4 * Address security issues:
5 * CVE-2013-6371: hash collision denial of service
6 * CVE-2013-6370: buffer overflow if size_t is larger than int
8 * Avoid potential overflow in json_object_get_double
10 * Eliminate the mc_abort() function and MC_ABORT macro.
12 * Make the json_tokener_errors array local. It has been deprecated for
13 a while, and json_tokener_error_desc() should be used instead.
15 * change the floating point output format to %.17g so values with
16 more than 6 digits show up in the output.
18 * Remove the old libjson.so name compatibility support. The library is
19 only created as libjson-c.so now and headers are only installed
20 into the ${prefix}/json-c directory.
22 * When supported by the linker, add the -Bsymbolic-functions flag.
24 * Various changes to fix the build on MSVC.
26 * Make strict mode more strict:
27 * number must not start with 0
28 * no single-quote strings
30 * trailing char not allowed
31 * only allow lowercase literals
33 * Added a json_object_new_double_s() convenience function to allow
34 an exact string representation of a double to be specified when
35 creating the object and use it in json_tokener_parse_ex() so
36 a re-serialized object more exactly matches the input.
38 * Add support NaN and Infinity
43 * IMPORTANT: the name of the library has changed to libjson-c.so and
44 the header files are now in include/json-c.
45 The pkgconfig name has also changed from json to json-c.
46 You should change your build to use appropriate -I and -l options.
47 A compatibility shim is in place so builds using the old name will
48 continue to work, but that will be removed in the next release.
49 * Maximum recursion depth is now a runtime option.
50 json_tokener_new() is provided for compatibility.
51 json_tokener_new_ex(depth)
52 * Include json_object_iterator.h in the installed headers.
53 * Add support for building on Android.
54 * Rewrite json_object_object_add to replace just the value if the key already exists so keys remain valid.
55 * Make it safe to delete keys while iterating with the json_object_object_foreach macro.
56 * Add a json_set_serializer() function to allow the string output of a json_object to be customized.
57 * Make float parsing locale independent.
58 * Add a json_tokener_set_flags() function and a JSON_TOKENER_STRICT flag.
59 * Enable -Werror when building.
60 * speed improvements to parsing 64-bit integers on systems with working sscanf
61 * Add a json_object_object_length function.
62 * Fix a bug (buffer overrun) when expanding arrays to more than 64 entries.
66 * Add a json_object_to_json_string_ext() function to allow output to be
67 formatted in a more human readable form.
68 * Add json_object_object_get_ex(), a NULL-safe get object method, to be able
69 to distinguish between a key not present and the value being NULL.
70 * Add an alternative iterator implementation, see json_object_iterator.h
71 * Make json_object_iter public to enable external use of the
72 json_object_object_foreachC macro.
73 * Add a printbuf_memset() function to provide an effecient way to set and
74 append things like whitespace indentation.
75 * Adjust json_object_is_type and json_object_get_type so they return
76 json_type_null for NULL objects and handle NULL passed to
77 json_objct_object_get().
78 * Rename boolean type to json_bool.
79 * Fix various compile issues for Visual Studio and MinGW.
80 * Allow json_tokener_parse_ex() to be re-used to parse multiple object.
81 Also, fix some parsing issues with capitalized hexadecimal numbers and
83 * Add json_tokener_get_error() and json_tokener_error_desc() to better
84 encapsulate the process of retrieving errors while parsing.
85 * Various improvements to the documentation of many functions.
86 * Add new json_object_array_sort() function.
87 * Fix a bug in json_object_get_int(), which would incorrectly return 0
88 when called on a string type object.
90 * Add a json_type_to_name() function.
92 * Add a json_tokener_parse_verbose() function.
94 * Improve support for null bytes within JSON strings.
96 * Fix file descriptor leak if memory allocation fails in json_util
97 Zachary Blair, zack_blair at hotmail dot com
98 * Add int64 support. Two new functions json_object_net_int64 and
99 json_object_get_int64. Binary compatibility preserved.
