Stonking Stingray Surfaces: Ubuntu 26.10’s Security Overhaul and Six-Month Sprint to October Launch

Canonical has pinned October 15, 2026, as the launch date for Ubuntu 26.10, codenamed Stonking Stingray. This interim release—Canonical’s 45th—kicks off its development cycle on April 30, just days after the fresh Ubuntu 26.04 LTS rollout, and promises nine months of support through July 2027. Developers and early adopters get a beta on September 24 for testing. Feature freeze hits August 20. The official timetable, straight from Ubuntu documentation, lays out user interface freeze on September 10, kernel freeze October 1, and final tweaks by October 8.

Expect GNOME 51, timed for September 16, to refresh the desktop. Linux kernel 7.2 should land too, aligning with its late-August debut, as noted by 9to5Linux. But security grabs the spotlight. GRUB gets gutted in signed builds. No more XFS, ZFS, Btrfs, LVM, md-RAID beyond RAID1, or LUKS parsing. Ubuntu developers call these parsers a “constant source of security issues.” The fix? Strip them to boost protection, especially for encrypted setups, forcing an unencrypted EXT4 /boot partition. Want full features? Ditch signed GRUB and Secure Boot. Details emerged in an Phoronix report on Canonical’s Discourse plans, with upgraders from 26.04 LTS set to block risky configs.

Rust takes center stage next. Ubuntu 26.04 LTS already mixes in Rust coreutils at version 0.8, but cp, mv, and rm stick with GNU due to time-of-check-to-time-of-use bugs. An independent audit by Zellic uncovered 44 CVEs and 113 issues total—most fixed now. Canonical eyes full replacement in 26.10. “100% Rust Coreutils,” they aim, per a Phoronix article citing Ubuntu’s Discourse update. Memory safety wins. Maintenance eases. But pre-1.0 versions raise eyebrows among some engineers.

And the cycle rolls on. Interim releases like this one let Canonical test bolder moves before LTS lock-in. Think back to Ubuntu 18.10, the first Yaru-themed drop on October 15 too. Stonking Stingray overlaps 26.04 LTS support by three months, easing upgrades for the impatient. OMG! Ubuntu flagged the no-frills GRUB early, tying it to encrypted install gains. Optional testing weeks in July and August invite community input.

But trade-offs loom. ZFS fans grumble over boot constraints. Secure Boot purists face choices: slim GRUB or skip it. Rust’s audit exposed real flaws—70 CVEs, 73 issues logged—yet Canonical pushes ahead, betting on fixes. GNOME 51 and kernel 7.2 bring hardware perks, but nine-month support suits tinkerers, not enterprises clinging to LTS stability.

Development starts tomorrow, post-26.04 LTS. Toolchain pulls from Resolute Raccoon. Beta testers, mark September. Final push in October. Stonking Stingray stings with changes. Security tightens. Rust dominates. The sprint begins.
