Both in the message and as exception attributes. +* Handle non-string hash keys with broken `to_s` implementations. +* `JSON.generate` now uses SSE2 (x86) or NEON (arm64) instructions when available to escape strings. + +### 2025-04-25 (2.11.3) + +* Fix a regression in `JSON.pretty_generate` that could cause indentation to be off once some `#to_json` has been called. + +### 2025-04-24 (2.11.2) + +* Add back `JSON::PRETTY_STATE_PROTOTYPE`. This constant was private API but is used by popular gems like `multi_json`. + It now emits a deprecation warning. + +### 2025-04-24 (2.11.1) + +* Add back `JSON.restore`, `JSON.unparse`, `JSON.fast_unparse` and `JSON.pretty_unparse`. + These were deprecated 16 years ago, but never emitted warnings, only undocumented, so are + still used by a few gems. + +### 2025-04-24 (2.11.0) + +* Optimize Integer generation to be ~1.8x faster. +* Optimize Float generation to be ~10x faster. +* Fix `JSON.load` proc argument to substitute the parsed object with the return value. + This better match `Marshal.load` behavior. +* Deprecate `JSON.fast_generate` (it's not any faster, so pointless). +* Deprecate `JSON.load_default_options`. +* Deprecate `JSON.unsafe_load_default_options`. +* Deprecate `JSON.dump_default_options`. +* Deprecate `Kernel#j` +* Deprecate `Kernel#jj` +* Remove outdated `JSON.iconv`. +* Remove `Class#json_creatable?` monkey patch. +* Remove deprecated `JSON.restore` method. +* Remove deprecated `JSON.unparse` method. +* Remove deprecated `JSON.fast_unparse` method. +* Remove deprecated `JSON.pretty_unparse` method. +* Remove deprecated `JSON::UnparserError` constant. +* Remove outdated `JSON::MissingUnicodeSupport` constant. + +### 2025-03-12 (2.10.2) + +* Fix a potential crash in the C extension parser. +* Raise a ParserError on all incomplete unicode escape sequence. This was the behavior until `2.10.0` inadvertently changed it. +* Ensure document snippets that are included in parser errors don't include truncated multibyte characters. +* Ensure parser error snippets are valid UTF-8. +* Fix `JSON::GeneratorError#detailed_message` on Ruby < 3.2 + +### 2025-02-10 (2.10.1) + +* Fix a compatibility issue with `MultiJson.dump(obj, pretty: true)`: `no implicit conversion of false into Proc (TypeError)`. + +### 2025-02-10 (2.10.0) + +* `strict: true` now accept symbols as values. Previously they'd only be accepted as hash keys. +* The C extension Parser has been entirely reimplemented from scratch. +* Introduced `JSON::Coder` as a new API allowing to customize how non native types are serialized in a non-global way. +* Introduced `JSON::Fragment` to allow assembling cached fragments in a safe way. +* The Java implementation of the generator received many optimizations. + +### 2024-12-18 (2.9.1) + +* Fix support for Solaris 10. + +### 2024-12-03 (2.9.0) + +* Fix C implementation of `script_safe` escaping to not confuse some other 3 wide characters with `\u2028` and `\u2029`. + e.g. `JSON.generate(["倩", "瀨"], script_safe: true)` would generate the wrong JSON. +* `JSON.dump(object, some_io)` now write into the IO in chunks while previously it would buffer the entire JSON before writing. +* `JSON::GeneratorError` now has a `#invalid_object` attribute, making it easier to understand why an object tree cannot be serialized. +* Numerous improvements to the JRuby extension. + +### 2024-11-14 (2.8.2) + +* `JSON.load_file` explicitly read the file as UTF-8. + +### 2024-11-06 (2.8.1) + +* Fix the java packages to include the extension. + +### 2024-11-06 (2.8.0) + +* Emit a deprecation warning when `JSON.load` create custom types without the `create_additions` option being explicitly enabled. + * Prefer to use `JSON.unsafe_load(string)` or `JSON.load(string, create_additions: true)`. +* Emit a deprecation warning when serializing valid UTF-8 strings encoded in `ASCII_8BIT` aka `BINARY`. +* Bump required Ruby version to 2.7. +* Add support for optionally parsing trailing commas, via `allow_trailing_comma: true`, which in cunjunction with the + pre-existing support for comments, make it suitable to parse `jsonc` documents. +* Many performance improvements to `JSON.parse` and `JSON.load`, up to `1.7x` faster on real world documents. +* Some minor performance improvements to `JSON.dump` and `JSON.generate`. +* `JSON.pretty_generate` no longer includes newlines inside empty object and arrays. + +### 2024-11-04 (2.7.6) + +* Fix a regression in JSON.generate when dealing with Hash keys that are string subclasses, call `to_json` on them. + +### 2024-10-25 (2.7.5) + +* Fix a memory leak when `#to_json` methods raise an exception. +* Gracefully handle formatting configs being