-No option was added, removed or renamed, and no default changed (86 options). It is a patch because every saved setting still starts, as on 0.18.2.
+**A minor bump: changed behaviour (price trading), 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 0.18.2 also

 **Price trading skips periods that are over.** When the add-on trades on price, it now picks only from price periods that are still ahead. On 15-minute prices the battery therefore trades for longer (about 1.5 to 2.5 times the minutes in a simulation of 16 real days), so it cycles more. Hourly and day/night sites change too: they no longer pause at the start of each hour.
