+0.16 (up to commit 66dcdf5, 2022-04-13)
+========================================
+
+Deprecated and removed features:
+--------------------------------
+* JSON_C_OBJECT_KEY_IS_CONSTANT is deprecated in favor of
+  JSON_C_OBJECT_ADD_CONSTANT_KEY
+* Direct access to lh_table and lh_entry structure members is deprecated.  
+  Use access functions instead, lh_table_head(), lh_entry_next(), etc...
+* Drop REFCOUNT_DEBUG code.
+
+New features
+------------
+* The 0.16 release introduces no new features
+
+Build changes
+-------------
+* Add a DISABLE_EXTRA_LIBS option to skip using libbsd
+* Add a DISABLE_JSON_POINTER option to skip compiling in json_pointer support.
+
+Significant changes and bug fixes
+---------------------------------
+* Cap string length at INT_MAX to avoid various issues with very long strings.
+* json_object_deep_copy: fix deep copy of strings containing '\0'
+* Fix read past end of buffer in the "json_parse" command
+* Avoid out of memory accesses in the locally provided vasprintf() function
+  (for those platforms that use it)
+* Handle allocation failure in json_tokener_new_ex
+* Fix use-after-free in json_tokener_new_ex() in the event of printbuf_new() returning NULL
+* printbuf_memset(): set gaps to zero - areas within the print buffer which
+  have not been initialized by using printbuf_memset
+* printbuf: return -1 on invalid arguments (len < 0 or total buffer > INT_MAX)
+* sprintbuf(): propagate printbuf_memappend errors back to the caller
+
+Optimizations
+--------------
+* Speed up parsing by replacing ctype functions with simplified, faster 
+  non-locale-sensitive ones in json_tokener and json_object_to_json_string.
+* Neither vertical tab nor formfeed are considered whitespace per the JSON spec
+* json_object: speed up creation of objects, calloc() -> malloc() + set fields
+* Avoid needless extra strlen() call in json_c_shallow_copy_default() and
+  json_object_equal() when the object is known to be a json_type_string.
+
+Other changes
+-------------
+* Validate size arguments in arraylist functions.
+* Use getrandom() if available; with GRND_NONBLOCK to allow use of json-c
+  very early during boot, such as part of cryptsetup.
+* Use arc4random() if it's available.
+* random_seed: on error, continue to next method instead of exiting the process
+* Close file when unable to read from /dev/urandom in get_dev_random_seed()
+
+***
+
+0.15 (up to commit 870965e, 2020/07/26)
+========================================
+
+Deprecated and removed features:
+--------------------------------
+* Deprecate `array_list_new()` in favor of `array_list_new2()`
+* Remove the THIS_FUNCTION_IS_DEPRECATED define.
+* Remove config.h.win32
+
+New features
+------------
+* Add a `JSON_TOKENER_ALLOW_TRAILING_CHARS` flag to allow multiple objects
+  to be parsed even when `JSON_TOKENER_STRICT` is set.
+* Add `json_object_new_array_ext(int)` and `array_list_new_2(int)` to allow
+   arrays to be allocated with the exact size needed, when known.
+* Add `json_object_array_shrink()` (and `array_list_shrink()`) and use it in 
+   json_tokener to minimize the amount of memory used.
+* Add a json_parse binary, for use in testing changes (not installed, but 
+   available in the apps directory).
+
+Build changes
+-------------
+* #639/#621 - Add symbol versions to all exported symbols
+* #508/#634 - Always enable -fPIC to allow use of the json-c static library in
+   other libraries
+* Build both static and shared libraries at the same time.
+* #626 - Restore compatibility with cmake 2.8 
+* #471 - Always create directories with mode 0755, regardless of umask.
+* #606/#604 - Improve support for OSes like AIX and IBM i, as well as for
+   MINGW32 and old versions of MSVC
+* #451/#617 - Add a DISABLE_THREAD_LOCAL_STORAGE cmake option to disable 
+   the use of thread-local storage.
+
+Significant changes and bug fixes
+---------------------------------
+* Split the internal json_object structure into several sub-types, one for
+   each json_type (json_object_object, json_object_string, etc...).
+  This improves memory usage and speed, with the benchmark under
+   bench/ report 5.8% faster test time and 6%(max RSS)-12%(peak heap)
+   less memory usage.
+  Memory used just for json_object structures decreased 27%, so use cases
+   with fewer arrays and/or strings would benefit more.
+* Minimize memory usage in array handling in json_tokener by shrinking
+   arrays to the exact number of elements parsed.  On bench/ benchmark:
+   9% faster test time, 39%(max RSS)-50%(peak heap) less memory usage.
