   * Override charge current
   * Pass in current measurements (p1, battery, ...) - this eliminates having to use additionalhard
   * Switch between single- and three phase power (requires extra 2P relais on the 2nd output)
+* Added "Inverted Eastron" kWh, so that polarity is reversed when power is supplied to meter from below (like in most Dutch power panels)
+* Added current-limiting functionality if a subpanel is used, example:
+
+                             mains
+                               |
+                        [main breaker 25A]
+                               |
+                        [kWh meter "Mains"]
+                               |
+            -----------------------------------
+            |            |                    |
+                [group breaker 16A]   [subpanel breaker 16A]
+                                              |
+                                       [kWh meter "EV"]
+                                              |
+                                        ----------------
+                                        |              |
+                            [washer breaker 16A]  [smartevse breaker 16A]
+
+   In this example you configure Mains to 25A, MaxCircuit to 16A; the charger will limit itself so that neither the 25A mains nor the 16A from the subpanel will be exceeded...
+
+* Added wifi-debugging: if compiled in, you can debug SmartEVSE device by telnetting to it over your wifi connection
+* Small code optimisations, fixed some small bugs
