compatibility.
- Disable Visual Studio warning C4756 when triggered deliberately in
tests
- Other minor fixes
* Other changes:
- List all unrecognized object keys when strict unpacking fails
- Alter the order of the members of the hashtable_pair struct for
easier debugging.
- Minor performance improvement to json_dump() and friends
- Minor style fixes
The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.
There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.

Version 2.7
===========
Released 2014-10-02
* New features:
- `json_pack()` and friends: Add format specifiers ``s%`` and ``+%``
for a size_t string length (#141).
- `json_unpack()` and friends: Add format specifier ``s%`` for
unpacking the string length along with the string itself (#141).
- Add length-aware string constructors `json_stringn()` and
`json_stringn_nocheck()`, length-aware string mutators
`json_string_setn()` and `json_string_setn_nocheck()`, and a
function for getting string's length `json_string_length()` (#141,
#143).
- Support ``\u0000`` escapes in the decoder. The support can be
enabled by using the ``JSON_ALLOW_NUL`` decoding flag (#141).

(#146).
- Add JSON_REAL_PRECISION encoding flag/macro for controlling real

hashtable.
- Check for *NULL* key in `json_object_get()` and
`json_object_del()` (#151).

Version 2.6
===========
Released 2014-02-11
* Security:
- CVE-2013-6401: The hash function used by the hashtable
implementation has been changed, and is automatically seeded with
random data when the first JSON object is created. This prevents
an attacker from causing large JSON objects with specially crafted
keys perform poorly.

- `json_object_seed()`: Set the seed value of the hash function.
* Bug fixes:
- Include CMake specific files in the release tarball.
* Documentation:
- Fix tutorial source to send a User-Agent header, which is now
required by the GitHub API.
- Set all memory to zero in secure_free() example.

* New features:
- `json_pack()` and friends: Add format specifiers ``s#``, ``+`` and
``+#``.
- Add ``JSON_DECODE_INT_AS_REAL`` decoding flag to treat all numbers
as real in the decoder (#123).
- Add `json_array_foreach()`, paralleling `json_object_foreach()`
(#118).
* Bug fixes:
- `json_dumps()` and friends: Don't crash if json is *NULL* and
``JSON_ENCODE_ANY`` is set.
- Fix a theoretical integer overflow in `jsonp_strdup()`.
