+## [v0.4.1] - 2019-10-23
+- Fix unsafe misuses reported by go vet and the new `-d=checkptr` cmd/compile flag introduced in the Go1.14 development tree by Matthew Dempsky. The issues were mostly related to invalid arithmetic operations and dereferences.
+- Fix map key types precedence order during marshaling. Keys of any string type are used directly instead of the `MarshalText` method, if the types also implement the `encoding.TextMarshaler` interface.
+
 ## [v0.4.0] - 2019-10-18
 - Add the `Marshaler` interface. Types that implements it can write a JSON representation of themselves to a `Writer` directly, to avoid having to allocate a buffer as they would usually do when using the `json.Marshaler` interface.
