-### Major changes
+### Important
-- None
+This release fixes a longstanding issue with the provider namespace flag. Previously, this
+flag was erroneously ignored, but will now cause any resources using this provider to be
+created in the specified namespace. **This may cause resources to be recreated!** Unset the
+namespace parameter to avoid this behavior. Also note that this parameter takes precedence
+over any namespace defined on the underlying resource.
-### Improvements
+The Python SDK now supports YAML manifests and Helm charts, including `CustomResourceDefinitions`
+and `CustomResources`!
+
+### Major changes
- Put all resources in specified provider namespace (https://github.com/pulumi/pulumi-kubernetes/pull/538)
- Add Helm support to Python SDK (https://github.com/pulumi/pulumi-kubernetes/pull/544)