+   Add json_object_array_shrink() and array_list_shrink() functions.
+* #616 - Parsing of surrogate pairs in unicode escapes now properly handles
+   incremental parsing.
+* Fix incremental parsing of numbers, especially those with exponents, e.g.
+   so parsing "[0", "e+", "-]" now properly returns an error.
+  Strict mode now rejects missing exponents ("0e").
+* Successfully return number objects at the top level even when they are
+   followed by a "-", "." or "e".  This makes parsing things like "123-45"
+   behave consistently with things like "123xyz".
+
+Other changes
+-------------
+* #589 - Detect broken RDRAND during initialization; also, fix segfault
+    in the CPUID check.
+* #592 - Fix integer overflows to prevert out of bounds write on large input.
+* Protect against division by zero in linkhash, when created with zero size.
+* #602 - Fix json_parse_uint64() internal error checking, leaving the retval
+    untouched in more failure cases.
+* #614 - Prevent truncation when custom double formatters insert extra \0's
+

+0.14 (up to commit 9ed00a6, 2020/04/14)
+=========================================
+
+Deprecated and removed features:
+--------------------------------
+* bits.h has been removed
+* lh_abort() has been removed
+* lh_table_lookup() has been removed, use lh_table_lookup_ex() instead.
+* Remove TRUE and FALSE defines, use 1 and 0 instead.
+
+Build changes:
+--------------
+## Deprecated and removed features:
+* bits.h has been removed
+* lh_abort() has been removed
+* lh_table_lookup() has been removed, use lh_table_lookup_ex() instead.
+* Remove TRUE and FALSE defines, use 1 and 0 instead.
+* autoconf support, including autogen.sh, has been removed.  See details about cmake, below.
+* With the addition of json_tokener_get_parse_end(), access to internal fields of json_tokener, as well as use of many other symbols and types in json_tokener.h, is deprecated now.
+* The use of Android.configure.mk to build for Android no longer works, and it is unknown how (or if) the new cmake-based build machinery can be used.
+    * Reports of success, or pull requests to correct issues are welcome.
+
+## Notable improvements and new features
+
+### Builds and documentation
+* Build machinery has been switched to CMake.  See README.md for details about how to build.
+    * TL;DR: `mkdir build ; cd build ; cmake -DCMAKE_INSTALL_PREFIX=/some/path ../json-c ; make all test install`
+    * To ease the transition, there is a `cmake-configure` wrapper that emulates the old autoconf-based configure script.
+    * This has enabled improvements to the build on Windows system; also all public functions have been fixed to be properly exported.  For best results, use Visual Studio 2015 or newer.
+* The json-c style guide has been updated to specify the use of clang-format, and all code has been reformatted.
+    * Since many lines of code have trivial changes now, when using git blame, be sure to specify -w
+* Numerous improvements have been made to the documentation including function effects on refcounts, when passing a NULL is safe, and so on.
+
+### json_tokener changes
+* Added a json_tokener_get_parse_end() function to replace direct access of tok->char_offset.
+    * The char_offset field, and the rest of the json_tokener structure remain exposed for now, but expect a future release to hide it like is done with json_object_private.h
+* json_tokener_parse_ex() now accepts a new JSON_TOKENER_VALIDATE_UTF8 flag to validate that input is UTF8.
+    * If validation fails, json_tokener_get_error(tok) will return json_tokener_error_parse_utf8_string (see enum json_tokener_error).
+
+### Other changes and additions
+* Add support for unsigned 64-bit integers, uint64_t, to gain one extra bit of magnitude for positive ints.
+    * json_tokener will now parse values up to UINT64_MAX (18446744073709551615)
+    * Existing methods returning int32_t or int64_t will cap out-of-range values at INT32_MAX or INT64_MAX, preserving existing behavior.
+    * The implementation includes the possibility of easily extending this to larger sizes in the future.
+* A total of 7 new functions were added:
+    * json_object_get_uint64 ( struct json_object const* jso )
+    * json_object_new_uint64 ( uint64_t i )
+    * json_object_set_uint64 ( struct json_object* jso, uint64_t new_value )
+    * json_parse_uint64 ( char const* buf, uint64_t* retval )
+        * See description of uint64 support, above.
+    * json_tokener_get_parse_end ( struct json_tokener* tok )
+        * See details under "json_tokener changes", above.
+    * json_object_from_fd_ex ( int fd, int in_depth )
+        * Allows the max nesting depth to be specified.
+    * json_object_new_null ( )
+        * Simply returns NULL.  Its use is not recommended.
+* The size of struct json_object has decreased from 96 bytes to 88 bytes.
