CHANGES

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


Version 1.1.3
=============

Released 2009-12-18

=============

Released 2009-11-08

  digit after it
* Remove an unneeded include of ``stdint.h`` in ``jansson.h``


Version 1.1.1
