8 - `json_unpack()` and friends: Add support for optional object keys
9 with the ``{s?o}`` syntax.
11 - Add `json_object_update_existing()` and
12 `json_object_update_missing()`, for updating only existing keys or
13 only adding missing keys to an object. (#37)
15 - Add `json_object_foreach()` for more convenient iteration over
18 - When decoding JSON, write the number of bytes that were read from
19 input to ``error.position`` also on success. This is handy with
20 ``JSON_DISABLE_EOF_CHECK``.
22 - Add support for decoding any JSON value, not just arrays or
23 objects. The support is enabled with the new ``JSON_DECODE_ANY``
24 flag. Patch by Andrea Marchesini. (#4)
28 - Avoid problems with object's serial number growing too big. (#40,
31 - Decoding functions now return NULL if the first argument is NULL.
32 Patch by Andrea Marchesini.
34 - Include ``jansson_config.h.win32`` in the distribution tarball.
36 - Remove ``+`` and leading zeros from exponents in the encoder.
39 - Make Jansson build and work on MinGW. (#39, #38)
43 - Note that the same JSON values must not be encoded in parallel by
44 separate threads. (#42)
46 - Document MinGW support.
56 - Fix real number encoding and decoding under non-C locales. (#32)
58 - Fix identifier decoding under non-UTF-8 locales. (#35)
60 - `json_load_file()`: Open the input file in binary mode for maximum
65 - Clarify the lifecycle of the result of the ``s`` fromat of
66 `json_unpack()`. (#31)
68 - Add some portability info. (#36)
70 - Little clarifications here and there.
74 - Some style fixes, issues detected by static analyzers.
84 - `json_dump_callback()`: Pass the encoder output to a callback
89 - `json_string_set()`: Check that target is a string and value is
94 - Documentation typo fixes and clarifications.
104 - `json_loadb()`: Decode a string with a given size, useful if the
105 string is not null terminated.
107 - Add ``JSON_ENCODE_ANY`` encoding flag to allow encoding any JSON
108 value. By default, only arrays and objects can be encoded. (#19)
110 - Add ``JSON_REJECT_DUPLICATES`` decoding flag to issue a decoding
111 error if any JSON object in the input contins duplicate keys. (#3)
113 - Add ``JSON_DISABLE_EOF_CHECK`` decoding flag to stop decoding after a
114 valid JSON input. This allows other data after the JSON data.
118 - Fix an additional memory leak when memory allocation fails in
119 `json_object_set()` and friends.
121 - Clear errno before calling `strtod()` for better portability. (#27)
125 - Avoid set-but-not-used warning/error in a test. (#20)
129 - Minor clarifications to documentation.
139 - Replace a few `malloc()` and `free()` calls with their
140 counterparts that support custom memory management.
142 - Fix object key hashing in json_unpack() strict checking mode.
144 - Fix the parentheses in ``JANSSON_VERSION_HEX`` macro.
146 - Fix `json_object_size()` return value.

158 - Distribute ``doc/upgrading.rst`` with the source tarball.
160 - Build documentation in strict mode in ``make distcheck``.
168 This release is backwards incompatible with the 1.x release series.
169 See the chapter "Upgrading from older versions" in documentation for
172 * Backwards incompatible changes:
174 - Unify unsigned integer usage in the API: All occurences of
175 unsigned int and unsigned long have been replaced with size_t.
177 - Change JSON integer's underlying type to the widest signed integer
178 type available, i.e. long long if it's supported, otherwise long.
179 Add a typedef json_int_t that defines the type.
181 - Change the maximum indentation depth to 31 spaces in encoder. This
182 frees up bits from the flags parameter of encoding functions
183 `json_dumpf()`, `json_dumps()` and `json_dump_file()`.
185 - For future needs, add a flags parameter to all decoding functions
186 `json_loadf()`, `json_loads()` and `json_load_file()`.
