json-c/ChangeLog

0.12.1

  * Minimal changes to address compile issues.

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.
