 ## How to call a preview REST API
 
 Azure Cognitive Search always pre-releases experimental features through the REST API first, then through prerelease versions of the .NET SDK.
 
-Preview features are available for testing and experimentation, with the goal of gathering feedback on feature design and implementation. For this reason, preview features can change over time, possibly in ways that break backwards compatibility. This is in contrast to features in a GA version, which are stable and unlikely to change with the exception of small backward-compatible fixes and enhancements. Also, preview features do not always make it into a GA release.

Also, preview features don't always make it into a GA release.
 
 While some preview features might be available in the portal and .NET SDK, the REST API always has preview features.
 
 + For search operations, [**`2021-04-30-Preview`**](/rest/api/searchservice/index-preview) is the current preview version.
 
 + For management operations, [**`2021-04-01-Preview`**](/rest/api/searchmanagement/management-api-versions) is the current preview version.
 
-Older previews are still operational but become stale over time. If your code calls `api-version=2019-05-06-Preview` or `api-version=2016-09-01-Preview` or `api-version=2017-11-11-Preview`, those calls are still valid, but those versions will not include new features and bug fixes are not guaranteed.
