Ubuntu 26.04 LTS.

The newest Edubuntu, Kubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Cinnamon, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, and Xubuntu are also being released today. More details can be found for these at their individual release notes under the Official Flavours section:

https://discourse.ubuntu.com/t/questing-quokka-release-notes/59220#heading–official-flavours

Maintenance updates will be provided for 9 months for all flavours releasing with 25.10.

Ubuntu 25.04, codenamed “Plucky Puffin”, 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, partnering with the community and our partners, to introduce new features and fix bugs.

Ubuntu 25.04 introduces GNOME 48 with triple buffering for smoother performance, HDR settings, and new features like a Wellbeing Panel and Preserve Battery Health mode. A new modern PDF reader, Papers, is now the default.

The installer now offers a smoother experience when installing alongside other operating systems, with better BitLocker support, and advanced partitioning.

Built on the Linux 6.14 kernel, this release brings a new scheduling system with sched_ext, enhanced Wine/Proton gaming support through the new NTSYNC driver, and better container tooling via decoupled bpftools and linux-perf.

Developer experience takes a leap forward with the introduction of devpacks. These snap bundles deliver the latest Go and Spring ecosystems, alongside updated toolchains for Python, Rust, .NET, LLVM, OpenJDK, and more.

Ubuntu 25.04 also expands confidential computing to on-premise environments with AMD SEV-SNP host support, and introduces a new ARM64 Desktop ISO for next-gen hardware.

Networking and identity management see continued improvements, including secure time sync with NTS, better Active Directory (AD) integration, cloud authentication against EntraID and Google identity, and DNS-aware wait-online logic with Netplan.

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:

Ubuntu 24.10, codenamed “Oracular Oriole”, 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, partnering with the community and our partners, to introduce new features and fix bugs.

Ubuntu 24.10 features the latest Linux 6.11 kernel for improved performance and hardware support, marking a shift to a more aggressive kernel version selection policy going forward.

Building on our previous LTS efforts around performance engineering, Ubuntu 24.10 now includes kdump-tools on relevant platforms for automatic kernel crashdumps. The default desktop installation also includes sysprof for application and workload profiling.

Ubuntu Desktop delivers GNOME 47 with improvements to performance, user experience and enhanced touchscreen support. The power-profiles-daemon improves power management for AMD CPUs and GPUs while libfprint adds support for many new fingerprint reader devices. Ubuntu Desktop now defaults to Wayland on devices with NVIDIA graphics cards and defaults to the NVIDIA 560 open driver version.

Snap management has also been improved on desktop with better update management and messaging in both the dock and the App Center, alongside an experimental new permissions prompting feature which can be enabled in the new Security Center application.

Valkey now replaces Redis in Ubuntu 24.10 with a configuration migration package to support the transition. As always Ubuntu provides updated toolchains for GCC, LLVM, Rust, Golang and .Net alongside TCK certified packages for OpenJDK 21 and 17.

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:
