+
+- Back up first (`sudo jarld backup`).
+- When jarld first starts, it rewrites named's configuration: options
+  move into their new fixed order, and every view gets its view key in
+  `match-clients` and `keys.conf`. It is checked with named-checkconf
+  before named reloads, like any apply. Files you changed by hand are left
+  alone; the log then says to run `jarl resync`.
+- The systemd unit changed (it allows `AF_NETLINK`). The package replaces
+  it; an override that adds `AF_NETLINK` (`systemctl edit jarl`) does no
+  harm and can be removed.
+- The database moves to schema 7 (disabled zones) as jarld starts.
+- If statistics showed a spike after views were created or changed, see
+  "Statistics" under Fixed: the bad minutes can be removed from
+  `/var/lib/jarl/stats.db` (minute rows have `res = 'm'`; the hours and
+  days that include them are `'h'` and `'d'`).
