+
+h3. Slurm dispatcher requires configuration update
+
+If you use the Slurm dispatcher (@crunch-dispatch-slurm@) you must add a @Services.DispatchSLURM.InternalURLs@ section to your configuration file, as shown on the "updated install page":{{site.baseurl}}/install/crunch2-slurm/install-dispatch.html.
+
+h3. New proxy parameters for arvados-controller
+
+We now recommend disabling nginx proxy caching for arvados-controller, to avoid truncation of large responses.
+
+In your Nginx configuration file (@/etc/nginx/conf.d/arvados-api-and-controller.conf@), add the following lines to the @location /@ block with @http://controller@ (see "Update nginx configuration":{{site.baseurl}}/install/install-api-server.html#update-nginx for an example) and reload/restart Nginx (@sudo nginx -s reload@).
+
+<pre>
+    proxy_max_temp_file_size 0;
+    proxy_request_buffering  off;
+    proxy_buffering          off;
+    proxy_http_version       1.1;
+</pre>
+
+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@.