+
+### Testing
+* Many updates were made to test cases, increasing code coverage.
+* There is now a quick way (JSONC_TEST_TRACE=1) to turn on shell tracing in tests.
+* To run tests, use `make test`; the old "check" target no longer exists.
+
+## Significant bug fixes
+For the full list of issues and pull requests since the previous release, please see issues_closed_for_0.14.md
+
+* [Issue #389](https://github.com/json-c/json-c/issues/389): Add an assert to explicitly crash when _ref_count is corrupted, instead of a later "double free" error.
+* [Issue #407](https://github.com/json-c/json-c/issues/407): fix incorrect casts in calls to ctype functions (isdigit and isspace) so we don't crash when asserts are enabled on certain platforms and characters > 128 are parsed.
+* [Issue #418](https://github.com/json-c/json-c/issues/418): Fix docs for json_util_from_fd and json_util_from_file to say that they return NULL on failures.
+* [Issue #422](https://github.com/json-c/json-c/issues/422): json_object.c:set errno in json_object_get_double() when called on a json_type_string object with bad content.
+* [Issue #453](https://github.com/json-c/json-c/issues/453): Fixed misalignment in JSON serialization when JSON_C_TO_STRING_SPACED and JSON_C_TO_STRING_PRETTY are used together.
+* [Issue #463](https://github.com/json-c/json-c/issues/463): fix newlocale() call to use LC_NUMERIC_MASK instead of LC_NUMERIC, and remove incorrect comment.
+* [Issue #486](https://github.com/json-c/json-c/issues/486): append a missing ".0" to negative double values to ensure they are serialized as floating point numbers.
+* [Issue #488](https://github.com/json-c/json-c/issues/488): use JSON_EXPORT on functions so they are properly exported on Windows.
+* [Issue #539](https://github.com/json-c/json-c/issues/539): use an internal-only serializer function in json_object_new_double_s() to avoid potential conflicts with user code that uses the json_object_userdata_to_json_string serializer.
+
+***
+
+0.13.1 (up to commit 0f814e5, 2018/03/04)
+=========================================
+
+* Bump the major version of the .so library generated up to 4.0 to avoid
+  conflicts because some downstream packagers of json-c had already done
+  their own bump to ".so.3" for a much older 0.12 release.
+* Add const size_t json_c_object_sizeof()
+* Avoid invalid free (and thus a segfault) when ref_count gets < 0
+* PR#394: fix handling of custom double formats that include a ".0"
+* Avoid uninitialized variable warnings in json_object_object_foreach
+* Issue #396: fix build for certain uClibc based systems.
+* Add a top level fuzz directory for fuzzers run by OSS-Fuzz
+
+
+0.13 (up to commit 5dae561, 2017/11/29)
+=================================
+
+This release, being three and a half years after the 0.12 branch (f84d9c),
+   has quite a number of changes included.  The following is a sampling of
+   the most significant ones.
+
+Since the 0.12 release, 250 issues and pull requests have been closed.
+See issues_closed_for_0.13.md for a complete list.
+
+
+Deprecated and removed features:
+--------------------------------
+* All internal use of bits.h has been eliminated.  The file will be removed.
+	Do not use: hexdigit(), error_ptr(), error_descrition() and it_error()
+* lh_abort() is deprecated.  It will be removed.
+
+Behavior changes:
+-----------------
+* Tighten the number parsing algorithm to raise errors instead of truncating
+     the results.  For example 12.3.4 or 2015-01-15, which now return null.
+	 See commit 99d8fc
+
+* Use size_t for array length and size.  Platforms where sizeof(size_t) != sizeof(int) may not be backwards compatible
+	See commits 45c56b, 92e9a5 and others.
+
+* Check for failure when allocating memory, returning NULL and errno=ENOMEM.
+	 See commit 2149a04.
+
+* Change json_object_object_add() return type from void to int, and will return -1 on failures, instead of exiting. (Note: this is not an ABI change)
+
+New features:
+-------------
+* We're aiming to follow RFC 7159 now.
+
+* Add a couple of additional option to json_object_to_json_string_ext:
+	JSON_C_TO_STRING_PRETTY_TAB
+	JSON_C_TO_STRING_NOSLASHESCAPE
+
+* Add a json_object_object_add_ex() function to allow for performance
+	improvements when certain constraints are known to be true.
+
+* Make serialization format of doubles configurable, in two different ways:
+	Call json_object_set_serializer with json_object_double_to_json_string and a custom
+	 format on each double object, or
+	Call json_c_set_serialization_double_format() to set a global or thread-wide format.
