Release· Databricks release notes (AWS)
Unity Catalog Python UDFs are GA for scalar and batch use
Scalar and batch Unity Catalog Python UDFs are now generally available on all supported compute types. The release adds named handlers for row-at-a-time scalar UDFs, removes the five-UDF-call-per-query limit, and aligns scalar TIMESTAMP inputs with PySpark behavior. Some capabilities require environment_version 6 or above, and requirements vary by feature and compute type.
Learners using Python UDFs need to know which capabilities are now GA and when an environment version setting is required.
