To learn how to switch an existing SQL warehouse to the preview channel, see Preview Channels. Each new version will be announced in the following sections. From time to time, Databricks may promote a preview version to the current channel on a different schedule. Some features, such as security features, maintenance updates, and bug fixes, may be released directly to the current channel. Typically, a preview version is promoted to the current channel approximately two weeks after being released to the preview channel.

Take advantage of preview versions to test your production queries and dashboards against upcoming changes. Preview versions let you try out functionality before it becomes the Databricks SQL standard. Channels let you choose whether to use the Current SQL warehouse compute version or the Preview version.
