ArcGIS Notebooks runtime versions 8 and 9

Description

ArcGIS Notebooks runtime versions 8 and 9 have been deprecated since June 2025 and October 2025 respectively and will be removed with the ArcGIS Online Q2 2026 update.

Recommendation

To avoid workflow disruptions, ArcGIS Notebooks users must take the following steps by June 2026: 

1. Review runtime version 
   • Go to your Notebooks home page and check the runtime version for each notebook under "My notebooks" or "Shared notebooks." A triangular caution sign indicates a deprecated runtime. 
2. Review and choose compatible runtime
   • Review the available Python libraries and their compatibility with different runtime versions.
   • Choose a runtime version that is compatible with your code, considering library availability and compatibility. 
3. Update runtime version
   • From the Notebooks homepage, select the notebook items to update and click "Update runtime.”
   • Alternatively, open the notebook's item page and navigate to the Settings tab.
   • Select the latest runtime version compatible with your code from the drop-down list.
4. Test your notebook 
   • After updating the runtime version, test your notebook to ensure it works as expected.
   • If the notebook has been published as a web tool, you must overwrite the web tool to update the runtime associated with it.
