+It is recommended to regenerate the table statistics for Postgres after upgrading to v1.2.0. If autovacuum is enabled on your installation, this script would do the trick:
+
+<pre>
+#!/bin/bash
+
+set -e
+set -u
+
+tables=`echo "\dt" | psql arvados_production | grep public|awk -e '{print $3}'`
+
+for t in $tables; do
+ echo "echo 'analyze $t' | psql arvados_production"
+ time echo "analyze $t" | psql arvados_production
+done
+</pre>
+
+If you also need to do the vacuum, you could adapt the script to run 'vacuum analyze' instead of 'analyze'.
+
+h4. New component: arvados-controller
+
+Commit "db5107dca":https://dev.arvados.org/projects/arvados/repository/revisions/db5107dca adds a new system service, arvados-controller. More detail is available in story "#13496":https://dev.arvados.org/issues/13497.
+
+To add the Arvados Controller to your system please refer to the "installation instructions":../install/install-controller.html after upgrading your system to 1.2.0.
+
+Verify your setup by confirming that API calls appear in the controller's logs (_e.g._, @journalctl -fu arvados-controller@) while loading a workbench page.