set to `nil` instead of `""`. +* Workaround another issue caused by conflicting versions of both `json_pure` and `json` being loaded. + +### 2024-10-25 (2.7.4) + +* Workaround a bug in 3.4.8 and older https://github.com/rubygems/rubygems/pull/6490. + This bug would cause some gems with native extension to fail during compilation. +* Workaround different versions of `json` and `json_pure` being loaded (not officially supported). +* Make `json_pure` Ractor compatible. + +### 2024-10-24 (2.7.3) + +* Numerous performance optimizations in `JSON.generate` and `JSON.dump` (up to 2 times faster). +* Limit the size of ParserError exception messages, only include up to 32 bytes of the unparsable source. +* Fix json-pure's `Object#to_json` to accept non-state arguments. +* Fix multiline comment support in `json-pure`. +* Fix `JSON.parse` to no longer mutate the argument encoding when passed an ASCII-8BIT string. +* Fix `String#to_json` to raise on invalid encoding in `json-pure`. +* Delete code that was based on CVTUTF. +* Use the pure-Ruby generator on TruffleRuby. +* Fix `strict` mode in `json-pure` to not break on Integer. + +### 2024-04-04 (2.7.2) + +* Use rb_sym2str instead of

I applied them and adapted some of them a bit to run both on 1.8 and + 1.9. + * Introduced a `JSON.parse!` method without depth checking for people who + like danger. + * Made generate and `pretty_generate` methods configurable by an options hash. + * Added :allow_nan option to parser and generator in order to handle NaN, + Infinity, and -Infinity correctly - if requested. Floats, which aren't numbers, + aren't valid JSON according to RFC4627, so by default an exception will be + raised if any of these symbols are encountered. Thanks to Andrea Censi + <andrea.censi@dis.uniroma1.it> for his hint about this. + * Fixed some more tests for Ruby 1.9. + * Implemented dump/load interface of Marshal as suggested in ruby-core:11405 + by murphy <murphy@rubychan.de>. + * Implemented the `max_nesting` feature for generate methods, too. + * Added some implementations for ruby core's custom objects for + serialisation/deserialisation purposes. + +## 2007-05-21 (1.1.0) + * Implemented max_nesting feature for parser to avoid stack overflows for + data from untrusted sources. If you trust the source, you can disable it + with the option max_nesting => false. + * Piers Cawley <pdcawley@bofh.org.uk> reported a bug, that not every + character can be escaped by `\` as required by RFC4627. There's a + contradiction between David Crockford's JSON checker test vectors (in + tests/fixtures) and RFC4627, though. I decided to stick to the RFC, because + the JSON checker seems to be a bit older than the RFC. + * Extended license to Ruby License, which includes the GPL. + * Added keyboard shortcuts, and 'Open location' menu item to edit_json.rb. + +## 2007-05-09 (1.0.4) + * Applied a patch from Yui NARUSE <naruse@airemix.com> to make JSON compile + under Ruby 1.9. Thank you very much for mailing it to me! + * Made binary variants of JSON fail early, instead of falling back to the + pure version. This should avoid overshadowing of eventual problems while + loading of the binary. + +## 2007-03-24 (1.0.3) + * Improved performance of pure variant a bit. + * The ext variant of this release supports the mswin32 platform. Ugh! + +## 2007-03-24 (1.0.2) + * Ext Parser didn't parse 0e0 correctly into 0.0: Fixed! + +## 2007-03-24 (1.0.1) + * Forgot some object files in the build dir. I really like that - not! + +## 2007-03-24 (1.0.0) + * Added C implementations for the JSON generator and a ragel based JSON + parser in C. + * Much more tests, especially fixtures from json.org. + * Further improved conformance to RFC4627. + +## 2007-02-09 (0.4.3) + * Conform more to RFC4627 for JSON: This means JSON strings + now always must contain exactly one object `"{ ... }"` or array `"[ ... ]"` in + order to be parsed without raising an exception. The definition of what + constitutes a whitespace is narrower in JSON than in Ruby ([ \t\r\n]), and + there are differences in floats and integers (no octals or hexadecimals) as + well. + * Added aliases generate and `pretty_generate` of unparse and `pretty_unparse`. + * Fixed a test case. + * Catch an `Iconv::InvalidEncoding` exception, that seems to occur on some Sun + boxes with SunOS 5.8, if iconv doesn't support utf16 conversions. This was + reported by Andrew R Jackson <andrewj@bcm.tmc.edu>, thanks a bunch! + +## 2006-08-25 (0.4.2) + * Fixed a bug in handling solidi (/-characters), that was reported by + Kevin Gilpin <kevin.gilpin@alum.mit.edu>. + +## 2006-02-06 (0.4.1) + * Fixed a bug related to escaping with backslashes.

