ArcGIS GeoAnalytics for Microsoft Fabric currently is included in Microsoft Fabric’s Runtime 1.3 and 2.0. As of September 30, 2026, the Fabric Runtime 1.3 will be at End of Support, with Long Term Support (LTS) continuing for a period of six months (through March 2027). Fabric’s Runtime 2.0 will become the default Runtime and is the Runtime that should be used for working with GeoAnalytics for Fabric moving forward. For more information on Fabric Runtime support, please see Microsoft’s Lifecycle of Apache Spark runtimes in Fabric documentation.
Action: To update now and test your notebooks using GeoAnalytics for Fabric in the new Runtime 2.0, you should manually change the environment to Runtime 2.0.
Once the Runtime 1.3 deprecation takes place, notebooks using the default runtime should automatically update to Runtime 2.0 when that becomes the default to replace Runtime 1.3. At that time any new notebooks or workspaces would also automatically be created using Runtime 2.0. If you work with custom environments, you may need to re-publish your Environment (including any libraries). Details on this, and on processes for updating the Runtime used in your notebooks, are included in the specifications for Runtime 2.0.
While we do not anticipate impacts to your notebooks using GeoAnalytics for Fabric functionality, you should test your notebooks in Runtime 2.0 prior to the full deprecation of Runtime 1.3 to evaluate for potential impacts on your workflows due to the broader changes in Runtime environment. Note that Runtime 2.0 introduced core updates to the Spark version (3.5 vs. 4.1) and moved to use Delta Lake 4.2 and Python 3.13. These may cause breaking changes or behavioral shifts in your notebooks outside of the GeoAnalytics for Fabric library functionality.
Details on the latest version of GeoAnalytics for Fabric can be found in our Developer documentation.
Let us know in the comments if you have any questions or experience challenges with the update to Runtime 2.0.
