+# Changes
+
+## 2016-07-01 (2.0.1)
+  * Fix problem when requiring json\_pure and Parser constant was defiend 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 compatibiliy 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 improvemed 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
+    explicitely 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 explicitely 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>.
+  * Improve documentation, thx to Zachary Scott <zachary@zacharyscott.net>.
+
+## 2012-11-29 (1.7.6)

+   jvshahid@github.
+  * Increase hash likeness of state objects.

+  * 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
+    <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)
+  * Patches that improve speed on JRuby contributed by Charles Oliver Nutter
+    <headius@headius.com>.
+  * 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 <evan@phx.io> 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)

+  * Fix memory leak when used from multiple JRuby. (Patch by
+    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.
+
+## 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 <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
+    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
+    <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 comapatible 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 exeception 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