The reason for this is, that JSON doesn't support ranges +or arbitrary classes. In this case the json library falls back to call +`Object#to_json`, which is the same as `#to_s.to_json`. + +It's possible to add JSON support serialization to arbitrary classes by +simply implementing a more specialized version of the `#to_json method`, that +should return a JSON object (a hash converted to JSON with `#to_json`) like +this (don't forget the `*a` for all the arguments): + +```ruby +class Range + def to_json(*a) + { + 'json_class' => self.class.name, # = 'Range' + 'data' => [ first, last, exclude_end? ] + }.to_json(*a) + end +end +``` + +The hash key `json_class` is the class, that will be asked to deserialise the +JSON representation later. In this case it's `Range`, but any namespace of +the form `A::B` or `::A::B` will do. All other keys are arbitrary and can be +used to store the necessary data to configure the object to be deserialised. + +If the key `json_class` is found in a JSON object, the JSON parser checks +if the given class responds to the `json_create` class method. If so, it is +called with the JSON object converted to a Ruby hash. So a range can +be deserialised by implementing `Range.json_create` like this: + +```ruby +class Range + def self.json_create(o) + new(*o['data']) + end +end +``` + +Now it possible to serialise/deserialise ranges as well: + +```ruby +json = JSON.generate [1, 2, {"a"=>3.141}, false, true, nil, 4..10] +# => "[1,2,{\"a\":3.141},false,true,null,{\"json_class\":\"Range\",\"data\":[4,10,false]}]" +JSON.parse json +# => [1, 2, {"a"=>3.141}, false, true, nil, 4..10] +json = JSON.generate [1, 2, {"a"=>3.141}, false, true, nil, 4..10] +# => "[1,2,{\"a\":3.141},false,true,null,{\"json_class\":\"Range\",\"data\":[4,10,false]}]" +JSON.unsafe_load json +# => [1, 2, {"a"=>3.141}, false, true, nil, 4..10] +``` + +`JSON.generate` always creates the shortest possible string representation of a +ruby data structure in one line. This is good for data storage or network +protocols, but not so good for humans to read. Fortunately there's also +`JSON.pretty_generate` (or `JSON.pretty_generate`) that creates a more readable +output: + +```ruby + puts JSON.pretty_generate([1, 2, {"a"=>3.141}, false, true, nil, 4..10]) + [ + 1, + 2, + { + "a": 3.141 + }, + false, + true, + null, + { + "json_class": "Range", + "data": [ + 4, + 10, + false + ] + } + ] +``` + +There are also the methods `Kernel#j` for generate, and `Kernel#jj` for +`pretty_generate` output to the console, that work analogous to Core Ruby's `p` and +the `pp` library's `pp` methods. + +## Security + +When parsing or serializing untrusted input, parser and generator options should never be user controlled. + +```ruby +# Dangerous, DO NOT DO THIS. +JSON.generate(params[:data], params[:options]) +``` + +Security vulnerability reports relying on attacker controlled parsing or generator options will be handled as regular bug fixes. + +## Development + +### Prerequisites + +1.
