"Version 0.2 appeared on September 6. As Linux benchmarking site Phoronix reports, the big gains are in performance. Until recently, the new Rusty tools were about ten times slower than the traditional GNU versions implemented in C, but as of this release, they have leapfrogged the older versions and are now 50 percent faster. This probably won't make much visible difference to most people in daily use, but safer and faster sounds like a good combination."
"The work-in-progress release notes contain some more nuggets of info. The TPM-backed full-disk encryption, which we covered in July, seems to have made it in, because there's at least one outstanding bug. Although it has yet to see a finished release, the latest builds use kernel 6.17. This means there's a small risk that Questing will ship with a release candidate kernel, and get updated to the final version post-release."
Ubuntu 25.10 'Questing Quokka' has moved from Feature Freeze to UI Freeze. The release replaces several GNU utilities with Rust implementations and already includes sudo-rs. Rust Coreutils v0.2 showed major performance gains, reversing prior slowness and running about 50 percent faster than GNU equivalents; v0.2.2 followed shortly. Recent builds use kernel 6.17, creating a small risk that a release candidate kernel could ship and later be updated. TPM-backed full-disk encryption appears present but has at least one outstanding bug. Questing is an interim nine-month release with end of life in July 2026.
