Release Date: July/August 2025 (Largely retracted). Version 138 showed ambition to revolutionize cross-device continuity but faced technical challenges.

The "hero feature" was Desk Sync: the ability to work on Chromebook A and continue exactly where you left off on Chromebook B.

  • Technical Complexity: Synchronization of window layout, application position, and session cookies.
  • Cookie Sync Challenge: Securely transferring session tokens via the encrypted sync chain proved complex.
  • The Auth Incident: Users with third-party IdPs (like Clever) got stuck in an authentication loop. Google pulled the update for many devices.

AI Features: Help Me Read and Wallpapers

Despite the issues, v138 contained AI innovations for Chromebook Plus:

  • Help Me Read: Integration of Gemini Nano in the browser for web page summaries.
  • Generative Wallpapers: Expansion of personalization with text-to-image generation for backgrounds.

Web Platform

  • CSS progress(): Mathematical function for animations based on progress.
  • View Transitions API: Refinements for seamless transitions in Multi-Page Applications (MPA).
