3.0.0

CHANGES:

2025-05-29

Changed

• Floats are now always output to JSON in a standard-conformant way or not at
  all (raising an exception). This makes the std variants of functions
  identical to the non-std variants and the std arguments have no effect.
  Users are encouraged to switch to the non-std affixed variants, the others
  will be deprecated in the future. (#184, @Leonidas-from-XIV)
• Bumped the minimum required version of OCaml for the main package to 4.08
  since the CI dropped the support. This however allows removing the dependency
  on the seq library, so the depencency cone becomes slightly smaller. (#194,
  @Leonidas-from-XIV)

Fixed

• Fixed handling of escape sequences in JSON5. Known escapes like \b will be
  properly unescaped and undefined escape sequences will unescape to the
  character itself as per spec (#187, @david-maison-TrustInSoft)
• Fixed tests failing on Windows due to disagreements with the length of an
  input channel and the text mode conversion (#192, @Leonidas-from-XIV)

Removed

• Removed support for Tuple and Variant in JSON. It was a non-standard
  extension that was rarely used, so this simplifies the Yojson types and the
  parser more standard-conforming (#105, #158, #185 @Leonidas-from-XIV)

2.2.2

CHANGES:

2024-06-27

Added

• Add locations in the JSON5 parser error messages (@gcluzel, #182)

2.2.1

CHANGES:

2024-06-04

Fixed

• Don't expose Yojson_five internals anymore (@Leonidas_from_XIV, #180)

2.2.0

CHANGES:

2024-05-31

Added

• Added support for JSON5 (@dhilst, @gorm-issuu, @gertsonderby, #152)

Removed

• Remove CPPO dependency to make the Yojson installation lighter
  (@Leonidas-from-XIV, #175)

2.1.2

CHANGES:

2023-11-23

Fixed

• Fix the error location reported in the exception. Regression in 2.1.1
  (reported by @johnridesabike, regression test by @ElectreAAS, fix by
  @Leonidas-from-XIV, #171, #172)

2.1.1

CHANGES:

2023-10-10

Changed

• Make Basic, Safe & Raw seperate compilation units that get exposed by
  the main module as suggested by @hhugo to enable JSOO to discard unused
  modules. No API changes should be observable. (#84, #167 @Leonidas-from-XIV)
• Removed forward refs in the parser to make dead-code elimination in JSOO
  better (#168, @hhugo)

2.1.0

CHANGES:

2023-04-26

Added

• Add Yojson.Raw.Util module to provide combinators for extracting fields
  from Yojson.Raw.t values. (@tmcgilchrist, #163)

• Add Util.path function to recurse into an object through a list of keys.
  (@cuihtlauac, @Leonidas-from-XIV, #157)

2.0.2

CHANGES:

2022-08-09

Added

• Expanded documentation of exceptions (@sim642, #148)

Removed

• Removed undocumented and unused functions write_float_fast and
  write_std_float_fast from Yojson, Yojson.Basic and Yojson.Safe
  (@sim642, #149)

Fixed

• Fix out-of-bounds error occurring when parsing object field names
  with atdgen parsers using map_ident or map_lexeme (@mjambon, #150)

2.0.1

CHANGES:

2022-06-28

Fixed

• Fix pretty-printing behavior for lists/objects inside lists (@c-cube
  #141, @mjambon #142)

2.0.0

CHANGES:

Removed

• Removed dependency on easy-format and removed pretty_format from
  Yojson, Yojson.Basic, Yojson.Safe and Yojson.Raw. (@c-cube, #90)
• Removed dependency on biniou, simplifying the chain of dependencies. This
  changes some APIs:
  • Bi_outbuf.t in signatures is replaced with Buffer.t
  • to_outbuf becomes to_buffer and stream_to_outbuf becomes
    stream_to_buffer
    (@Leonidas-from-XIV, #74, and @gasche, #132)
• Removed yojson-biniou library
• Removed deprecated json type aliasing type t which has been available
  since 1.6.0 (@Leonidas-from-XIV, #100).
• Removed json_max type (@Leonidas-from-XIV, #103)
• Removed constraint that the "root" value being rendered (via either
  pretty_print or to_string) must be an object or array. (@cemerick, #121)
• Removed validate_json as it only made sense if the type was called json.
  (@Leonidas-from-XIV, #137)

Add

• Add an opam package yojson-bench to deal with benchmarks dependency
  (@tmcgilchrist, #117)
• Add a benchmark to judge the respective performance of providing a buffer vs
  letting Yojson create an internal (#134, @Leonidas-from-XIV)
• Add an optional suf keyword argument was added to functions that write
  serialized JSON, thus allowing NDJSON output. Most functions default to not
  adding any suffix except for to_file (#124, @panglesd) and functions
  writing sequences of values where the default is \n (#135,
  @Leonidas-from-XIV)

Change

• The stream_from_* and stream_to_* functions now use a Seq.t instead of a
  Stream.t, and they are renamed into seq_from_* and seq_to_* (@gasche, #131).

Fix

• Avoid copying unnecessarily large amounts of strings when parsing (#85, #108,
  @Leonidas-from-XIV)
• Fix stream_to_file (#133, @tcoopman and @gasche)
