0.45.1 [YANKED]

0.45.1

Update: It's one of those days! This release is also yanked due to alembic migration issues. We are working hard to solve it. In the meanwhile please use 0.44.3

This release replaces 0.45.0, and fixes the major migration bugs that were in that yanked release. Please upgrade directly to 0.45.1 and avoid upgrading to 0.45.0 to avoid unexpected migration issues.

What's changed

This release introduces a major upgrade to ZenML, featuring a new authentication mechanism, performance improvements, the introduction of the model control plane, and internal enhancements.

New Authentication Mechanism (#4303)

Our improved authentication mechanism offers a more secure way of connecting to the ZenML server. It initiates a device flow that prompts you to log in via the browser dashboard:

zenml connect --url <YOUR_SERVER_URL>

This eliminates the need for explicit credential input. The previous method (zenml connect --url <URL> --username <USERNAME> --password <PASSWORD>) remains operational but is less recommended due to security concerns.

Critical This change disrupts existing pipeline schedules. After upgrading, manually cancel and reschedule pipelines using the updated version of ZenML.

For more information, read about the device flow in our documentation.

Performance enhancements (#3207)

Internal API adjustments have reduced the footprint of ZenML API objects by up to 35%. This will particularly benefit users with large step and pipeline configurations. Further reductions will be implemented in our next release.

Model Control Plane debut (#5648)

ZenML now includes a preliminary version of the model control plane, a feature for registering models and their metadata on a single ZenML dashboard view. Future releases will provide more details. To test this early version, follow this example.

Breaking Changes

• Environment variables ZENML_AUTH_TYPE and ZENML_JWT_SECRET_KEY have been renamed to ZENML_SERVER_AUTH_SCHEME and ZENML_SERVER_JWT_SECRET_KEY, respectively.
• All ZenML server-issued JWT tokens now include an issuer and an audience. After the server update, current scheduled pipelines become invalidated. Reset your schedules and reconnect all clients to the server to obtain new tokens.
• UnmaterializedArtifact has been relocated to zenml.artifacts. Change your import statement from from zenml.materializers import UnmaterializedArtifact to from zenml.artifacts.unmaterialized_artifact import UnmaterializedArtifact.

Deprecations

• zenml.steps.external_artifact.ExternalArtifact has moved to zenml.artifacts.external_artifact.ExternalArtifact.