+
+* Add utility function for comparing json_objects - json_object_equal()
+
+* Add a way to copy entire object trees: json_object_deep_copy()
+* Add json_object_set_<type> function to modify the value of existing json_object's
+ without the need to recreate them.  Also add a json_object_int_inc function to
+ adjust an int's value.
+* Add support for JSON pointer, RFC 6901.  See json_pointer.h
+* Add a json_util_get_last_err() function to retrieve the string describing the
+ cause of errors, instead of printing to stderr.
+* Add perllike hash function for strings, and json_global_set_string_hash() 8f8d03d
+* Add a json_c_visit() function to provide a way to iterate over a tree of json-c objects.
+
+Notable bug fixes and other improvements:
+-----------------------------------------
+* Make reference increment and decrement atomic to allow passing json objects between threads.
+* Fix json_object_object_foreach to avoid uninitialized variable warnings.
+* Improve performance by removing unneeded data items from hashtable code and reducing duplicate hash computation.
+* Improve performance by storing small strings inside json_object
+* Improve performance of json_object_to_json_string by removing variadic printf. commit 9ff0f49
+* Issue #371: fix parsing of "-Infinity", and avoid needlessly copying the input when doing so.
+* Fix stack buffer overflow in json_object_double_to_json_string_format() - commit 2c2deb87
+* Fix various potential null ptr deref and int32 overflows
+* Issue #332: fix a long-standing bug in array_list_put_idx() where it would attempt to free previously free'd entries due to not checking the current array length.
+* Issue #195: use uselocale() instead of setlocale() in json_tokener to behave better in threaded environments.
+* Issue #275: fix out of bounds read when handling unicode surrogate pairs.
+* Ensure doubles that happen to be a whole number are emitted with ".0" - commit ca7a19
+* PR#331: for Visual Studio, use a snprintf/vsnprintf wrapper that ensures the string is terminated.
+* Fix double to int cast overflow in json_object_get_int64.
+* Clamp double to int32 when narrowing in json_object_get_int.
+* Use strtoll() to parse ints - instead of sscanf
+* Miscellaneous smaller changes, including removing unused variables, fixing warning
+ about uninitialized variables adding const qualifiers, reformatting code, etc...
+
+Build changes:
+--------------
+* Add Appveyor and Travis build support
+* Switch to using CMake when building on Windows with Visual Studio.
+	A dynamic .dll is generated instead of a .lib
+	config.h is now generated, config.h.win32 should no longer be manually copied
+* Add support for MacOS through CMake too.
+* Enable silent build by default
+* Link against libm when needed
+* Add support for building with AddressSanitizer
+* Add support for building with Clang
+* Add a --enable-threading configure option, and only use the (slower) __sync_add_and_fetch()/__sync_sub_and_fetch() function when it is specified.

+     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 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.

+JSON-C - A JSON implementation in C <a name="overview"></a>
+-----------------------------------
+
+JSON-C implements a reference counting object model that allows you to easily
+construct JSON objects in C, output them as JSON formatted strings and parse
+JSON formatted strings back into the C representation of JSON objects.
+It aims to conform to [RFC 7159](https://tools.ietf.org/html/rfc7159).
+
+Skip down to [Using json-c](#using)
+or check out the [API docs](https://json-c.github.io/json-c/),
+if you already have json-c installed and ready to use.
+

+
+Building on Unix with `git`, `gcc` and `cmake` <a name="buildunix"></a>
+--------------------------------------------------
+
+If you already have json-c installed, see [Linking to `libjson-c`](#linking)
+for how to build and link your program against it.
+
+### Prerequisites: <a name="installprereq"></a>
+
+ - `gcc`, `clang`, or another C compiler
+
+ - `cmake>=2.8`, `>=3.16` recommended, `cmake=>3.1` for tests
+
+To generate docs you'll also need:
+ - `doxygen>=1.8.13`
+
+If you are on a relatively modern system, you'll likely be able to install
+the prerequisites using your OS's packaging system.
+
+### Install using apt (e.g. Ubuntu 16.04.2 LTS)
+```sh
+sudo apt install git
+sudo apt install cmake
+sudo apt install doxygen  # optional
+sudo apt install valgrind # optional
+```
+
+### Build instructions:  <a name="buildcmds"></a>
+
+`json-c` GitHub repo: https://github.com/json-c/json-c
+
+```sh
+$ git clone https://github.com/json-c/json-c.git
+$ mkdir json-c-build
+$ cd json-c-build
+$ cmake ../json-c   # See CMake section below for custom arguments
+```
+
+Note: it's also possible to put your build directory inside the json-c
+source directory, or even not use a separate build directory at all, but
+certain things might not work quite right (notably, `make distcheck`)
+
+Then:
+
+```sh
+$ make
+$ make test
+$ make USE_VALGRIND=0 test   # optionally skip using valgrind
+$ make install
+```
+
+
+### Generating documentation with Doxygen:
+
+The library documentation can be generated directly from the source code using Doxygen tool:
+
+```sh
+# in build directory
+make doc
+google-chrome doc/html/index.html
+```
+
+
+CMake Options <a name="CMake"></a>
+--------------------
+
+The json-c library is built with [CMake](https://cmake.org/cmake-tutorial/),
+which can take a few options.
