+Version 2.4
+===========
+
+Released 2012-09-23
+
+* New features:
+
+  - Add `json_boolean()` macro that returns the JSON true or false
+    value based on its argument (#86).
+
+  - Add `json_load_callback()` that calls a callback function
+    repeatedly to read the JSON input (#57).
+
+  - Add JSON_ESCAPE_SLASH encoding flag to escape all occurences of
+    ``/`` with ``\/``.
+
+* Bug fixes:
+
+  - Check for and reject NaN and Inf values for reals. Encoding these
+    values resulted in invalid JSON.
+
+  - Fix `json_real_set()` to return -1 on error.
+
+* Build:
+
+  - Jansson now builds on Windows with Visual Studio 2010, and
+    includes solution and project files in ``win32/vs2010/``
+    directory.
+
+  - Fix build warnings (#77, #78).
+
+  - Add ``-no-undefined`` to LDFLAGS (#90).
+
+* Tests:
+
+  - Fix the symbol exports test on Linux/PPC64 (#88).
+
+* Documentation:
+
+  - Fix typos (#73, #84).
+
+
+Version 2.3.1
+=============
+
+Released 2012-04-20
+
+* Build issues:
+
+  - Only use ``long long`` if ``strtoll()`` is also available.
+
+* Documentation:
+
+  - Fix the names of library version constants in documentation. (#52)
+
+  - Change the tutorial to use GitHub API v3. (#65)
+
+* Tests:
+
+  - Make some tests locale independent. (#51)
+
+  - Distribute the library exports test in the tarball.
+
+  - Make test run on shells that don't support the ``export FOO=bar``
+    syntax.
+
+
+Version 2.3
+===========
+
+Released 2012-01-27
+
+* New features:
+
+  - `json_unpack()` and friends: Add support for optional object keys
+    with the ``{s?o}`` syntax.
+
+  - Add `json_object_update_existing()` and
+    `json_object_update_missing()`, for updating only existing keys or
+    only adding missing keys to an object. (#37)
+
+  - Add `json_object_foreach()` for more convenient iteration over
+    objects. (#45, #46)
+
+  - When decoding JSON, write the number of bytes that were read from
+    input to ``error.position`` also on success. This is handy with
+    ``JSON_DISABLE_EOF_CHECK``.
+
+  - Add support for decoding any JSON value, not just arrays or
+    objects. The support is enabled with the new ``JSON_DECODE_ANY``
+    flag. Patch by Andrea Marchesini. (#4)
+
+* Bug fixes
+
+  - Avoid problems with object's serial number growing too big. (#40,
+    #41)
+
+  - Decoding functions now return NULL if the first argument is NULL.
+    Patch by Andrea Marchesini.
+
+  - Include ``jansson_config.h.win32`` in the distribution tarball.
+
+  - Remove ``+`` and leading zeros from exponents in the encoder.
+    (#39)
+
+  - Make Jansson build and work on MinGW. (#39, #38)
+
+* Documentation
+
+  - Note that the same JSON values must not be encoded in parallel by
+    separate threads. (#42)
+
+  - Document MinGW support.
+
+
+Version 2.2.1
+=============
+
+Released 2011-10-06
+
+* Bug fixes:
+
+  - Fix real number encoding and decoding under non-C locales. (#32)
+
+  - Fix identifier decoding under non-UTF-8 locales. (#35)
+
+  - `json_load_file()`: Open the input file in binary mode for maximum
+    compatiblity.
+
+* Documentation:
+
+  - Clarify the lifecycle of the result of the ``s`` fromat of
+    `json_unpack()`. (#31)
+
+  - Add some portability info. (#36)
+
+  - Little clarifications here and there.
+
+* Other:
+
+  - Some style fixes, issues detected by static analyzers.
+
+
+Version 2.2
+===========
+
+Released 2011-09-03
+
+* New features:
+
+  - `json_dump_callback()`: Pass the encoder output to a callback
+    function in chunks.
+
+* Bug fixes:
+
+  - `json_string_set()`: Check that target is a string and value is
+    not NULL.
+
+* Other:
+
+  - Documentation typo fixes and clarifications.
+
+
+Version 2.1
+===========
+
+Released 2011-06-10
+
+* New features:
+
+  - `json_loadb()`: Decode a string with a given size, useful if the
+    string is not null terminated.
+
+  - Add ``JSON_ENCODE_ANY`` encoding flag to allow encoding any JSON
+    value. By default, only arrays and objects can be encoded. (#19)
+
+  - Add ``JSON_REJECT_DUPLICATES`` decoding flag to issue a decoding
+    error if any JSON object in the input contins duplicate keys. (#3)
+
+  - Add ``JSON_DISABLE_EOF_CHECK`` decoding flag to stop decoding after a
+    valid JSON input. This allows other data after the JSON data.
+
+* Bug fixes:
+
+  - Fix an additional memory leak when memory allocation fails in
+    `json_object_set()` and friends.
+
+  - Clear errno before calling `strtod()` for better portability. (#27)
+
+* Building:
+
+  - Avoid set-but-not-used warning/error in a test. (#20)
+
+* Other:
+
+  - Minor clarifications to documentation.

