v1.0.57

• Allow serde_json::Deserializer to be instantiated without consuming the serde_json::​de::Read impl (#684)

v1.0.56

• Improve compiler diagnostic on missing commas inside json! macro invocation (rust-lang/rust#73777)

v1.0.55

• Fix missing build script required for using float_roundtrip (https://github.com/serde-rs/json/releases/tag/v1.0.54)

v1.0.54

• Add float_roundtrip feature to enable a slower but higher precision float parser based on lexical.

  Enabling float_roundtrip will use sufficient precision when parsing fixed precision floats from JSON to ensure that they maintain accuracy when round-tripped through JSON. This comes at an approximately 2x performance cost for parsing floats compared to the default best-effort precision.

  Unlike arbitrary_precision, the new float_roundtrip feature makes f64 -> JSON -> f64 produce output identical to the input. arbitrary_precision is for making JSON -> serde_json::Number -> JSON produce output identical to the input.

  serde_json = { version = "1.0.54", features = ["float_roundtrip"] }

v1.0.53

• Add FusedIterator impls for StreamDeserializer and for Map's various iterators

v1.0.50

• Implement Eq for Value, Map, Number (#640, thanks @smarnach)

• Improve error message when neither "std" nor "alloc" feature is enabled (#643)

v1.0.48

• Add serde_json::value::Serializer which produces a Value as output (#621, thanks @sdleffler)
