Changes¶ ↑

Unreleased¶ ↑

2025-05-23 (2.12.2)¶ ↑

• Fix compiler optimization level.

2025-05-23 (2.12.1)¶ ↑

• Fix a potential crash in large negative floating point number generation.

• Fix for JSON.pretty_generate to use passed state object’s generate instead of state class as the required parameters aren’t available.

2025-05-12 (2.12.0)¶ ↑

• Improve floating point generation to not use scientific notation as much.

• Include line and column in parser errors. 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 emited 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

• 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.

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.

• 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 include newline inside empty object and arrays.

2024-11-04 (2.7.6)¶ ↑

• Workaround different versions of json and json_pure being loaded (not officially supported).

• Make json_pure Ractor compatible.

2024-10-24 (2.7.3)¶ ↑

• There were still some mentions of dual GPL licensing in the source, but JSON has just the Ruby license that itself includes an explicit dual-licensing clause that allows covered software to be distributed under the terms of the Simplified BSD License instead for all ruby versions >= 1.9.3. This is however a GPL compatible license according to the Free Software Foundation. I changed these mentions to be consistent with the Ruby license setting in the gemspec files which were already correct now.

• There were still some mentions of dual GPL licensing in the source, but JSON has just the Ruby license that itself includes an explicit dual-licensing clause that allows covered software to be distributed under the terms of the Simplified BSD License instead for all ruby versions >= 1.9.3. This is however a GPL compatible license according to the Free Software Foundation. I changed these mentions to be consistent with the Ruby license setting in the gemspec files which were already correct now.

• Security fix for JSON create_additions default value and JSON::GenericObject. It should not be possible to create additions unless explicitly requested by setting the create_additions argument to true or using the JSON.load/dump interface. If JSON::GenericObject is supposed to be automatically deserialised, this has to be explicitly enabled by setting JSON::GenericObject.json_creatable = true as well.

• fast_generate now raises an exception for nan and infinite floats.

• On Ruby 1.8 json supports parsing of UTF-8, UTF-16BE, UTF-16LE, UTF-32BE, and UTF-32LE JSON documents now. Under Ruby 1.9 the M17n conversion functions are used to convert from all supported encodings. ASCII-8BIT encoded strings are handled like all strings under Ruby 1.8 were.

• Better documentation

2009-08-23 (1.1.9)¶ ↑

• Added forgotten main doc file extra_rdoc_files.

2009-08-23 (1.1.8)¶ ↑

• Applied patch by okkez_ in order to fix Ruby Bug #1768: redmine.ruby-lang.org/issues/show/1768.

• Finally got around to avoid the rather paranoid escaping of ?/ characters in the generator’s output. The parsers aren’t affected by this change. Thanks to Rich Apodaca rapodaca@metamolecular.com for the suggestion.

2009-06-29 (1.1.7)¶ ↑

• Security Fix for JSON::Pure::Parser. A specially designed string could cause catastrophic backtracking in one of the parser’s regular expressions in earlier 1.1.x versions. JSON::Ext::Parser isn’t affected by this issue. Thanks to Bartosz Blimke bartosz@new-bamboo.co.uk for reporting this problem.

• This release also uses a less strict ruby version requirement for the creation of the mswin32 native gem.

2009-05-10 (1.1.6)¶ ↑

• No changes. І tested native linux gems in the last release and they don’t play well with different ruby versions other than the one the gem was built with. This release is just to bump the version number in order to skip the native gem on rubyforge.

2009-05-10 (1.1.5)¶ ↑

• Started to build gems with rake-compiler gem.

• Applied patch object/array class patch from Brian Candler B.Candler@pobox.com and fixes.

2009-04-01 (1.1.4)¶ ↑

• Fixed a bug in the creation of serialized generic rails objects reported by Friedrich Graeter graeter@hydrixos.org.

• Deleted tests/runner.rb, we’re using testrb instead.

• Editor supports Infinity in numbers now.

• Made some changes in order to get the library to compile/run under Ruby 1.9.

• Improved speed of the code path for the fast_generate method in the pure variant.

2008-07-10 (1.1.3)¶ ↑

• Wesley Beary monki@geemus.com reported a bug in json/add/core’s DateTime handling: If the nominator and denominator of the offset were divisible by each other Ruby’s Rational#to_s returns them as an integer not a fraction with ‘/’. This caused a ZeroDivisionError during parsing.

• Use Date#start and DateTime#start instead of sg method, while remaining backwards compatible.

• Supports ragel >= 6.0 now.

• Corrected some tests.

• Some minor changes.

2007-11-27 (1.1.2)¶ ↑

• Remember default dir (last used directory) in editor.

• JSON::Editor.edit method added, the editor can now receive json texts from the clipboard via C-v.

• Load json texts from an URL pasted via middle button press.

• Added :create_additions option to Parser. This makes it possible to disable the creation of additions by force, in order to treat json texts as data while having additions loaded.

• Jacob Maine jmaine@blurb.com reported, that JSON(:foo) outputs a JSON object if the rails addition is enabled, which is wrong. It now outputs a JSON string “foo” instead, like suggested by Jacob Maine.

• Discovered a bug in the Ruby Bugs Tracker on rubyforge, that was reported by John Evans lgastako@gmail.com. He could produce a crash in the JSON generator by returning something other than a String instance from a to_json method. I now guard against this by doing a rather crude type check, which raises an exception instead of crashing.

2007-07-06 (1.1.1)¶ ↑

• Yui NARUSE naruse@airemix.com sent some patches to fix tests for Ruby 1.9. 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 <code></code> 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 ([ trn]), 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. Thanks for the report go to Florian Munz surf@theflow.de.

2005-09-23 (0.4.0)¶ ↑

• Initial Rubyforge Version
