Silent Update System — General Documentation


The Silent Update System is a Reacts mechanism designed to maintain the Reacts application up-to-date. The service allows Philips to deliver security and feature updates in a way that is fast, transparent, consistent, reliable and secure.


The Silent Update System automatically downloads and prepares new versions of the Reacts application in the background. As soon as the user closes and re-opens the Reacts application, the latest version is launched. The system has no impact on the end-user: the updates are applied without generating any interruption whatsoever.


Delivery Frequency


By default, all new Reacts installations are subscribed to the Fastlane. Clients that subscribe to the Fastlane will receive Reacts updates as soon as they are stable and released to the public. Clients that subscribe to the Fastlane will benefit from the most up-to-date security and features. 

Clients subscribe to the Fastlane automatically during the normal installation of the application.
