 # 0.55.1
 
+**If you are actively using the Model Control Plane features, we suggest that you directly upgrade to 0.55.1, bypassing 0.55.0.**

 This is a patch release bringing backwards compatibility for breaking changes introduced in **0.55.0**, so that appropriate migration actions can be performed at desired pace. Please refer to [the 0.55.0 release notes](https://github.com/zenml-io/zenml/releases/tag/0.55.0) for specific information on breaking changes and how to update your code to align with the new way of doing things. We also have updated our documentation to serve you better and introduced `PipelineNamespace` models in our API.
