    > [!TIP]
    > The Azure Virtual Desktop Agent download link is for the latest production version in [non-validation environments](terminology.md#validation-environment). This download link is updated after the automatic production rollout is complete, so you might see a delay between the release of a production version and the update of the download link. After you install the Azure Virtual Desktop Agent, it's updated automatically. For more information about the rollout of new versions of the agent, see [What's new in the Azure Virtual Desktop Agent?](whats-new-agent.md#latest-available-versions).
