Google rolls out November update for Googlebook with memory, Chrome, and security fixes

Google is rolling out its November update for Googlebook, bringing changes meant to make the platform more reliable and less frustrating to use. The update frees 3GB to 6GB of system RAM by updating the NPU driver and optimizing AICore memory management, while also improving Chrome behavior under heavier workloads. Google says the release is being rolled out gradually to supported models from Acer, ASUS, Lenovo, HP, and Dell.

Memory and Chrome improvements

The biggest change involves memory used by on-device AI services. Google updated its NPU driver and optimized AICore memory management, freeing 3GB to 6GB of system RAM, according to a Reddit post by Google's Mishaal Rahman. The company says that amount is especially significant for laptops with 16GB of RAM when switching between many apps and browser tabs. Chrome should also behave better under heavier workloads because the update improves how the system reclaims memory when background AI services conflict with browser processes, reducing unexpected tab reloads and crashes.

Hardware and connectivity fixes

The November release also covers a range of hardware and software issues. Convertibles should no longer lose keyboard and touchpad input when switching between tablet and laptop modes. Google fixed Zoom crashes involving simulated backgrounds, filters, blur effects, and 3D avatars. External displays can now play DRM-protected streaming content such as Netflix instead of showing a black screen. USB microphones and multichannel audio interfaces should work as expected, while Bluetooth users may see lower audio-video synchronization delays and more reliable reconnection for wireless mice.

Linux and security updates

Developers get several Linux Terminal beta fixes, including more reliable shell sessions after sleep, better SSH port forwarding, and improved multi-window management. Google also fixed a memory leak when closing terminal tabs and made Linux VM updates less destructive, preserving user storage and custom SSH configurations. On security, the Android security patch for November 1, 2026 resolves around 60 vulnerabilities. Google also updated the Linux 6.18 kernel and Ti50 security chip firmware, addressing unexpected restarts, boot loops, and noisy fans.

Rollout and early reactions

Owners can find the update under Settings, System, System Update, and should look for build number CL3B.260622.286.R2. Early Reddit reactions have been largely positive, with some owners reporting smoother performance. Some users are also reporting issues, including Chrome spell check and notification syncing problems after waking from sleep.
