+h3. Now recommending Singularity 3.9.9
+
+The compute image "build script":{{site.baseurl}}/install/crunch2-cloud/install-compute-node.html now installs Singularity 3.9.9 instead of 3.7.4. The newer version includes a bugfix that should resolve "intermittent loopback device errors":https://dev.arvados.org/issues/18489 when running containers.
+
+h3. Changes to @arvados-cwl-runner --create-workflow@ and @--update-workflow@
+
+When using @arvados-cwl-runner --create-workflow@ or @--update-workflow@, by default it will now make a copy of all collection and Docker image dependencies in the target project.  Running workflows retains the old behavior (use the dependencies wherever they are found).  The can be controlled explicit with @--copy-deps@ and @--no-copy-deps@.
