 - The night grid charge no longer raises "Battery stopped limiting the peak" when the 15-minute period stays on the aim. A steadily rising load now alarms a little later, and with a peak margin of 0 a period can end up to 10 W over the limit without this alarm ([[SAFETY-126]]).
 - A night grid charge for *Leftover solar* no longer stops at 03:00 when the solar forecast sensors went quiet in the evening. The evening's figure is used until 06:00, and a charge that has started goes on to its level ([[OPT-34]]).
 
-**A patch bump: one fix for charging from the grid under the peak limit, and no option changes.**
+**A patch bump: two fixes, one for charging from the grid under the peak limit and one for the night charge of Leftover solar, and no option changes.**
 No option was added, removed or renamed, and no default changed (86 options).
 **Existing installs need no option change:** options that start 0.19.1 also
 start 0.19.2. The change below applies with one inverter or two.
