+This is breaking change for users creating and running pipeline programmatically. The `createPipeline`
+function exported by the package now requires that an RDF/JS Environment is passed as an argument. 
+A compatible environment which includes all necessary factories can be imported from the new 
+`barnard59-env` package.

+Removed dependency on any RDF/JS Environment. The CLI provides it at runtime to ensure that steps
+use the same factories. Step implementors are encouraged to use the environment provided by the
+barnard59 runtime insead of importing directly.
