 ## 0.13.0
 
-**A minor bump: new behaviour, a new settings page, and six new options.**
-No option was removed or renamed, and no default of an existing option
-changed (77 options -> 83). The live options blob on record passes this
-version's validator (`tools/predeploy_check.py`, offline).
+**A minor bump: new behaviour, a new add-on page (Home, Settings, Batteries,
+Setup), and six new options.** No option was removed or renamed, and no
+default of an existing option changed (77 options -> 83). The only new
+start-up checks are on the new options, so options that start 0.12.0 also
+start 0.13.0.
 
 New options, and what they do if you leave them alone:
 
 | option | default | left alone |
 |---|---|---|
-| `peak_margin_w` | `50` | the peak guard aims 50 W below your peak limit; set `0` for the old aim ([[SAFETY-79]]) |
+| `peak_margin_w` | `50` | the peak guard aims 50 W below your peak limit, or below a higher peak already reached this month; `0` is the old aim ([[SAFETY-79]]) |
 | `battery_modes_enabled` | `false` | no battery modes, control as before ([[OPT-11]]) |
 | `pv_forecast_entity`, `pv_forecast_tomorrow_entity` | empty | no solar forecast is used ([[OPT-11]]) |
 | `solar_trust_pct` | `70` | only used with a solar forecast ([[OPT-11]]) |
 | `pv_invert_entities` | `[]` | PV readings as before ([[TEL-14]]) |
 
-⚠️ **Turn on Watchdog** on the add-on's Info tab. If control stops, the
-add-on now sets the batteries to 0 W and exits; Home Assistant only starts it
-again when Watchdog is on ([[SAFETY-61]], [[DOC-5]]).
+⚠️ **Turn on Watchdog** on the add-on's Info tab. It is off by default. If
+the control loop crashes, the add-on now sets the batteries to 0 W and stops.
+Home Assistant only starts it again when Watchdog is on ([[SAFETY-61]],
+[[DOC-5]]).
+
+⚠️ **The peak guard now starts a little earlier.** It aims 50 W below your
+peak limit, so the batteries give a bit more at peak times. Set
+`peak_margin_w: 0` for the old aim ([[SAFETY-79]]).
