The Cortex product documentation reflects the current SaaS product. It may require an upgrade for self-hosted customers to take advantage of the latest features, including new endpoints in the API.
For self-hosted customers, please contact the Cortex Customer Engineering team (help@cortex.io) to confirm the latest version or to subscribe to our weekly release notes which provide recent changes and the latest version number. New releases are generally available weekly on Tuesdays.
To check your current Cortex version in a self-hosted environment, navigate to Settings and scroll to the bottom of the settings sidebar in the Cortex UI.