+
+Variable                     | Type   | Description
+-----------------------------|--------|--------------
+CMAKE_INSTALL_PREFIX         | String | The install location.
+CMAKE_BUILD_TYPE             | String | Defaults to "debug".
+BUILD_SHARED_LIBS            | Bool   | The default build generates a dynamic (dll/so) library.  Set this to OFF to create a static library only.
+BUILD_STATIC_LIBS            | Bool   | The default build generates a static (lib/a) library.  Set this to OFF to create a shared library only.
+DISABLE_STATIC_FPIC          | Bool   | The default builds position independent code.  Set this to OFF to create a shared library only.
+DISABLE_BSYMBOLIC            | Bool   | Disable use of -Bsymbolic-functions.
+DISABLE_THREAD_LOCAL_STORAGE | Bool   | Disable use of Thread-Local Storage (HAVE___THREAD).
+DISABLE_WERROR               | Bool   | Disable use of -Werror.
+ENABLE_RDRAND                | Bool   | Enable RDRAND Hardware RNG Hash Seed.
+ENABLE_THREADING             | Bool   | Enable partial threading support.
+OVERRIDE_GET_RANDOM_SEED     | String | A block of code to use instead of the default implementation of json_c_get_random_seed(), e.g. on embedded platforms where not even the fallback to time() works.  Must be a single line.
+
+Pass these options as `-D` on CMake's command-line.
+
+```sh
+# build a static library only
+cmake -DBUILD_SHARED_LIBS=OFF ..
+```
+
+### Building with partial threading support
+
+Although json-c does not support fully multi-threaded access to
+object trees, it has some code to help make its use in threaded programs
+a bit safer.  Currently, this is limited to using atomic operations for
+json_object_get() and json_object_put().
+
+Since this may have a performance impact, of at least 3x slower
+according to https://stackoverflow.com/a/11609063, it is disabled by
+default.  You may turn it on by adjusting your cmake command with:
+   -DENABLE_THREADING=ON
+
+Separately, the default hash function used for object field keys,
+lh_char_hash, uses a compare-and-swap operation to ensure the random
+seed is only generated once.  Because this is a one-time operation, it
+is always compiled in when the compare-and-swap operation is available.
+
+
+### cmake-configure wrapper script
+
+For those familiar with the old autoconf/autogen.sh/configure method,
+there is a `cmake-configure` wrapper script to ease the transition to cmake.
+
+```sh
+mkdir build
+cd build
+../cmake-configure --prefix=/some/install/path
+make
+```
+
+cmake-configure can take a few options.
+
+| options | Description|
+| ---- | ---- |
+| prefix=PREFIX |  install architecture-independent files in PREFIX |
+| enable-threading |  Enable code to support partly multi-threaded use |
+| enable-rdrand | Enable RDRAND Hardware RNG Hash Seed generation on supported x86/x64 platforms. |
+| enable-shared  |  build shared libraries [default=yes] |
+| enable-static  |  build static libraries [default=yes] |
+| disable-Bsymbolic |  Avoid linking with -Bsymbolic-function |
+| disable-werror |  Avoid treating compiler warnings as fatal errors |
+
+
+Testing:  <a name="testing"></a>
+----------
+
+By default, if valgrind is available running tests uses it.
+That can slow the tests down considerably, so to disable it use:
+```sh
+export USE_VALGRIND=0
+```
+
+To run tests a separate build directory is recommended:
+```sh
+mkdir build-test
+cd build-test
+# VALGRIND=1 causes -DVALGRIND=1 to be passed when compiling code
+# which uses slightly slower, but valgrind-safe code.
+VALGRIND=1 cmake ..
+make
+
+make test
+# By default, if valgrind is available running tests uses it.
+make USE_VALGRIND=0 test   # optionally skip using valgrind
+```
+
+If a test fails, check `Testing/Temporary/LastTest.log`,
+`tests/testSubDir/${testname}/${testname}.vg.out`, and other similar files.
