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:

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