222### Support context for MarshalJSON and UnmarshalJSON ( #248 )
223
224* json.MarshalContext(context.Context, interface{}, ...json.EncodeOption) ([]byte, error)
225* json.NewEncoder(io.Writer).EncodeContext(context.Context, interface{}, ...json.EncodeOption) error
226* json.UnmarshalContext(context.Context, []byte, interface{}, ...json.DecodeOption) error
227* json.NewDecoder(io.Reader).DecodeContext(context.Context, interface{}) error
228
229```go
230type MarshalerContext interface {
231 MarshalJSON(context.Context) ([]byte, error)
232}
233
234type UnmarshalerContext interface {
235 UnmarshalJSON(context.Context, []byte) error
236}
237```
238
239### Add DecodeFieldPriorityFirstWin option ( #242 )
240
241In the default behavior, go-json, like encoding/json, will reflect the result of the last evaluation when a field with the same name exists. I've added new options to allow you to change this behavior. `json.DecodeFieldPriorityFirstWin` option reflects the result of the first evaluation if a field with the same name exists. This behavior has a performance advantage as it allows the subsequent strings to be skipped if all fields have been evaluated.

371
372### Fix encoder
373
374- Fixed handling of MarshalJSON of function type
375
376### Fix decoding of slice of pointer type
377
378If there is a pointer value, go-json will use it. (This behavior is necessary to achieve the ability to prioritize pre-filled values). However, since slices are reused internally, there was a bug that referred to the previous pointer value. Therefore, it is not necessary to refer to the pointer value in advance for the slice element, so we explicitly initialize slice element by `nil`.
379
380# v0.4.8 - 2021/3/21
381
