There are three tracks offered as part of release management:

1. Continuous track: products are on the continuous release track by default. They receive changes and features as soon as they become available.
2. Preview track: this track is only available for a sandbox environment. Products on the preview track will receive the same changes as products on the continuous track, but they receive them as a group, every two weeks.
3. Bundled track: products on the bundled release track will receive the same changes as products on the continuous track, but they receive them as a group, every two weeks with an additional two weeks of delay.

Preview Tracks are only available for sandboxes however some customers have their test environments (Non Sandbox) where they wish to enable Preview Track Feature.

For such edge customers, we can have a Feature Flag or something similar that enables Preview track for their Non Sandbox instances.
