-## 2019-12-11 (2.3.0)
- * Fix default of `create_additions` to always be `false` for `JSON(user_input)`
-   and `JSON.parse(user_input, nil)`.
-   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/*.

-
-## 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)

-  * 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.
-
-## 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 <vipulnsward@gmail.com>.
-  * Fix by Jason R. Clark <jclark@newrelic.com> to avoid mutation of
-    `JSON.dump_default_options`.
-  * More tests by Michael Mac-Vicar <mmacvicar@gmail.com> and fixing
-    `space_before` accessor in generator.
-  * Performance on Jruby improved by Ben Browning <bbrownin@redhat.com>.
-  * Some fixes to be compatible with the new Ruby 2.2 by Zachary Scott <e@zzak.io>
-    and SHIBATA Hiroshi <hsbt@ruby-lang.org>.
-
-## 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 <github_rocks@marc-andre.ca>. Thanks!
-  * Applied patches by Yui NARUSE <naruse@airemix.jp> 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 <jvshahid@gmail.com>, Thx!
-  * Add license information to rubygems spec data, reported by Jordi Massaguer Pla <jmassaguerpla@suse.de>.

-    everything to ascii-8bit; harmless for 1.8 mode too) (Thomas E. Enebo
-    <tom.enebo@gmail.com>), 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 <v.ondruch@tiscali.cz> reported a bug that shows up when using
-    optimisation under GCC 4.7. Thx to him, Bohuslav Kabrda
-    <bkabrda@redhat.com> and Yui NARUSE <naruse@airemix.jp> for debugging and
-    developing a patch fix.
-
-## 2011-12-24 (1.6.4)

-  * 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

-    jfirebaugh@github).
-  * Apply patch by Eric Wong <nocode@yhbt.net> 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.

-  * 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 <cory.monty@gmail.com>.
-  * 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

-
-## 2011-01-24 (1.5.1)
-  * Made rake-compiler build a fat binary gem. This should fix issue

-
-## 2011-01-22 (1.5.0)
-  * Included Java source codes for the Jruby extension made by Daniel Luz
-    <dev@mernen.com>.
-  * 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 <naruse@airemix.com> to make building with
-    Microsoft Visual C possible again.
-  * Applied patch from devrandom <c1.github@niftybox.net> in order to allow building of
-    json_pure if extensiontask is not present.
-  * Thanks to Dustin Schneider <dustin@stocktwits.com>, 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 <dan@kallistec.com>, 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 <sakuro@2238club.org> 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 <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 `\` 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. Thanks for the report go
-    to Florian Munz <surf@theflow.de>.
-
-## 2005-09-23 (0.4.0)
-  * Initial Rubyforge Version
