+### Fixed
+- ESPHome's compile-time warnings about "GPIO<x> is a Strapping PIN and should
+  be avoided" are now being suppressed. These warning are often interpreted
+  by users of this firmware as problems. However, the pinouts are dictated by
+  the hardware and there are no strapping issues because of how they are used.
