## Deprecated and removed features:
* bits.h has been removed
* lh_abort() has been removed
* lh_table_lookup() has been removed, use lh_table_lookup_ex() instead.
* Remove TRUE and FALSE defines, use 1 and 0 instead.
* autoconf support, including autogen.sh, has been removed.  See details about \ 
cmake, below.
* With the addition of json_tokener_get_parse_end(), access to internal fields \ 
of json_tokener, as well as use of many other symbols and types in \ 
json_tokener.h, is deprecated now.
* The use of Android.configure.mk to build for Android no longer works, and it \ 
is unknown how (or if) the new cmake-based build machinery can be used.
    * Reports of success, or pull requests to correct issues are welcome.

## Notable improvements and new features

### Builds and documentation
* Build machinery has been switched to CMake.  See README.md for details about \ 
how to build.
    * TL;DR: `mkdir build ; cd build ; cmake -DCMAKE_INSTALL_PREFIX=/some/path \ 
../json-c ; make all test install`
    * To ease the transition, there is a `cmake-configure` wrapper that emulates \ 
the old autoconf-based configure script.
    * This has enabled improvements to the build on Windows system; also all \ 
public functions have been fixed to be properly exported.  For best results, use \ 
Visual Studio 2015 or newer.
* The json-c style guide has been updated to specify the use of clang-format, \ 
and all code has been reformatted.
    * Since many lines of code have trivial changes now, when using git blame, \ 
be sure to specify -w
* Numerous improvements have been made to the documentation including function \ 
effects on refcounts, when passing a NULL is safe, and so on.

### json_tokener changes
* Added a json_tokener_get_parse_end() function to replace direct access of \ 
tok->char_offset.
    * The char_offset field, and the rest of the json_tokener structure remain \ 
exposed for now, but expect a future release to hide it like is done with \ 
json_object_private.h
* json_tokener_parse_ex() now accepts a new JSON_TOKENER_VALIDATE_UTF8 flag to \ 
validate that input is UTF8.
    * If validation fails, json_tokener_get_error(tok) will return \ 
json_tokener_error_parse_utf8_string (see enum json_tokener_error).

### Other changes and additions
* Add support for unsigned 64-bit integers, uint64_t, to gain one extra bit of \ 
magnitude for positive ints.
    * json_tokener will now parse values up to UINT64_MAX (18446744073709551615)
    * Existing methods returning int32_t or int64_t will cap out-of-range values \ 
at INT32_MAX or INT64_MAX, preserving existing behavior.
    * The implementation includes the possibility of easily extending this to \ 
larger sizes in the future.
* A total of 7 new functions were added:
    * json_object_get_uint64 ( struct json_object const* jso )
    * json_object_new_uint64 ( uint64_t i )
    * json_object_set_uint64 ( struct json_object* jso, uint64_t new_value )
    * json_parse_uint64 ( char const* buf, uint64_t* retval )
        * See description of uint64 support, above.
    * json_tokener_get_parse_end ( struct json_tokener* tok )
        * See details under "json_tokener changes", above.
    * json_object_from_fd_ex ( int fd, int in_depth )
        * Allows the max nesting depth to be specified.
    * json_object_new_null ( )
        * Simply returns NULL.  Its use is not recommended.
* The size of struct json_object has decreased from 96 bytes to 88 bytes.

### Testing
* Many updates were made to test cases, increasing code coverage.
* There is now a quick way (JSONC_TEST_TRACE=1) to turn on shell tracing in tests.
* To run tests, use `make test`; the old "check" target no longer exists.

## Significant bug fixes
For the full list of issues and pull requests since the previous release, please \ 
see issues_closed_for_0.14.md

* [Issue #389](https://github.com/json-c/json-c/issues/389): Add an assert to \ 
explicitly crash when _ref_count is corrupted, instead of a later "double \ 
free" error.
* [Issue #407](https://github.com/json-c/json-c/issues/407): fix incorrect casts \ 
in calls to ctype functions (isdigit and isspace) so we don't crash when asserts \ 
are enabled on certain platforms and characters > 128 are parsed.
* [Issue #418](https://github.com/json-c/json-c/issues/418): Fix docs for \ 
json_util_from_fd and json_util_from_file to say that they return NULL on \ 
failures.
* [Issue #422](https://github.com/json-c/json-c/issues/422): json_object.c:set \ 
errno in json_object_get_double() when called on a json_type_string object with \ 
bad content.
* [Issue #453](https://github.com/json-c/json-c/issues/453): Fixed misalignment \ 
in JSON serialization when JSON_C_TO_STRING_SPACED and JSON_C_TO_STRING_PRETTY \ 
are used together.
* [Issue #463](https://github.com/json-c/json-c/issues/463): fix newlocale() \ 
call to use LC_NUMERIC_MASK instead of LC_NUMERIC, and remove incorrect comment.
* [Issue #486](https://github.com/json-c/json-c/issues/486): append a missing \ 
".0" to negative double values to ensure they are serialized as \ 
floating point numbers.
* [Issue #488](https://github.com/json-c/json-c/issues/488): use JSON_EXPORT on \ 
functions so they are properly exported on Windows.
* [Issue #539](https://github.com/json-c/json-c/issues/539): use an \ 
internal-only serializer function in json_object_new_double_s() to avoid \ 
potential conflicts with user code that uses the \ 
json_object_userdata_to_json_string serializer.
