Ubuntu 26.10’s beta brings a Rust-based core utilities implementation and official RVA23 RISC-V support. The release gives developers and testers a look at significant changes to Ubuntu’s foundations ahead of the planned 15 October final release.
Watch Desk analysis
What happened
Canonical has released the Ubuntu 26.10 beta, codenamed “Stonking Stingray”. LinuxCompatible reports that it includes a fully Rust-based coreutils implementation, official RVA23 RISC-V support, the Linux 7.3 kernel release candidate and GNOME 51. The beta arrived a week later than originally planned, according to the report.
Other reported changes include GCC 15.2.0, Rust 1.97.1, Python 3.14.7, Mesa 26.2 and the dbus-broker messaging implementation. Read LinuxCompatible’s report.
Our top picks
- Rust-based coreutils
The beta completes Ubuntu’s transition to core utilities implemented in Rust. - Official RVA23 RISC-V support
The release adds a defined route for this RISC-V platform to Ubuntu. - Linux 7.3 release candidate
Testers get an early look at a newer kernel, rather than its eventual stable version. - GNOME 51
The beta brings the next desktop environment version into Ubuntu’s testing cycle. - Refreshed developer tools
GCC 15.2.0, Rust 1.97.1 and Python 3.14.7 are included.
Why it matters
This beta combines changes to system utilities, hardware support and the desktop, making it more than a routine version-number turn. Rust-based core utilities and official RVA23 support are especially concrete signals for developers and people testing Ubuntu on RISC-V systems.
It is still a beta, and the kernel listed is a release candidate. Treat this as a chance to test and report problems, not a recommendation to swap out a dependable machine before the final release.
Our read
There is enough here to make the beta worth a look, particularly for developers tracking Rust in foundational Linux software or testing RISC-V support. The sensible move is to try it on a spare system or in a virtual machine, and leave the mission-critical laptop out of the experiment.
What to watch
- Whether the Rust-based coreutils implementation or RISC-V support changes before the final release.
- Whether the final release lands on the reported 15 October target.
- What beta testers find in the new desktop, kernel and hardware support.
Discussion spark: Should a distribution move core utilities to Rust in one broad transition, or keep both implementations available until compatibility has been tested for longer?
