+- [GeoMap visualization will ignore points with `null` coordinates][1775]. Now
+  the presence of such points in the dataset will not break initial map
+  positioning.
 - [Updated Enso engine to version 0.2.11][1798]. If you're interested in the
   enhancements and fixes made to the Enso compiler, you can find their release
   notes [here](https://github.com/enso-org/enso/blob/main/RELEASES.md).
