Geospatial Analytics Extension version 2.0 released!

:earth_africa: Geospatial Analytics Extension for KNIME – Version 2.0

:tada: Release Summary

This major update introduces a range of powerful new nodes and improvements across the extension. Most notably, it upgrades the core GeoPandas library—the foundation for many of the extension’s geospatial features—from version 0.14 to 1.1.1.

The new GeoPandas version enhances robustness, flexibility, and performance for geospatial workflows. Because this underlying upgrade may result in subtle changes to node behavior, the extension’s version has been advanced to 2.0 to reflect the significance of this change.

This version requires KNIME Analytics Platform version 5.5.0 or later.
