+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@).

 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.
