+   * Completely reworked privdata storage. There is now a single file,
+     and each host is sent only the privdata that its Properties actually use.
+     To transition existing privdata, run propellor against a host and
+     watch out for the red failure messages, and run the suggested commands
+     to store the privdata using the new storage scheme. You may find
+     it useful to run the old version of propellor to extract data from the old
+     privdata files during this migration.
+     Several properties that use privdata now require a context to be
+     specified. If in doubt, you can use anyContext, or
+     Context "hostname.example.com"
+   * Add --edit to edit a privdata value in $EDITOR.
+   * Add --list-fields to list all currently set privdata fields, along with
+     the hosts that use them.
+   * Fix randomHostKeys property to run openssh-server's postinst in a
+     non-failing way.
+   * Hostname.sane now cleans up the 127.0.0.1 localhost line in /etc/hosts,
+     to avoid eg, apache complaining "Could not reliably determine the
+     server's fully qualified domain name"."""]]
