 # Changelog
 
+## 0.17.0
+
+**A minor bump: changed behaviour, and no option changes.** No option was
+added, removed or renamed, and no default changed (83 options). Options you
+saved work as before. The changes below apply with one inverter or two, unless
+a line says "Two inverters".
+
+**Maintenance with no battery level.** This release changes how battery
+maintenance ends when the battery level is missing (MAINT-13, MAINT-14,
+MAINT-15). It now ends on its own time limits instead of waiting for the level
+to come back; you do not need to change any option.
+
+Contents of this release, in merge order since 0.16.0 (`451729c`):
+
+| | |
+|---|---|
+| `b527e99` | Two inverters: after a drain ends, the other battery no longer swings on old readings. In the test, it held steady for 23 s where 0.16.0 moved it by 720 W ([[SAFETY-103]]) |
+| `8a17711` | A full battery that stops at 98 or 99 % no longer counts as a failed charge. After 60 min with no new high, the charge counts as done; a charge that truly fails now waits 7 days and shows one notice ([[MAINT-13]]) |
+| `bf3ac79` | With no battery level, a maintenance charge still ends at its time limit and a drain waits at 0 W. The log no longer repeats a line every second ([[MAINT-14]]) |
+| `db9e231` | One inverter: when maintenance charges a battery that is already full, the log no longer repeats "The battery refuses to give power" every second. In the test, 1 line in 16 min where 0.16.0 wrote about 1,700; the power does not change ([[SAFETY-107]]) |
+| `580c200` | The balancing hold after a charge now ends on time when the battery level is missing. Before, it waited until the level came back ([[MAINT-15]]) |
+
+### Known issues
+
+- A false "Battery is not keeping up" can still show when the peak guard pauses a maintenance charge ([[SAFETY-92]]).
+- A battery capped at a low limit with a perfectly flat reading can still trip the stale check ([[SAFETY-74]]).
+- A battery whose reading at rest is beyond about ±170 W is still not caught when it refuses, as in 0.14.0 ([[SAFETY-97]]).
+- The peak guard can still back off near the end of a 15-minute period when a meter reading is late, by less than 30 s ([[SAFETY-99]]).
+- Two inverters: the maintenance charge can switch on and off while the house is above the peak aim ([[SAFETY-88]]).
+- Two inverters: the "circulating" figure counts a battery's reading at rest ([[SAFETY-98]]).
+- Two inverters: a drain that starts during a big step in house use can send the other battery to full power, and about 1 kW goes to the grid for about 10 s ([[SAFETY-104]]).
+- Two inverters: when a battery comes back during a maintenance charge, the grid can step by several kW at once ([[SAFETY-101]]).
+- Two inverters: when a battery drops out during a solar surplus, the others can swing by up to 1.5 kW ([[SAFETY-105]]).
+- Two inverters: after a drain ends, a change in house use can go unanswered for about 9 s, because some readings are old ([[SAFETY-106]]).
+- Two inverters: when one battery's level is missing, both batteries are held at 0 W, and for the first 15 s the last command stays on ([[SAFETY-108]]).
+- Two inverters: if one battery's level stays missing for 12 h, the other battery's cycle can be marked failed, with a 7-day wait and a notice, though it is healthy ([[MAINT-17]]).
+- One inverter: after a link drop, the battery's own safety stop to 0 W can be taken as a refusal, and the site stays at 0 W for up to 15 min ([[SAFETY-102]]).
+
+### If you are crossing from a version older than 0.10.0
+
+`## 0.10.0` below can refuse an old config: `slew_w` above its limit, and the
+withdrawn `price_provider` ids `engie_dynamic`, `totalenergies_dynamic` and
+`eneco_eddy`. Read it before you update. Run `tools/predeploy_check.py` with the
+bare options (`jq '.data.options'`) first.
