Changelog

All notable changes to this project are documented in this file.

THIS LIBRARY IS STILL IN ALPHA AND THERE ARE NO GUARANTEES REGARDING API STABILITY YET

v0.7.4 - 2022-03-21

⚠️ Starting from this version, Go 1.17+ is required to use this package.

v0.7.3 - 2021-11-02

  • Fix the encoding of zero-value time.Duration type in string format.

v0.7.2 - 2021-08-31

  • Minor performances improvements (remove inlined functions in appendEscapedBytes).

v0.7.1 - 2020-03-03

  • Fix a regression in the marshaling of nil map keys that implement the encoding.TextMarshaler interface, intoduced during refactor in version v0.5.0.
  • Split TestTextMarshalerMapKey and TestNilMarshaler tests with build constraints to allow previously ignored cases to run with Go1.14.

v0.7.0 - 2020-02-17

  • Add the omitnil field tag's option, which specifies that a field with a nil pointer should be omitted from the encoding. This option has precedence over the omitempty option. See this issue for more informations about the original proposal: #22480.

v0.6.0 - 2020-02-14

  • Add support for the sync.Map type. The marshaling behavior for this type is similar to the one of the Go map.

v0.5.0 - 2020-02-02

Refactor of the entire project.

This includes the following changes, but not limited to:

  • Remove the Encoder type to simplify the usage of the library and stick more closely to the design of encoding/json
  • Reduce the number of closures used. This improves readability of stacktraces and performance profiles.
  • Improve the marshaling performances of many types.
  • Add support for marshaling json.RawMessage values.
  • Add new options DenyList, NoNumberValidation, NoCompact, and rename some others.
  • Replace the Marshaler and MarshalerCtx interfaces by AppendMarshaler and AppendMarshalerCtx to follow the new append model. See this issue for more details: #34701.
  • Remove the IntegerBase option, which didn't worked properly with the string JSON tag.

Some of the improvements have been inspired by the github.com/segmentio/encoding project.

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.

v0.3.1 - 2019-10-09

  • Fix HTML characters escaping in struct field names.
  • Add examples for Marshal, MarshalTo and Encoder's Encode.
  • Refactor string encoding to be compliant with encoding/json.

v0.3.0 - 2019-09-23

  • Add global functions Marshal, MarshalTo and Register.
  • Update README.md: usage, examples and benchmarks.

v0.2.1 - 2019-09-10

  • Refactor instructions for types implementing the json.Marshaler and encoding.TextMarshaler interfaces.
    • Fix encoding of nil instances.
    • Fix behavior for pointer and non-pointer receivers, to comply with encoding/json.
  • Fix bug that prevents tagged fields to dominate untagged fields.
  • Add support for anonymous struct pointer fields.
  • Improve tests coverage of encoder.go.
  • Add test cases for unexported non-embedded struct fields.

v0.2.0 - 2019-09-01

  • Add support for json.Number.
  • Update README.md to add a Go1.12+ requirement notice.

v0.1.0 - 2019-08-30

Initial realease.
