CWL Upgrader

cwl-upgrader is a Python library and command-line tool designed to upgrade Common Workflow Language (CWL) documents. It supports upgrading CWL tools and workflows from older versions (draft-3, v1.0, v1.1) to the current v1.2 specification. The library focuses solely on syntax migration and does not perform validation of the document's correctness. It is actively maintained with frequent patch releases, often driven by dependency updates and Python version support.
