Hello @sdruskat ; Please don’t increment the cwlVersion manually, but use the cwl-upgrader instead. And if you aren’t adding anything to your description that needs a newer CWL version, then you don’t have to increment the version number to match other files. Mixing CWL versions is supported.
In your case, running cwl-upgrader will add the missing networkAccess: true
BTW, if you need a remote file available over HTTP(S) then it is often better to put the URL directly in the location field of your input object, as many CWL-aware workflow platforms will cache that file on repeated runs
Finally, you can see the full changelog for CWL v1.1 at Common Workflow Language (CWL) Command Line Tool Description, v1.1
