Go to [**Map Styles**](https://console.cloud.google.com/google/maps-apis/studio/styles), and select a project, if needed.\n2. Select an existing map style.\n3. Select **Customize**.\n4. Select **Version history**.\n\nVersion history is divided into different types:\n\n- As **Drafts**\n - Selecting **Save** creates new dated versions. Saved drafts are not usable in your apps until they are explicitly published.\n - Changes you make without saving create an **Unsaved changes** draft that are lost if you close your browser window or end your session.\n- As **Published Versions**\n - When you create a new map style, duplicate an existing style, or import a JSON style, it is published automatically.\n - Selecting **Publish** creates new dated versions that are available for use in your apps. The most recent published version is applied to any apps with the associated map IDs.\n\nYou can view any previous version in **Version history** .\nTo reuse a version and make changes to it, you must\neither **Restore** the version, which sets that version to be the current,\nactive version of the map style, or **Duplicate** it, which creates a new,\nseparate map style based on that version.\n\nIf you have unsaved changes when you restore any version, those unsaved changes\nautomatically become a new dated draft version.\n| **Important:** When you **Publish** any map style associated with one or more map IDs, that style's latest published changes are visible in all apps using map IDs associated with that map style. Until your style changes are complete, **Save** rather than **Publish** your style changes.\n\n### Duplicate a map style version\n\n1. Go to [**Map Styles**](https://console.cloud.google.com/google/maps-apis/studio/styles), and select a project, if needed.\n2. Select one of your existing styles, and click **Customize**.\n3. Select **Version history**.\n4. Select a style version, and then at the bottom of the **Version history** pane, select **Duplicate**.\n5. The style is duplicated with \"Copy of\" added to the style name.\n\nThe duplicated style is automatically published and you get a link to open\nthe new style in a new tab.\n| **Note:** A duplicated style does not retain the versions of the style it duplicated.\n\nRestore a map style version\n---------------------------\n\nIf you want to use a previous version of a map style, you can restore it.\nFor example, if you created a branded map style to support a special event,\nwhen the event is finished you can restore the standard version of the\nmap style.\n\n1. Go to [**Map Styles**](https://console.cloud.google.com/google/maps-apis/studio/styles), and select a project, if needed.\n\n2. Select the style you want, and select **Customize**.\n\n3. Select **Version history**.\n\n4. Select the version you want to restore, and at the\n bottom of the **Version history** pane, select **Restore**. The restored\n style becomes the most recent draft of the style.\n\n5. Close the **Version history** pane, and select **Publish**.\n\n | **Note:** Style changes can take a few hours to propagate to your apps websites, and apps can take longer if the devices aren't connected to the internet. If you're still not seeing your style changes after a few hours, see [My style changes aren't updating](/maps/documentation/android-sdk/cloud-customization/troubleshoot#style-delay).\n\n| **Note:** If the restored version is exactly the same as the published version, you can't publish the restored version. If you still want to publish the draft of the restored version, even if it's identical to the published version, you must modify the style in some way, then select **Save** and then **Publish**."]]
