Post-release news (26.04)

This page collects the major news from Canonical, the upstream kernel, the community, and the broader ecosystem after Ubuntu 26.04 LTS shipped. Newest items come first. When an item changes shipped component versions, the details are folded back into Release Highlights and Point Releases.

September 2026

September 2 — Ubuntu 26.10 Snapshot 3 released

The third — and possibly final — monthly snapshot of Ubuntu 26.10 “Stonking Stingray” is available. There were no monthly snapshots in July or August; the beta is scheduled for September 24, with the final release on October 15.

Snapshot 3 highlights:

• Key parts of GNOME 51 beta/RC are present, along with default-app updates such as Papers (visual signatures) and Loupe (software/lens metadata)
• The official manifest still shows Linux 7.0.0-14 (the 26.04 HWE kernel), not Linux 7.2 as reported by OMG! Ubuntu; the final kernel will be confirmed after the October 1 kernel freeze
• Myna voice typing is not yet included in the snapshot or daily builds
• Snapshots are test-only “throwaway artifacts”, not production builds

September — amd64-v3 installer in 26.10 daily ISOs

Ubuntu 26.10 daily ISOs now offer an x86-64-v3 optimized package set (stonking-desktop-amd64v3.iso) out of the box, so no post-install conversion is needed. 26.04 LTS keeps the standard amd64 (v1) baseline; most Intel/AMD CPUs from 2015 onward with AVX2/FMA/BMI1/2 are v3-compatible.

August 2026

August 27 — Ubuntu 26.04.1 LTS released

Ubuntu 26.04.1 LTS (Resolute Raccoon) was released on August 27, 2026 as the first point release of 26.04 LTS. It adds no new features; it refreshes the installation media and integrates all security updates and bug fixes up to August 25, 2026.

Highlights:

• Installer/upgrader: ubuntu-release-upgrader now sets Prompt=lts for resolute and fixes the rust-coreutils regression that blocked upgrades; netboot permissions and nocloud password data format were also fixed
• Desktop: GNOME Shell search providers being removed, Mutter multi-monitor hot-plug/cursor/drag-and-drop, GTK4 memory corruption, GNOME Control Center autostart toggles, PackageKit TOCTOU
• Server/cloud: QEMU/libvirt HWE, systemd postinst with rsyslog, rsync security regression, Exim4
• Kernel remains the Linux 7.0 series (image 7.0.0-30); Mesa 26.0.8, GNOME Shell 50.1; no new HWE stack — 26.04.2 (February 2027) will bring the Ubuntu 26.10 kernel/GPU stack
• TPM-backed FDE: the mandatory PIN can now be disabled on hardware whose firmware cannot be verified automatically (this lowers tamper protection)
• Existing installs only need sudo apt update && sudo apt full-upgrade; new installs should use the 26.04.1 ISO
• Automatic upgrade prompts for 24.04 LTS are expected about two weeks after the release (early September 2026); do-release-upgrade -d works immediately

August 24 — Ubuntu 26.10 feature freeze announced

Ubuntu 26.10 entered feature freeze on August 20, with the formal announcement following on August 24. Development focus shifted from landing features to bug fixing; major changes now need a Feature Freeze Exception (FFE). GNOME 51, more Rust tooling, and GPU driver management in App Center are among the 26.10 highlights.

August — Ubuntu AI voice typing “Myna” demoed

Canonical’s AI speech-to-text tool Myna was shown publicly for the first time: press a hotkey and dictate into any text field via IBus. The GNOME Shell indicator extension is already in default installs, but Myna itself is not yet in Snapshot 3 or the daily builds.

July 2026

July — dbus-daemon retires, dbus-broker becomes the default

Starting with Ubuntu 26.10, both the system and user buses use dbus-broker; after 22 years, dbus-daemon steps aside. Users should notice nothing, but reliability and message delivery under heavy load improve.

July — Ubuntu Certified check comes to Settings

26.10 adds a “check if this computer is Ubuntu Certified” row to Settings > System > About, reading a local/cached status via com.ubuntu.hwctl, with an optional recurring check. The hwlib CLI remains available.

June 23 — Canonical promotes Arm64 Livepatch to GA

Canonical’s Livepatch service has reached GA on Arm64. AMD64 Livepatch has been available for years, and 26.04 LTS shipped initial ARM64 Livepatch support at GA in April (see Release Highlights), but the full GA-quality rollout — including Ubuntu Core 26 and an Arm64 regression test suite on par with AMD64 — is dated to this June 23 announcement. Ubuntu Core 20+ on AMD64 is included in the same announcement. Affected systems can apply critical kernel updates without a reboot or service interruption — an important capability for edge devices and large Arm-based cloud fleets, and a direct enabler for the EU Cyber Resilience Act (CRA) compliance push.

