-CWL v1.1 introduces several features to the standard that were previously available as Arvados extensions. CWL v1.1 syntax is backwards compatible with v1.0, so you can just change @cwlVersion: v1.0@ to @cwlVersion: v1.1@ and update your script to using the standard features. On Arvados, there is only one behavior change between CWL v1.0 and v1.1 to be aware of: for performance reasons, Directory listings are no longer loaded by default. To control loading Directory listings, use "loadListing":https://www.commonwl.org/v1.1/CommandLineTool.html#CommandInputParameter or "LoadListingRequirement":https://www.commonwl.org/v1.1/CommandLineTool.html#LoadListingRequirement (the extension @cwltool:LoadListingRequirement@ is deprecated.)

-If a step requires network access, use "NetworkAccess":https://www.commonwl.org/v1.1/CommandLineTool.html#NetworkAccess instead of the Arvados-specific "arv:APIRequirement":cwl-extensions.html#APIRequirement .
