 ## Bug fixes
 
 * Fixed a bug where the `separate_property_columns=True` option of `gds.graph.streamNodeProperties` did not handle list node properties correctly.
+* Fixed a bug where an irrelevant warning was shown when creating a `GraphDataScience` object targeting an AuraDS instance with GDS server version >= 2.1.0.
+* Fixed a bug where calling `gds.alpha.graph.construct` targeting an AuraDS instance would raise an exception.