Reaching this milestone required native Arm64 build farms and an architecture-specific regression test suite on par with the existing AMD64 pipeline. Livepatch ships as part of Ubuntu Pro (free for personal use on up to 5 machines).

June 16 — Ubuntu Core 26 local AI inference reference

Canonical demonstrated a reference “AI box” workflow running on Ubuntu Core 26 inside Multipass with the gemma4 snap for local inference. The target is edge AI / IoT gateways, kiosks, and robotics — appliances rather than general-purpose desktops.

Minimum bootstrap (matches the official blog; defer to the latest version of the source):

multipass launch core26 -n aibox --cpus 4 --memory 10GB --disk 16GB
multipass exec aibox -- sudo snap install gemma4
multipass exec aibox -- sudo gemma4 set http.host=0.0.0.0 webui.http.host=0.0.0.0

Two endpoints are exposed:

• http://<ip>:8336/v1 — OpenAI-compatible inference API
• http://<ip>:8337 — browser WebUI

Desktop users who want a more general local model stack should still look at the Ollama / LM Studio / llama.cpp section in Local LLMs.

June 15 — Linux 7.1 kernel released

Ubuntu 26.04 LTS still ships Linux 7.0 as the GA kernel, but Linux 7.1 is out upstream. By Ubuntu’s historical cadence the new HWE stack rolls with the second point release — so the 26.04.2 HWE kernel (~February 2027) is the likely landing spot for the 7.1 series; 26.04.1 (August 2026) typically keeps the GA kernel. Highlights:

• Rewritten NTFS driver by Namjae Jeon (author of the kernel exFAT driver), with write support, iomap-based file operations, and a corruption-repair tool.
• exFAT preallocation to reduce fragmentation on large writes.
• Btrfs close path promoted from experimental to stable.
• Intel FRED — faster CPU privilege transitions; 4–7% gains observed in audio workloads.
• AMD dynamic EPP — power profile auto-switches between performance and balanced.
• Parallel swap-in/out operations.
• Apple Silicon — MacBook battery reporting driver and 6-codec speaker topology support.
• Steam Deck OLED audio fix.
• Ryzen AI NPU — power and utilisation monitoring.
• Legacy AMD A/E-series GPUs migrated onto the modern amdgpu driver.
• Tighter cross-process memory access — non-debugger processes can no longer freely read or write each other’s memory.
• 140,000+ lines of legacy code (ISDN, amateur radio drivers, etc.) removed.

June 8 — Flathub tightens AI-generated-app policy

Flathub now bans purely AI-generated submissions to the store — manifests, metadata, patches, build scripts, and PRs produced by automated AI agents are not accepted. Existing “vibe-coded” apps already on the store are not retroactively removed, and well-maintained mature projects may apply for exceptions based on CI, release cadence, and community activity. Impact on end-users is minimal; the goal is to stop low-effort clones from burning volunteer reviewer bandwidth.

June — Mandatory Beta for Ubuntu flavours

Canonical clarified that, starting with the 26.10 cycle, every official flavour (Kubuntu, Xubuntu, Ubuntu MATE, Ubuntu Studio, Ubuntu Kylin, Ubuntu Cinnamon, …) must submit a Beta on schedule to qualify for the final release manifest. Ubuntu Kylin had previously shipped 26.04 LTS despite missing its Beta — that exception is gone. Daily builds reach too few testers, so the requirement is meant to surface more bugs before GA.

June — Ubuntu 26.10 plans “Talk-to-type” voice input

Canonical VP of Engineering Jon Seager confirmed that Ubuntu 26.10 will add a desktop-wide voice-input shortcut: press a button and dictate into any text field. The implementation is based on local language models such as Whisper. All AI capabilities will ship as removable Snaps, preserving an explicit kill-switch. Default-on status and toolkit integration are still being worked out.

May — ONLYOFFICE 9.4 released

ONLYOFFICE desktop editors moved to 9.4 with strengthened open-source licensing and collaboration. It remains a key Office-replacement option on 26.04 — install via sudo snap install onlyoffice-desktopeditors or the deb package.

Watch list

• 26.04.2 HWE kernel — 26.04.1 (August 27, 2026) still uses the Linux 7.0 series (7.0.0-30) and does not introduce a new HWE stack; the new HWE stack arrives with the second point release (~February 2027), backported from 26.10.
• Ubuntu 26.10 Stonking Stingray — feature freeze done (August 20), Snapshot 3 out (September 2); UI freeze September 10, beta September 24, GA October 15. GNOME 51, dbus-broker, OpenSSL 4.0.1 and amd64-v3 ISOs are confirmed; Myna is not in the snapshots yet. See Ubuntu 26.10 progress.
• Arm64 Livepatch back-coverage — waiting on a public timeline for 22.04 LTS and 24.04 LTS.
