  • v0.12-20140410

    April 11, 2014
  • v0.11 Changes

    April 03, 2013
    • IMPORTANT: the name of the library has changed to 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.
  • v0.11-20130402

    April 03, 2013
  • v0.10 Changes

    May 31, 2012
    • 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 efficient 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. Eric Haszlakiewicz, EHASZLA at transunion com Rui Miguel Silva Seabra, rms at 1407 dot org
    • Fix subtle bug in linkhash where lookup could hang after all slots were filled then successively freed. Spotted by Jean-Marc Naud, j dash m at newtraxtech dot com