+If there is insufficient output try:
+```sh
+VERBOSE=1 CTEST_OUTPUT_ON_FAILURE=1 make test
+```
+or
+```sh
+JSONC_TEST_TRACE=1 make test
+```
+and check the log files again.
+
+
+Building on Unix and Windows with `vcpkg` <a name="buildvcpkg"></a>
+--------------------------------------------------
+
+You can download and install JSON-C using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager:
+
+    git clone https://github.com/Microsoft/vcpkg.git
+    cd vcpkg
+    ./bootstrap-vcpkg.sh
+    ./vcpkg integrate install
+    vcpkg install json-c
+
+The JSON-C port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
+
+
+Linking to `libjson-c` <a name="linking">
+----------------------
+
+If your system has `pkgconfig`,
+then you can just add this to your `makefile`:
+
+```make
+CFLAGS += $(shell pkg-config --cflags json-c)
+LDFLAGS += $(shell pkg-config --libs json-c)
+```
+
+Without `pkgconfig`, you might do something like this:
+
+```make
+JSON_C_DIR=/path/to/json_c/install
+CFLAGS += -I$(JSON_C_DIR)/include/json-c
+# Or to use lines like: #include <json-c/json_object.h>
+#CFLAGS += -I$(JSON_C_DIR)/include
+LDFLAGS+= -L$(JSON_C_DIR)/lib -ljson-c
+```
+
+If your project uses cmake:
+
+* Add to your CMakeLists.txt file:
+
+```cmake
+find_package(json-c CONFIG)
+target_link_libraries(${PROJECT_NAME} PRIVATE json-c::json-c)
+```
+
+* Then you might run in your project:
+
+```sh
+cd build
+cmake -DCMAKE_PREFIX_PATH=/path/to/json_c/install/lib64/cmake ..
+```
+
+Using json-c <a name="using">
+------------
+
+To use json-c you can either include json.h, or preferably, one of the
+following more specific header files:
+
+* json_object.h  - Core types and methods.
+* json_tokener.h - Methods for parsing and serializing json-c object trees.
+* json_pointer.h - JSON Pointer (RFC 6901) implementation for retrieving
+                   objects from a json-c object tree.
+* json_object_iterator.h - Methods for iterating over single json_object instances.  (See also `json_object_object_foreach()` in json_object.h)
+* json_visit.h   - Methods for walking a tree of json-c objects.
+* json_util.h    - Miscellaneous utility functions.
+
+For a full list of headers see [files.html](https://json-c.github.io/json-c/json-c-current-release/doc/html/files.html)
+
+The primary type in json-c is json_object.  It describes a reference counted
+tree of json objects which are created by either parsing text with a
+json_tokener (i.e. `json_tokener_parse_ex()`), or by creating
+(with `json_object_new_object()`, `json_object_new_int()`, etc...) and adding
+(with `json_object_object_add()`, `json_object_array_add()`, etc...) them 
+individually.
+Typically, every object in the tree will have one reference, from its parent.
+When you are done with the tree of objects, you call json_object_put() on just
+the root object to free it, which recurses down through any child objects
+calling json_object_put() on each one of those in turn.
+
+You can get a reference to a single child 
+(`json_object_object_get()` or `json_object_array_get_idx()`)
+and use that object as long as its parent is valid.  
+If you need a child object to live longer than its parent, you can
+increment the child's refcount (`json_object_get()`) to allow it to survive
+the parent being freed or it being removed from its parent
+(`json_object_object_del()` or `json_object_array_del_idx()`)
+
+When parsing text, the json_tokener object is independent from the json_object
+that it returns.  It can be allocated (`json_tokener_new()`)
+used one or multiple times (`json_tokener_parse_ex()`, and
+freed (`json_tokener_free()`) while the json_object objects live on.
+
+A json_object tree can be serialized back into a string with 
+`json_object_to_json_string_ext()`.  The string that is returned 
+is only valid until the next "to_json_string" call on that same object.
+Also, it is freed when the json_object is freed.

+# Release checklist:
+
+## Pre-release tasks
+
+* Figure out whether a release is worthwhile to do.
+* Analyze the previous release branch to see if anything should have been
+  applied to master.
+* Collect changes and assemble tentative release notes.
+    * Identify previous release branch point
+    * Check commit logs between previous branch point and now for
+       notable changes worth mentioning
+    * Create a new issues_closed_for_X.Y.md file
+        * Include notable entries from here in the release notes.
+    * Analyze APIs between previous release branch and master to produce list of
+      changes (added/removed/updated funcs, etc...), and detect backwards compat
+      issues.
+        * https://github.com/lvc/abi-compliance-checker
+        * If the new release is not backwards compatible, then this is a MAJOR release.
