NEXT.VERSION
...nothing yet...
0.12
* Address security issues:
* CVE-2013-6371: hash collision denial of service
* CVE-2013-6370: buffer overflow if size_t is larger than int
* Avoid potential overflow in json_object_get_double
* Eliminate the mc_abort() function and MC_ABORT macro.
* Make the json_tokener_errors array local. It has been deprecated for
a while, and json_tokener_error_desc() should be used instead.
* change the floating point output format to %.17g so values with
more than 6 digits show up in the output.
* Remove the old libjson.so name compatibility support. The library is
only created as libjson-c.so now and headers are only installed
into the ${prefix}/json-c directory.
* When supported by the linker, add the -Bsymbolic-functions flag.
* Various changes to fix the build on MSVC.
* Make strict mode more strict:
* number must not start with 0
* no single-quote strings
* no comments
* trailing char not allowed
* only allow lowercase literals
* Added a json_object_new_double_s() convenience function to allow
an exact string representation of a double to be specified when
creating the object and use it in json_tokener_parse_ex() so
a re-serialized object more exactly matches the input.
* Add support NaN and Infinity
0.11
* IMPORTANT: the name of the library has changed to libjson-c.so and
the header files are now in include/json-c.
The pkgconfig name has also changed from json to json-c.
You should change your build to use appropriate -I and -l options.
A compatibility shim is in place so builds using the old name will
continue to work, but that will be removed in the next release.
* Maximum recursion depth is now a runtime option.
json_tokener_new() is provided for compatibility.
json_tokener_new_ex(depth)
* Include json_object_iterator.h in the installed headers.
* Add support for building on Android.
* Rewrite json_object_object_add to replace just the value if the key already exists so keys remain valid.
* Make it safe to delete keys while iterating with the json_object_object_foreach macro.
* Add a json_set_serializer() function to allow the string output of a json_object to be customized.
* Make float parsing locale independent.
* Add a json_tokener_set_flags() function and a JSON_TOKENER_STRICT flag.
* Enable -Werror when building.
* speed improvements to parsing 64-bit integers on systems with working sscanf
* Add a json_object_object_length function.
* Fix a bug (buffer overrun) when expanding arrays to more than 64 entries.
0.10
* Add a json_object_to_json_string_ext() function to allow output to be
formatted in a more human readable form.
* Add json_object_object_get_ex(), a NULL-safe get object method, to be able
to distinguish between a key not present and the value being NULL.
* Add an alternative iterator implementation, see json_object_iterator.h
* Make json_object_iter public to enable external use of the
json_object_object_foreachC macro.
* Add a printbuf_memset() function to provide an effecient way to set and
append things like whitespace indentation.
* Adjust json_object_is_type and json_object_get_type so they return
json_type_null for NULL objects and handle NULL passed to
json_objct_object_get().
* Rename boolean type to json_bool.
* Fix various compile issues for Visual Studio and MinGW.
* Allow json_tokener_parse_ex() to be re-used to parse multiple object.
Also, fix some parsing issues with capitalized hexadecimal numbers and
number in E notation.
* Add json_tokener_get_error() and json_tokener_error_desc() to better
encapsulate the process of retrieving errors while parsing.
* Various improvements to the documentation of many functions.
* Add new json_object_array_sort() function.
* Fix a bug in json_object_get_int(), which would incorrectly return 0
when called on a string type object.
Eric Haszlakiewicz
* Add a json_type_to_name() function.
Eric Haszlakiewicz
* Add a json_tokener_parse_verbose() function.
Jehiah Czebotar
* Improve support for null bytes within JSON strings.
Jehiah Czebotar
* Fix file descriptor leak if memory allocation fails in json_util
Zachary Blair, zack_blair at hotmail dot com
* Add int64 support. Two new functions json_object_net_int64 and
json_object_get_int64. Binary compatibility preserved.

Rui Miguel Silva Seabra, rms at 1407 dot org
