Open the version history from the history icon next to an environment in **Settings** → **Environments**. ![Version History 2](/docs/images/Version-history-2.png) Each entry shows the version number, description, author, and publish time. The **Live** label marks the version your users currently interact with. Click any version to open a comparison against the live version of the environment. From there you can: - Click **Revert** to make the selected version live again. A new version is added to the history with a description noting which version you reverted from. - Click **Clone to new environment** to create a new environment starting from the selected version. ![Revert](/docs/images/Revert.png) Reverting only affects the environment you revert on; other environments are unchanged. Reverting restores content, not credentials: the environment keeps its current [secret values](/docs/documentation/build/data/secrets#publishing-reverting-and-discarding-changes).
