Preview features

New features are sometimes released as preview features. Preview features are available to try, but they might have limited functionality, and some aspects might change before the feature is released systemwide. Preview features are not always released to all Tungsten AP Essentials users at once. They are selectively enabled on only a fraction of all accounts, or a preview feature can be restricted to a single customer. Releasing features on a preview basis is helpful to users and Tungsten AP Essentials development because it gives users a chance to test drive new features and provide vital feedback that can improve the feature before it is finalized and released to all users. Preview features are announced in What's new. Announcements are also made in What's new when a preview feature is elevated to general availability for all accounts.
