Oct 7, 2026 · Release
MLflow 3.17.0 released with fine-grained permissions and TypeSafe judge support
On October 7, 2026 the MLflow project published version 3.17.0 on GitHub. The release notes list "Jev Decisions Across Evaluation, Gateway, and Tracing", which lets TypeSafe models be used in built-in scorers and custom judges, and "Fine-Grained Permissions for Shared Resources", with wildcard grants and explicit DENY for contained resource types such as runs, traces, and versions. They also describe opt-in daily summaries for trace analytics. The notes say SQL-backed servers need a coordinated mlflow db upgrade with all writers stopped, and that mixed-version rolling upgrades are not supported. USASI has not tested these changes.