+        * Mention removed features in ChangeLog
+		* Consider re-adding backwards compatible support, through symbol
+		  aliases and appropriate entries in json-c.sym
+		* Be sure any new symbols are listed in json-c.sym as part of
+		  the _new_ release version.
+    * Update the AUTHORS file
+
+        PREV=$(git tag | tail -1)
+        ( git log -r ${PREV}..HEAD | grep Author: | sed -e's/Author: //' ; cat AUTHORS ) | sort -u > A1
+        mv A1 AUTHORS
+
+    * Exclude mentioning changes that have already been included in a point 
+      release of the previous release branch.
+
+* Update ChangeLog with relevant notes before branching.
+
+* Check that the compile works on Linux - automatic through Travis
+* Check that the compile works on NetBSD
+* Check that the compile works on Windows - automatic through AppVeyor
+
+## Release creation
+
+Start creating the new release:
+    release=0.16
+    git clone https://github.com/json-c/json-c json-c-${release}
+
+    mkdir distcheck
+    cd distcheck
+    # Note, the build directory *must* be entirely separate from
+    # the source tree for distcheck to work properly.
+    cmake -DCMAKE_BUILD_TYPE=Release ../json-c-${release}
+    make distcheck
+    cd ..
+
+Make any fixes/changes *before* branching.
+
+    cd json-c-${release}
+    git branch json-c-${release}
+    git checkout json-c-${release}
+
+------------
+
+Using ${release}:
+	Update the version in json_c_version.h
+	Update the version in CMakeLists.txt (VERSION in the project(...) line)
+
+Update the set_target_properties() line in CmakeLists.txt to set the shared
+library version.  Generally, unless we're doing a major release, change:
+	VERSION x.y.z
+to
+	VERSION x.y+1.z
+
+    git commit -a -m "Bump version to ${release}"
+
+If we're doing a major release (SONAME bump), also bump the version
+ of ALL symbols in json-c.sym.
+ See explanation at https://github.com/json-c/json-c/issues/621
+ More info at: https://software.intel.com/sites/default/files/m/a/1/e/dsohowto.pdf
+
+------------
+
+Generate the doxygen documentation:
+
+    (cd ../distcheck && make doc)
+    cp -r -p ../distcheck/doc/{html,Doxyfile} doc/.
+	rm doc/Doxyfile   # Remove generated file w/ hardcoded paths
+    git add -f doc
+    git commit doc -m "Generate docs for the ${release} release"
+
+------------
+
+Create the release tarballs:
+
+    cd ..
+    echo .git > excludes
+    tar -czf json-c-${release}.tar.gz -X excludes json-c-${release}
+
+    echo 'doc/*' >> excludes
+    tar -czf json-c-${release}-nodoc.tar.gz -X excludes json-c-${release}
+
+------------
+
+Tag the branch:
+
+    cd json-c-${release}
+    git tag -a json-c-${release}-$(date +%Y%m%d) -m "Release json-c-${release}"
+
+    git push origin json-c-${release}
+    git push --tags
+
+------------
+
+Go to Amazon S3 service at:
+    https://console.aws.amazon.com/s3/
+
+Upload the two tarballs in the json-c_releases/releases folder.
+	When uploading, use "Standard" storage class, and make the uploaded files publicly accessible.
+
+Logout of Amazon S3, and verify that the files are visible.
+    https://s3.amazonaws.com/json-c_releases/releases/index.html
+
+===================================
+
+Post-release checklist:
+
+    git checkout master
+
+Add new section to ChangeLog for ${release}+1
+
+Use ${release}.99 to indicate a version "newer" than anything on the branch:
+	Update the version in json_c_version.h
+	Update the version in CMakeLists.txt
+
+Update RELEASE_CHECKLIST.txt, set release=${release}+1
+
+Add a new empty section to the json-c.sym file, for ${release}+1
+
+Update the set_target_properties() line in CmakeLists.txt to match the release branch.
+
+    git commit -a -m "Update the master branch to version ${release}.99"
+    git push
+
+------------
+
+Update the gh-pages branch with new docs:
+
+    cd json-c-${release}
+    git checkout json-c-${release}
+    cd ..
+
+    git clone -b gh-pages https://github.com/json-c/json-c json-c-pages
+    cd json-c-pages
+    mkdir json-c-${release}
+    cp -R ../json-c-${release}/doc json-c-${release}/.
+    git add json-c-${release}
+    rm json-c-current-release
+    ln -s json-c-${release} json-c-current-release
+    git commit -a -m "Add the ${release} docs."
+
+    vi index.html
+    # Add/change links to current release.
