+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@.

+h3. Default result order changed
+
+When requesting a list of objects without an explicit @order@ parameter, the default order has changed from @modified_at desc, uuid asc@ to @modified_at desc, uuid desc@.  This means that if two objects have identical @modified_at@ timestamps, the tiebreaker will now be based on @uuid@ in decending order where previously it would be ascending order. The practical effect of this should be minor; with microsecond precision it is unusual to have two records with exactly the same timestamp, and order-sensitive queries should already provide an explicit @order@ parameter.

 h3. Ubuntu 18.04 Arvados Python packages now depend on python-3.8
 
 Ubuntu 18.04 ships with Python 3.6 as the default version of Python 3. Ubuntu also ships a version of Python 3.8, and the Arvados Python packages (@python3-arvados-cwl-runner@, @python3-arvados-fuse@, @python3-arvados-python-client@, @python3-arvados-user-activity@ and @python3-crunchstat-summary@) now depend on the @python-3.8@ system package.
