    Build 29591 is not mentioned in the provided documentation. The latest Canary 29500-series builds covered are 29576.1000 and 29580.1000, which are part of the transition from the Canary 29500 series channel to the new Experimental (Future Platforms) channel.

    Key points from these notes that apply generally to new Canary/Experimental (Future Platforms) builds (including later ones like 29591) are:

    1. Canary/Experimental builds can be unstable and may ship with limited documentation.
    2. These builds represent early platform changes and are not tied to a specific future Windows release; features may change, be removed, or never ship broadly.
    3. Many features are rolled out via Controlled Feature Rollout, so availability can vary between devices.
    4. A desktop watermark in the lower-right corner is expected for Insider pre-release builds.
    5. To be among the first to receive new features, enable the toggle under Settings > Windows Update to get the latest updates as they are available.
    6. Transition off the Canary 29500 series channel to stable Windows requires a clean install of Windows 11.

    For a complete view of which build is in which channel, use Flight Hub.
