v1.0.61

• Add impl From<Number> for Value (#737, thanks @imp)

v1.0.60

• Add impl FromIterator<(impl Into<String>, impl Into<Value>)> for Value, which collects a Value::Object (#733, thanks @matklad)

v1.0.59

• In arbitrary_precision mode, return None from serde_json::Number::as_f64 if the JSON number is larger than the maximum possible f64

v1.0.58

• Add serde_json::Map::remove_entry, matching the equivalent API on BTreeMap

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

• Reduce unhelpful indentation in the {:#?} format of serde_json::Value
• Remove some unnecessary runtime checks from Serializer::collect_str

v1.0.52

• Add serde_json::value::to_raw_value to convert a serializable value to Box<RawValue> (#658, thanks @jplatte)
