Note that `JSON.load` remains with default `true` and is meant for internal serialization of trusted data. [CVE-2020-10663] * Fix passing args all #to_json in json/add/*. * Fix encoding issues * Fix issues of keyword vs positional parameter * Fix JSON::Parser against bigdecimal updates * Bug fixes to JRuby port ## 2019-02-21 (2.2.0) * Adds support for 2.6 BigDecimal and ruby standard library Set datetype. ## 2017-04-18 (2.1.0) * Allow passing of `decimal_class` option to specify a class as which to parse JSON float numbers. ## 2017-03-23 (2.0.4) * Raise exception for incomplete unicode surrogates/character escape sequences. This problem was reported by Daniel Gollahon (dgollahon). * Fix arbitrary heap exposure problem. This problem was reported by Ahmad Sherif (ahmadsherif). ## 2017-01-12 (2.0.3) * Set `required_ruby_version` to 1.9 * Some small fixes ## 2016-07-26 (2.0.2) * Specify `required_ruby_version` for json\_pure. * Fix issue #295 failure when parsing frozen strings. ## 2016-07-01 (2.0.1) * Fix problem when requiring json\_pure and Parser constant was defined top level. * Add `RB_GC_GUARD` to avoid possible GC problem via Pete Johns. * Store `current_nesting` on stack by Aaron Patterson. ## 2015-09-11 (2.0.0) * Now complies to newest JSON RFC 7159. * Implements compatibility to ruby 2.4 integer unification. * Drops support for old rubies whose life has ended, that is rubies < 2.0. Also see https://www.ruby-lang.org/en/news/2014/07/01/eol-for-1-8-7-and-1-9-2/ * 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. ## 2017-01-13 (1.8.6) * Be compatible with ancient ruby 1.8 (maybe?) ## 2015-09-11 (1.8.5) * Be compatible with ruby 2.4.0 * 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. ## 2015-06-01 (1.8.3) * Fix potential memory leak, thx to nobu. ## 2015-01-08 (1.8.2) * Some performance improvements by Vipul A M . * Fix by Jason R. Clark to avoid mutation of `JSON.dump_default_options`. * More tests by Michael Mac-Vicar and fixing `space_before` accessor in generator. * Performance on Jruby improved by Ben Browning . * Some fixes to be compatible with the new Ruby 2.2 by Zachary Scott and SHIBATA Hiroshi . ## 2013-05-13 (1.8.1) * Remove Rubinius exception since transcoding should be working now. ## 2013-05-13 (1.8.0) * Fix https://github.com/flori/json/issues/162 reported by Marc-Andre Lafortune . Thanks! * Applied patches by Yui NARUSE to suppress warning with -Wchar-subscripts and better validate UTF-8 strings. * Applied patch by ginriki@github to remove unnecessary if. * Add load/dump interface to `JSON::GenericObject` to make serialize :some_attribute, `JSON::GenericObject` work in Rails active models for convenient `SomeModel#some_attribute.foo.bar` access to serialised JSON data. ## 2013-02-04 (1.7.7) * 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. * Remove useless assert in fbuffer implementation. * Apply patch attached to https://github.com/flori/json/issues#issue/155 provided by John Shahid , Thx! * Add license information to rubygems spec data, reported by Jordi Massaguer Pla . * Improve documentation, thx to Zachary Scott . ## 2012-11-29 (1.7.6) * Add `GeneratorState#merge` alias for JRuby, fix state accessor methods. Thx to jvshahid@github. * Increase hash likeness of state objects. ## 2012-08-17 (1.7.5) * Fix compilation of extension on older rubies. ## 2012-07-26 (1.7.4) * Fix compilation problem on AIX, see https://github.com/flori/json/issues/142 ## 2012-05-12 (1.7.3) * Work around Rubinius encoding issues using iconv for conversion instead. ## 2012-05-11 (1.7.2) * Fix some encoding issues, that cause problems for the pure and the extension variant in jruby 1.9 mode. ## 2012-04-28 (1.7.1) * Some small fixes for building ## 2012-04-28 (1.7.0) * Add `JSON::GenericObject` for method access to objects transmitted via JSON. ## 2012-04-27 (1.6.7) * Fix possible crash when trying to parse nil value. ## 2012-02-11 (1.6.6) * Propagate src encoding to values made from it (fixes 1.9 mode converting everything to ascii-8bit; harmless for 1.8 mode too) (Thomas E. Enebo ), should fix https://github.com/flori/json/issues#issue/119. * Fix https://github.com/flori/json/issues#issue/124 Thx to Jason Hutchens. * Fix https://github.com/flori/json/issues#issue/117 ## 2012-01-15 (1.6.5) * Vit Ondruch reported a bug that shows up when using optimisation under GCC 4.7. Thx to him, Bohuslav Kabrda and Yui NARUSE for debugging and developing a patch fix. ## 2011-12-24 (1.6.4) * Patches that improve speed on JRuby contributed by Charles Oliver Nutter . * Support `object_class`/`array_class` with duck typed hash/array. ## 2011-12-01 (1.6.3) * Let `JSON.load('')` return nil as well to make mysql text columns (default to `''`) work better for serialization. ## 2011-11-21 (1.6.2) * Add support for OpenStruct and BigDecimal. * Fix bug when parsing nil in `quirks_mode`. * Make JSON.dump and JSON.load methods better cooperate with Rails' serialize method. Just use: serialize :value, JSON * Fix bug with time serialization