1 Version 2.1 (in development)
2 ============================
6 - `json_loadb()`: Decode a string with a given size, useful if the
7 string is not null terminated.
9 - Add ``JSON_ENCODE_ANY`` encoding flag to allow encoding any JSON
10 value. By default, only arrays and objects can be encoded. (#19)
12 - Add ``JSON_REJECT_DUPLICATES`` decoding flag to issue a decoding
13 error if any JSON object in the input contins duplicate keys. (#3)
15 - Add ``JSON_DISABLE_EOF_CHECK`` decoding flag to stop decoding after a
16 valid JSON input. This allows other data after the JSON data.
20 - Fix an additional memory leak when memory allocation fails in
21 `json_object_set()` and friends.
23 - Clear errno before calling `strtod()` for better portability. (#27)
27 - Avoid set-but-not-used warning/error in a test. (#20)
31 - Minor clarifications to documentation.
41 - Replace a few `malloc()` and `free()` calls with their
42 counterparts that support custom memory management.
44 - Fix object key hashing in json_unpack() strict checking mode.
46 - Fix the parentheses in ``JANSSON_VERSION_HEX`` macro.
48 - Fix `json_object_size()` return value.
50 - Fix a few compilation issues.
54 - Enhance portability of `va_copy()`.
56 - Test framework portability enhancements.
60 - Distribute ``doc/upgrading.rst`` with the source tarball.
62 - Build documentation in strict mode in ``make distcheck``.
70 This release is backwards incompatible with the 1.x release series.
71 See the chapter "Upgrading from older versions" in documentation for
74 * Backwards incompatible changes:
76 - Unify unsigned integer usage in the API: All occurences of
77 unsigned int and unsigned long have been replaced with size_t.
79 - Change JSON integer's underlying type to the widest signed integer
80 type available, i.e. long long if it's supported, otherwise long.
81 Add a typedef json_int_t that defines the type.
83 - Change the maximum indentation depth to 31 spaces in encoder. This
84 frees up bits from the flags parameter of encoding functions
85 `json_dumpf()`, `json_dumps()` and `json_dump_file()`.
87 - For future needs, add a flags parameter to all decoding functions
88 `json_loadf()`, `json_loads()` and `json_load_file()`.
92 - `json_pack()`, `json_pack_ex()`, `json_vpack_ex()`: Create JSON
93 values based on a format string.
95 - `json_unpack()`, `json_unpack_ex()`, `json_vunpack_ex()`: Simple
96 value extraction and validation functionality based on a format
99 - Add column, position and source fields to the ``json_error_t``
102 - Enhance error reporting in the decoder.
104 - ``JANSSON_VERSION`` et al.: Preprocessor constants that define the
107 - `json_set_alloc_funcs()`: Set custom memory allocation functions.
109 * Fix many portability issues, especially on Windows.
113 - Add file ``jansson_config.h`` that contains site specific
114 configuration. It's created automatically by the configure script,
115 or can be created by hand if the configure script cannot be used.
116 The file ``jansson_config.h.win32`` can be used without
117 modifications on Windows systems.
119 - Add a section to documentation describing how to build Jansson on
122 - Documentation now requires Sphinx 1.0 or newer.
132 - `json_object_iter_set()`, `json_object_iter_set_new()`: Change
133 object contents while iterating over it.
135 - `json_object_iter_at()`: Return an iterator that points to a
136 specific object item.
138 * New encoding flags:
140 - ``JSON_PRESERVE_ORDER``: Preserve the insertion order of object
145 - Fix an error that occured when an array or object was first
146 encoded as empty, then populated with some data, and then
149 - Fix the situation like above, but when the first encoding resulted
154 - Clarify the documentation on reference stealing, providing an
155 example usage pattern
165 - Fix reference counting on ``true``, ``false`` and ``null``
166 - Estimate real number underflows in decoder with 0.0 instead of
171 - Make ``int32_t`` available on all systems
172 - Support compilers that don't have the ``inline`` keyword
173 - Require Autoconf 2.60 (for ``int32_t``)
177 - Print test names correctly when ``VERBOSE=1``
178 - ``test/suites/api``: Fail when a test fails
179 - Enhance tests for iterators
180 - Enhance tests for decoding texts that contain null bytes
184 - Don't remove ``changes.rst`` in ``make clean``
185 - Add a chapter on RFC conformance
195 - `json_equal()`: Test whether two JSON values are equal
196 - `json_copy()` and `json_deep_copy()`: Make shallow and deep copies
198 - Add a version of all functions taking a string argument that
199 doesn't check for valid UTF-8: `json_string_nocheck()`,
200 `json_string_set_nocheck()`, `json_object_set_nocheck()`,
201 `json_object_set_new_nocheck()`
203 * New encoding flags:
205 - ``JSON_SORT_KEYS``: Sort objects by key
206 - ``JSON_ENSURE_ASCII``: Escape all non-ASCII Unicode characters
207 - ``JSON_COMPACT``: Use a compact representation with all unneeded
212 - Revise and unify whitespace usage in encoder: Add spaces between
213 array and object items, never append newline to output.
214 - Remove const qualifier from the ``json_t`` parameter in
215 `json_string_set()`, `json_integer_set()` and `json_real_set`.
216 - Use ``int32_t`` internally for representing Unicode code points
217 (int is not enough on all platforms)
221 - Convert ``CHANGES`` (this file) to reStructured text and add it to
223 - The test system has been refactored. Python is no longer required
225 - Documentation can now be built by invoking ``make html``
226 - Support for pkg-config
234 * Encode reals correctly, so that first encoding and then decoding a
235 real always produces the same value
236 * Don't export private symbols in ``libjansson.so``
244 * Fix a bug where an error message was not produced if the input file
245 could not be opened in `json_load_file()`
246 * Fix an assertion failure in decoder caused by a minus sign without a
248 * Remove an unneeded include of ``stdint.h`` in ``jansson.h``
256 * All documentation files were not distributed with v1.1; build
257 documentation in make distcheck to prevent this in the future
258 * Fix v1.1 release date in ``CHANGES``
266 * API additions and improvements:
268 - Extend array and object APIs
269 - Add functions to modify integer, real and string values
270 - Improve argument validation
271 - Use unsigned int instead of ``uint32_t`` for encoding flags
273 * Enhance documentation
275 - Add getting started guide and tutorial
277 - General clarifications and cleanup
279 * Check for integer and real overflows and underflows in decoder
280 * Make singleton values thread-safe (``true``, ``false`` and ``null``)
281 * Enhance circular reference handling
282 * Don't define ``-std=c99`` in ``AM_CFLAGS``
283 * Add C++ guards to ``jansson.h``
284 * Minor performance and portability improvements
285 * Expand test coverage
293 * Relax Autoconf version requirement to 2.59
294 * Make Jansson compile on platforms where plain ``char`` is unsigned
295 * Fix API tests for object
303 * Check for integer and real overflows and underflows in decoder
304 * Use the Python json module for tests, or simplejson if the json
306 * Distribute changelog (this file)
314 * Handle EOF correctly in decoder
322 * Fixed broken `json_is_boolean()`