190 - `json_pack()`, `json_pack_ex()`, `json_vpack_ex()`: Create JSON
191 values based on a format string.
193 - `json_unpack()`, `json_unpack_ex()`, `json_vunpack_ex()`: Simple
194 value extraction and validation functionality based on a format
197 - Add column, position and source fields to the ``json_error_t``
200 - Enhance error reporting in the decoder.
202 - ``JANSSON_VERSION`` et al.: Preprocessor constants that define the
205 - `json_set_alloc_funcs()`: Set custom memory allocation functions.
207 * Fix many portability issues, especially on Windows.
211 - Add file ``jansson_config.h`` that contains site specific
212 configuration. It's created automatically by the configure script,
213 or can be created by hand if the configure script cannot be used.
214 The file ``jansson_config.h.win32`` can be used without
215 modifications on Windows systems.
217 - Add a section to documentation describing how to build Jansson on
220 - Documentation now requires Sphinx 1.0 or newer.
230 - `json_object_iter_set()`, `json_object_iter_set_new()`: Change
231 object contents while iterating over it.
233 - `json_object_iter_at()`: Return an iterator that points to a
234 specific object item.
236 * New encoding flags:
238 - ``JSON_PRESERVE_ORDER``: Preserve the insertion order of object
243 - Fix an error that occured when an array or object was first
244 encoded as empty, then populated with some data, and then
247 - Fix the situation like above, but when the first encoding resulted
252 - Clarify the documentation on reference stealing, providing an
253 example usage pattern
263 - Fix reference counting on ``true``, ``false`` and ``null``
264 - Estimate real number underflows in decoder with 0.0 instead of
269 - Make ``int32_t`` available on all systems
270 - Support compilers that don't have the ``inline`` keyword
271 - Require Autoconf 2.60 (for ``int32_t``)
275 - Print test names correctly when ``VERBOSE=1``
276 - ``test/suites/api``: Fail when a test fails
277 - Enhance tests for iterators
278 - Enhance tests for decoding texts that contain null bytes
282 - Don't remove ``changes.rst`` in ``make clean``
283 - Add a chapter on RFC conformance
293 - `json_equal()`: Test whether two JSON values are equal
294 - `json_copy()` and `json_deep_copy()`: Make shallow and deep copies
296 - Add a version of all functions taking a string argument that
297 doesn't check for valid UTF-8: `json_string_nocheck()`,
298 `json_string_set_nocheck()`, `json_object_set_nocheck()`,
299 `json_object_set_new_nocheck()`
301 * New encoding flags:
303 - ``JSON_SORT_KEYS``: Sort objects by key
304 - ``JSON_ENSURE_ASCII``: Escape all non-ASCII Unicode characters
305 - ``JSON_COMPACT``: Use a compact representation with all unneeded
310 - Revise and unify whitespace usage in encoder: Add spaces between
311 array and object items, never append newline to output.
312 - Remove const qualifier from the ``json_t`` parameter in
313 `json_string_set()`, `json_integer_set()` and `json_real_set`.
314 - Use ``int32_t`` internally for representing Unicode code points
315 (int is not enough on all platforms)
319 - Convert ``CHANGES`` (this file) to reStructured text and add it to
321 - The test system has been refactored. Python is no longer required
323 - Documentation can now be built by invoking ``make html``
324 - Support for pkg-config
332 * Encode reals correctly, so that first encoding and then decoding a
333 real always produces the same value
334 * Don't export private symbols in ``libjansson.so``
342 * Fix a bug where an error message was not produced if the input file
343 could not be opened in `json_load_file()`
344 * Fix an assertion failure in decoder caused by a minus sign without a
346 * Remove an unneeded include of ``stdint.h`` in ``jansson.h``
354 * All documentation files were not distributed with v1.1; build
355 documentation in make distcheck to prevent this in the future

364 * API additions and improvements:
366 - Extend array and object APIs
367 - Add functions to modify integer, real and string values
