Steven Barrett has shipped Liquorix Kernel 7.2-1, a drop-in enthusiast-grade kernel built for gaming and audio/video workloads that pulls in upstream Linux 7.2.2. The release pushes Barrett's custom Project-C scheduler to the forefront, bringing wake-affine CPU placement, greedy task optimization, and heterogeneous core detection to Debian, Ubuntu, and Arch users. While the aggressive 2ms timeslices and near-RT preemption deliver snappier desktop responsiveness, they come at the cost of higher idle power draw, making this build best suited for desktops and workstations rather than laptops.
Steven Barrett's Liquorix Kernel just landed at 7.1-21, shipping two targeted patches that cap and properly drain the PDS scheduler's boost credit to stop unfair task hoarding. The release sits alongside a massive, ongoing Project-C rewrite that's been optimizing cache alignment, SMT awareness, and lock contention since mid-2026. It's an aggressive daily release cycle for a strictly AMD64-only package, but the work keeps the custom scheduler sharp for gaming and low-latency audio workloads. Security also got a facelift with AppArmor as default, Landlock enabled, and two CVEs backported into the mix.
Steven Barrett shipped linux-liquorix 7.1-20, merging upstream Linux 7.1.12 and refining the PDS sleep credit heuristic to balance scheduler fairness with low-latency performance. This twentieth build in under six weeks continues a rapid v7.1 series focused on Project-C scheduler maturation, hybrid CPU topology handling, and aggressive security hardening defaults. The project remains an AMD64-only enthusiast kernel that strips back power management and traditional preemptibility to prioritize frame-time consistency for gaming and audio workloads.
Canonical released Ubuntu 26.04.1 LTS "Resolute Raccoon," an updated installation medium loaded with security patches and bug fixes since the April 2026 baseline launch. The point release locks in Wayland as the default GNOME session, replaces legacy core utilities with Rust-backed alternatives like sudo-rs and Ptyxis, and jumps to GNOME 50. Server workloads gain PostgreSQL 18, a new LTS version of MySQL, and OpenSSH 10.2 with post-quantum cryptography enabled by default, while developers see GCC 15.2, Python 3.14, and .NET 10 arrive in the archive. Legacy X.org sessions and cgroup v1 support are gone, so users should wait roughly two weeks for the automatic upgrade prompt to clear out lingering rust-coreutils regressions before upgrading.
Liquorix has officially tagged linux-liquorix 7.1-19, building on the Linux 7.1.11 upstream base to deliver enhanced desktop responsiveness for gaming and audio workloads. The release introduces a new PDS scheduler "sleep credit" heuristic that boosts priority for interactive tasks waking from sleep, directly targeting frame-time stutter in games and audio buffer dropouts. Built on upstream Linux 7.1.11, the kernel also ships with extensive security hardening, including critical fixes for futex use-after-free vulnerabilities, HID subsystem bounds-validation flaws like a Joy-Con out-of-bounds read, and Bluetooth stack state corruption. Available for Debian, Ubuntu, and Arch, this drop-in kernel replacement prioritizes low-latency scheduling over raw throughput to keep interactive systems responsive.
XanMod has released updates for all three kernel branches with Edge moving to 7.2.1, Main to 7.1.11, and LTS to 6.18.47. The releases are heavily focused on security, bringing coordinated hardening patches for the futex subsystem to fix private hash resize races and significant fixes for HID drivers addressing out-of-bounds reads in Nintendo Joy-Con controllers and unbounded recursion in Magic Mouse drivers. Beyond security, the builds retain XanMod's standard LLVM ThinLTO optimizations and include third-party patchsets for Steam Deck support, AMD 3D V-Cache, and Google BBRv3, while the LTS branch adds legacy x86-64-v1 support for older hardware. Users should verify NVIDIA driver compatibility before upgrading, as the project warns that some DKMS modules may lag behind these new kernel versions.
Liquorix 7.1-18 is out, tracking the Linux 7.1.10 base and introducing "Project-C" scheduler micro-optimizations. The release drops two targeted patches that streamline a context switch lookup and correct a branch prediction hint on the non-migratable task path. Maintainer Steven Barrett continues his rapid August release cadence while bundling the standard low-latency defaults like hard kernel preemption and a 1000 Hz tick rate. AMD64 packages are available now for Debian, Ubuntu, and Arch via the official one-line install script.
