Bazzite testing-45.20261102 updates to kernel 7.2.14-ogc4, PowerStation 0.9.0

Bazzite's testing branch has received a new build, testing-45.20261102, which advances the project's custom Linux kernel from 7.2.14-ogc3.1 to 7.2.14-ogc4 and upgrades PowerStation from 0.8.4 to 0.9.0. The release is an automatically generated changelog build for Fedora 45-based Bazzite, carrying forward existing versions of Mesa 26.2.6, Gamescope 3.17.0, MangoHUD 0.8.4, and the UMU Launcher 1.4.4 compatibility layer without changes.

This update targets users already on the testing branch who run Bazzite on Steam Deck, desktop gaming PCs, or handheld devices. The kernel revision and PowerStation bump suggest incremental refinement rather than feature introduction, with the distribution's core gaming stack—Proton via UMU, Gamescope compositor session, InputPlumber controller abstraction, and OpenGamepadUI frontend—remaining at previously established versions.

Kernel and system component changes

• Kernel (OGC): Updated from 7.2.14-ogc3.1 to 7.2.14-ogc4, a minor revision bump on the Open Gaming Core branch maintained by the Bazzite project.
• PowerStation: Upgraded from 0.8.4-2 to 0.9.0-1, representing a minor version increase for this power management and performance profiling utility.
• qt6-controllable: Rebuilt from 0.2.0-1 to 0.2.0-2 across all images, indicating a packaging or dependency revision with no upstream version change.
• Nvidia driver stack: Retains dual-track support with Nvidia Open 615.78.08 and Nvidia LTS 580.196.07, plus a separate Waydroid Nvidia compatibility package at 0.1.2-3.
• Gaming middleware: Gamescope 3.17.0, MangoHUD 0.8.4, UMU Launcher 1.4.4, and sched_ext Schedulers 1.1.4 all carry over unchanged from the previous testing build.

Why it matters

For Linux gamers running Bazzite on Steam Deck or custom builds, this testing update offers a low-risk path to validate kernel and power management fixes before they reach stable. The OGC kernel's continued evolution matters for hardware enablement on handhelds where upstream Fedora kernels often lag, while PowerStation's 0.9.0 release may refine battery life and thermal behavior on AMD and Intel portable devices. The unchanged Mesa and Gamescope versions suggest this is not a graphics-focused release, keeping the testing branch's role as a staging area for incremental system-layer changes rather than gaming feature delivery.