 See :ref:`rfc-conformance` for a discussion on Jansson's conformance

+``JSON_DISABLE_EOF_CHECK``
+   By default, the decoder expects that its whole input constitutes a

+   stops after decoding a valid JSON array or object, and thus allows

+
+   Normally, reading will stop when the last ``]`` or ``}`` in the
+   JSON input is encountered. If both ``JSON_DISABLE_EOF_CHECK`` and
+   ``JSON_DECODE_ANY`` flags are used, the decoder may read one extra
+   UTF-8 code unit (up to 4 bytes of input). For example, decoding
+   ``4true`` correctly decodes the integer 4, but also reads the

+
+Thread safety
+-------------
+
+Jansson is thread safe and has no mutable global state. The only
+exception are the memory allocation functions, that should be set at
+most once, and only on program startup. See
+:ref:`apiref-custom-memory-allocation`.
+
+There's no locking performed inside Jansson's code, so a multithreaded
+program must perform its own locking if JSON values are shared by
+multiple threads. Jansson's reference counting semantics may make this
+a bit harder than it seems, as it's possible to have a reference to a
+value that's also stored inside a list or object. Modifying the
+container (adding or removing values) may trigger concurrent access to
+such values, as containers manage the reference count of their
+contained values. Bugs involving concurrent incrementing or
+decrementing of deference counts may be hard to track.
+
+The encoding functions (:func:`json_dumps()` and friends) track
+reference loops by modifying the internal state of objects and arrays.
+For this reason, encoding functions must not be run on the same JSON
+values in two separate threads at the same time. As already noted
+above, be especially careful if two arrays or objects share their
+contained values with another array or object.
+
+If you want to make sure that two JSON value hierarchies do not
+contain shared values, use :func:`json_deep_copy()` to make copies.
+
+Locale
+------
+
+Jansson works fine under any locale.
+
+However, if the host program is multithreaded and uses ``setlocale()``
+to switch the locale in one thread while Jansson is currently encoding
+or decoding JSON data in another thread, the result may be wrong or
+the program may even crash.
+
+Jansson uses locale specific functions for certain string conversions
+in the encoder and decoder, and then converts the locale specific
+values to/from the JSON representation. This fails if the locale
+changes between the string conversion and the locale-to-JSON
+conversion. This can only happen in multithreaded programs that use
+``setlocale()``, because ``setlocale()`` switches the locale for all
+running threads, not only the thread that calls ``setlocale()``.
+
+If your program uses ``setlocale()`` as described above, consider
+using the thread-safe ``uselocale()`` instead.

 Conclusion
 ==========
 
 In this tutorial, we implemented a program that fetches the latest
-commits of a GitHub repository using the GitHub commits API. Jansson
-was used to decode the JSON response and to extract the commit data.
+commits of a GitHub repository using the GitHub Repo Commits API.
+Jansson was used to decode the JSON response and to extract the commit
+data.
 
 This tutorial only covered a small part of Jansson. For example, we
 did not create or manipulate JSON values at all. Proceed to