Liquorix maintainer Steven Barrett released another kernel built on the upstream Linux v7.1.10 base. The update applies four cache-line-aware optimizations directly to the Project-C scheduler's hot paths, prioritizing data locality over algorithmic trimming. These changes specifically target context switch overhead and SMT idle coordination, making them most relevant for AMD Ryzen desktops running gaming or low-latency audio workloads. The release shipped just five hours after the base kernel merge, underscoring an active development pace that closely tracks upstream stable releases.
Steven Barrett has released Liquorix kernel 7.1-16, merging upstream Linux v7.1.10 with ongoing Project-C scheduler optimizations and standard security hardening. The update focuses on stability and incremental jitter reduction rather than introducing major new features, keeping the kernel tuned for interactive workloads like gaming and audio production. Available exclusively for AMD64 systems via a one-liner installer, the release builds on previous iterations by refining threading defaults and aligning Linux Security Modules with major distributions. While the non-LTS 7.1 tree means eventual upgrades are necessary, enthusiasts targeting low-latency desktop performance will find another reliable, polished iteration in the project's long-running track.
Ubuntu 26.10 "Stonking Stingray" officially crossed the feature freeze line on August 20, locking its software catalog and shifting development into a pure bug-fixing phase ahead of the October 15 launch. The interim release will ship with Glibc 2.44, an LLVM default compiler transition, and the latest GNOME stack, with no new functionality allowed past the cutoff. As a six-month interim drop, Stonking Stingray will only receive standard security support until July 2027, making the current LTS the better choice for production environments needing longer stability. The remaining development window includes a UI freeze on September 10, a mandatory beta on September 24, and a final release candidate on October 8 before the official ISO ships.
Liquorix 7.1-15 just shipped with eight targeted patches focused on Project-C's prio_balance() and context-switch hot paths. The release skips upstream feature backports in favor of cheap early returns and dead code elimination to shave microseconds off every scheduling decision. AMD64 users on Debian, Ubuntu, or Arch can grab the build with a one-line install script, though you'll be trading power efficiency for that signature low-latency responsiveness.
XanMod released version 7.2.0-xanmod1 of its Edge branch kernel on August 21, 2026, delivering a performance-focused rolling release for Linux power users. Key additions include full Steam Deck driver integration, native AMD 3D V-Cache optimization, and Google's BBRv3 as the default TCP congestion control for faster networking. The build utilizes LLVM with software pipelining and polyhedral loop optimizations, providing tailored packages for modern x64v2 and x64v3 microarchitectures. You can upgrade immediately by adding the official APT repository or downloading the .deb files directly from the XanMod GitLab releases page.
Liquorix Linux Kernel 7.1-14 arrived on August 19, 2026, merging the upstream Linux 7.1.9 base with a major security configuration overhaul. The update aligns the project's Linux Security Module settings with Arch, Debian, and Ubuntu defaults, enabling AppArmor as the primary access control system and adding Landlock sandboxing support. Performance tuning remains fully intact, keeping the PDS scheduler, 1,000Hz tick rate, and hard kernel preemption enabled for low-latency desktop workloads. You can install it today through the official auto-setup script, the Ubuntu PPA, or the Arch User Repository.
XanMod has released dual kernel builds, 7.1.9-xanmod1 and 6.18.45-xanmod1 with roughly 280 and 200 patches respectively. The update prioritizes network stack security and performance, packing in over forty networking fixes, OpenVPN hardening, and optimizations like Cloudflare TCP collapse and AMD 3D V-Cache support. Built exclusively for Debian and Ubuntu systems, the LTS branch extends support through December 2028 and retains a real-time variant, while the mainline tree focuses on bleeding-edge hardware for x86_64 v2 and v3 CPU profiles.
Steven Barrett has released Liquorix Linux Kernel 7.1-13, enabling threaded IRQs by default to minimize latency spikes and improve responsiveness for gaming and A/V production workloads. Built on upstream Linux 7.1.8, this release continues the maturation of the Project-C scheduler with optimizations like fork-aware runtime accounting and hard kernel preemption.
Steven Barrett has released Liquorix Kernel 7.1-12, continuing a rapid four-day iteration cycle with eleven targeted patches to Project-C, the project's custom sched/alt scheduler. The update prioritizes reduced task-switching overhead through improved fork handling, hybrid CPU idle-mask tracking, and atomic operation reductions designed specifically for gaming and audio production workloads. While AMD64 users can upgrade immediately via the official repositories, the project currently hosts several open AMDGPU stability reports that may warrant monitoring before switching from stock kernels. Users looking to install the latest build can pull it directly from the Debian, Ubuntu, or Arch Linux repositories today.
