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.
Version 2.0.1
=============
Released 2011-03-31
* Bug fixes:
- Replace a few `malloc()` and `free()` calls with their
counterparts that support custom memory management.
- Fix object key hashing in json_unpack() strict checking mode.
- Fix the parentheses in ``JANSSON_VERSION_HEX`` macro.
- Fix `json_object_size()` return value.
- Fix a few compilation issues.
* Portability:
- Enhance portability of `va_copy()`.
- Test framework portability enhancements.
* Documentation:
- Distribute ``doc/upgrading.rst`` with the source tarball.
- Build documentation in strict mode in ``make distcheck``.
Version 2.0
===========
Released 2011-02-28
This release is backwards incompatible with the 1.x release series.
See the chapter "Upgrading from older versions" in documentation for
details.
* Backwards incompatible changes:
- Unify unsigned integer usage in the API: All occurences of
unsigned int and unsigned long have been replaced with size_t.
- Change JSON integer's underlying type to the widest signed integer
type available, i.e. long long if it's supported, otherwise long.
Add a typedef json_int_t that defines the type.
- Change the maximum indentation depth to 31 spaces in encoder. This
frees up bits from the flags parameter of encoding functions
`json_dumpf()`, `json_dumps()` and `json_dump_file()`.
- For future needs, add a flags parameter to all decoding functions
`json_loadf()`, `json_loads()` and `json_load_file()`.
* New features
- `json_pack()`, `json_pack_ex()`, `json_vpack_ex()`: Create JSON
values based on a format string.
- `json_unpack()`, `json_unpack_ex()`, `json_vunpack_ex()`: Simple
value extraction and validation functionality based on a format
string.
- Add column, position and source fields to the ``json_error_t``
struct.
- Enhance error reporting in the decoder.
- ``JANSSON_VERSION`` et al.: Preprocessor constants that define the
library version.
- `json_set_alloc_funcs()`: Set custom memory allocation functions.
* Fix many portability issues, especially on Windows.
* Configuration
- Add file ``jansson_config.h`` that contains site specific
configuration. It's created automatically by the configure script,
or can be created by hand if the configure script cannot be used.
The file ``jansson_config.h.win32`` can be used without
modifications on Windows systems.
- Add a section to documentation describing how to build Jansson on
Windows.
- Documentation now requires Sphinx 1.0 or newer.
Version 1.3
===========
Released 2010-06-13
* New functions:
- `json_object_iter_set()`, `json_object_iter_set_new()`: Change
object contents while iterating over it.
- `json_object_iter_at()`: Return an iterator that points to a
specific object item.
* New encoding flags:
- ``JSON_PRESERVE_ORDER``: Preserve the insertion order of object
keys.
* Bug fixes:
- Fix an error that occured when an array or object was first
encoded as empty, then populated with some data, and then
re-encoded
- Fix the situation like above, but when the first encoding resulted
in an error
* Documentation:
- Clarify the documentation on reference stealing, providing an
example usage pattern
Version 1.2.1
=============
Released 2010-04-03
* Bug fixes:
- Fix reference counting on ``true``, ``false`` and ``null``
- Estimate real number underflows in decoder with 0.0 instead of
issuing an error
* Portability:
- Make ``int32_t`` available on all systems
- Support compilers that don't have the ``inline`` keyword
- Require Autoconf 2.60 (for ``int32_t``)
* Tests:
- Print test names correctly when ``VERBOSE=1``
- ``test/suites/api``: Fail when a test fails
- Enhance tests for iterators
- Enhance tests for decoding texts that contain null bytes
* Documentation:
- Don't remove ``changes.rst`` in ``make clean``
- Add a chapter on RFC conformance
Version 1.2
===========
Released 2010-01-21
* New functions:
- `json_equal()`: Test whether two JSON values are equal
- `json_copy()` and `json_deep_copy()`: Make shallow and deep copies
of JSON values
- Add a version of all functions taking a string argument that
doesn't check for valid UTF-8: `json_string_nocheck()`,
`json_string_set_nocheck()`, `json_object_set_nocheck()`,
`json_object_set_new_nocheck()`
* New encoding flags:
- ``JSON_SORT_KEYS``: Sort objects by key
- ``JSON_ENSURE_ASCII``: Escape all non-ASCII Unicode characters
- ``JSON_COMPACT``: Use a compact representation with all unneeded
whitespace stripped
* Bug fixes:
- Revise and unify whitespace usage in encoder: Add spaces between
array and object items, never append newline to output.
- Remove const qualifier from the ``json_t`` parameter in
`json_string_set()`, `json_integer_set()` and `json_real_set`.
- Use ``int32_t`` internally for representing Unicode code points
(int is not enough on all platforms)
* Other changes:
- Convert ``CHANGES`` (this file) to reStructured text and add it to
HTML documentation
- The test system has been refactored. Python is no longer required
to run the tests.
- Documentation can now be built by invoking ``make html``
- Support for pkg-config