concerning nanoseconds. Thanks for the patch go to Josh Partlow (jpartlow@github). * Improve parsing speed for JSON numbers (integers and floats) in a similar way to what Evan Phoenix suggested in: https://github.com/flori/json/pull/103 ## 2011-09-18 (1.6.1) * Using -target 1.5 to force Java bits to compile with 1.5. ## 2011-09-12 (1.6.0) * Extract utilities (prettifier and GUI-editor) in its own gem json-utils. * Split json/add/core into different files for classes to be serialised. ## 2011-08-31 (1.5.4) * Fix memory leak when used from multiple JRuby. (Patch by jfirebaugh@github). * Apply patch by Eric Wong that fixes garbage collection problem reported in https://github.com/flori/json/issues/46. * Add :quirks_mode option to parser and generator. * Add support for Rational and Complex number additions via json/add/complex and json/add/rational requires. ## 2011-06-20 (1.5.3) * Alias State#configure method as State#merge to increase duck type synonymy with Hash. * Add `as_json` methods in json/add/core, so rails can create its json objects the new way. ## 2011-05-11 (1.5.2) * Apply documentation patch by Cory Monty . * Add gemspecs for json and json\_pure. * Fix bug in jruby pretty printing. * Fix bug in `object_class` and `array_class` when inheriting from Hash or Array. ## 2011-01-24 (1.5.1) * Made rake-compiler build a fat binary gem. This should fix issue https://github.com/flori/json/issues#issue/54. ## 2011-01-22 (1.5.0) * Included Java source codes for the Jruby extension made by Daniel Luz . * Output full exception message of `deep_const_get` to aid debugging. * Fixed an issue with ruby 1.9 `Module#const_defined?` method, that was reported by Riley Goodside. ## 2010-08-09 (1.4.6) * Fixed oversight reported in http://github.com/flori/json/issues/closed#issue/23, always create a new object from the state prototype. * Made pure and ext api more similar again. ## 2010-08-07 (1.4.5) * Manage data structure nesting depth in state object during generation. This should reduce problems with `to_json` method definіtions that only have one argument. * Some fixes in the state objects and additional tests. ## 2010-08-06 (1.4.4) * Fixes build problem for rubinius under OS X, http://github.com/flori/json/issues/closed#issue/25 * Fixes crashes described in http://github.com/flori/json/issues/closed#issue/21 and http://github.com/flori/json/issues/closed#issue/23 ## 2010-05-05 (1.4.3) * Fixed some test assertions, from Ruby r27587 and r27590, patch by nobu. * Fixed issue http://github.com/flori/json/issues/#issue/20 reported by electronicwhisper@github. Thx! ## 2010-04-26 (1.4.2) * Applied patch from naruse Yui NARUSE to make building with Microsoft Visual C possible again. * Applied patch from devrandom in order to allow building of json_pure if extensiontask is not present. * Thanks to Dustin Schneider , who reported a memory leak, which is fixed in this release. * Applied 993f261ccb8f911d2ae57e9db48ec7acd0187283 patch from josh@github. ## 2010-04-25 (1.4.1) * Fix for a bug reported by Dan DeLeo , caused by T_FIXNUM being different on 32bit/64bit architectures. ## 2010-04-23 (1.4.0) * Major speed improvements and building with simplified directory/file-structure. * Extension should at least be compatible with MRI, YARV and Rubinius. ## 2010-04-07 (1.2.4) * Triger const_missing callback to make Rails' dynamic class loading work. ## 2010-03-11 (1.2.3) * Added a `State#[]` method which returns an attribute's value in order to increase duck type compatibility to Hash. ## 2010-02-27 (1.2.2) * Made some changes to make the building of the parser/generator compatible to Rubinius. ## 2009-11-25 (1.2.1) * Added `:symbolize_names` option to Parser, which returns symbols instead of strings in object names/keys. ## 2009-10-01 (1.2.0) * `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 a patch by OZAWA Sakuro to make json/pure work in environments that don't provide iconv. * Applied patch by okkez_ in order to fix Ruby Bug #1768: http://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 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 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 and fixes. ## 2009-04-01 (1.1.4) * Fixed a bug in the creation of serialized generic rails objects reported by Friedrich Graeter . * 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 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 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 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 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 . * 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 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 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 , thanks a bunch! ## 2006-08-25 (0.4.2) * Fixed a bug in handling solidi (/-characters), that was reported by Kevin Gilpin . ## 2006-02-06 (0.4.1) * Fixed a bug related to escaping with backslashes. Thanks for the report go to Florian Munz . ## 2005-09-23 (0.4.0) * Initial Rubyforge Version