+
+    git commit -a -m "Update the doc links to point at ${release}"
+
+    git push
+
+------------
+
+Update checksums on wiki page.
+
+    cd ..
+    openssl sha -sha256 json-c*gz
+    openssl md5 json-c*gz
+
+Copy and paste this output into the wiki page at:
+	https://github.com/json-c/json-c/wiki
+
+------------
+
+Send an email to the mailing list.

+In general:
+For minor changes to a function, copy the existing formatting.
+When changing the style, commit that separately from other changes.
+For new code and major changes to a function, switch to the official json-c style.
+
+Official json-c style:
+
+Aim for readability, not strict conformance to fixed style rules.
+Formatting is tab based; previous attempts at proper alignment with
+spaces for continuation lines have been abandoned in favor of the
+convenience of using clang-format.
+Refer to the .clang-format file for details, and run the tool before commit:
+
+    clang-format -i somefile.c foo.h
+
+For sections of code that would be significantly negatively impacted, surround
+them with magic comments to disable formatting:
+
+    /* clang-format off */
+    ...code...
+    /* clang-format on */
+
+
+Naming:
+Words within function and variable names are separated with underscores.  Avoid camel case.
+Prefer longer, more descriptive names, but not excessively so.  No single letter variable names.
+
+Other:
+Variables should be defined for the smallest scope needed.
+Functions should be defined static when possible.
+When possible, avoid exposing internals in the public API.

+Benchmark tests for json-c
+
+General strategy:
+-------------------
+
+* Identify "after" commit hash
+    * Use provided directory
+    * Use provided commit hash
+    * Local changes in current working directory
+    * ${cur_branch}
+* Identify "before" commit hash, in order of preference
+    * Use provided directory
+    * Use provided commit hash
+    * Use origin/${cur_branch}, if different from ${after_commit}
+    * Use previous release
+
+* If not using existing dir, clone to src-${after_commit}
+    * or, checkout appropriate commit in existing src-${after_commit}
+* Create build & install dirs for ${after_commit}
+* Build & install ${after_commit}
+* Compile benchmark programs against install-${after_commit}
+
+* If not using existing dir, clone to src-${before_commit}
+    * or, checkout appropriate commit in existing src-${before_commit}
+* Create build & install dirs for ${before_commit}
+* Build & install ${before_commit}
+* Compile benchmark programs against install-${before_commit}
+
+* Run benchmark in each location
+* Compare results
+
+heaptrack memory profiler
+---------------------------
+
+https://milianw.de/blog/heaptrack-a-heap-memory-profiler-for-linux.html
+
+
+```
+yum install libdwarf-devel elfutils boost-devel libunwind-devel
+
+git clone git://anongit.kde.org/heaptrack
+cd heaptrack
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo \
+	-DCMAKE_INSTALL_PREFIX=$HOME/heaptrack-install ..
+make install
+```
+
+
+Issues
+--------
+
+* jc-bench.sh is incomplete.
+
+* valgrind massif misreports "extra-heap" bytes?
+
+    "json_parse -n canada.json" shows 38640 KB maxrss.
+
+    Using valgrind --tool=massif, a large amount of memory is listed as
+     wasted "extra-heap" bytes.  (~5.6MB)
+
+    ```
+    valgrind --tool=massif --massif-out-file=massif.out ./json_parse -n ~/canada.json
+    ms_print massif.out
+    ```
+
+
+    Using heaptrack, and analyzing the histogram, only shows ~2.6MB
+    ```
+    heaptrack ./json_parse -n canada.json
+    heaptrack --analyze heaptrack*gz -H histogram.out
+    awk ' { s=$1; count=$2; ru=(int((s+ 15) / 16)) * 16; wasted = ((ru-s)*count); print s, count, ru-s, wasted; total=total+wasted} END { print "Total: ", total }' histogram.out
+    ```
+
+ With the (unreleased) arraylist trimming changes, maxrss reported by
+  getrusage() goes down, but massif claims *more* total usage, and a HUGE 
+  extra-heap amount (50% of total).

+/**
+ * How It Works
+ *
+ * For each JSON Object, json-c maintains a linked list of zero
+ * or more lh_entry (link-hash entry) structures inside the
+ * Object's link-hash table (lh_table).
+ *
+ * Each lh_entry structure on the JSON Object's linked list
+ * represents a single name/value pair.  The "next" field of the
+ * last lh_entry in the list is set to NULL, which terminates
+ * the list.
+ *
+ * We represent a valid iterator that refers to an actual
+ * name/value pair via a pointer to the pair's lh_entry
+ * structure set as the iterator's opaque_ field.
+ *
+ * We follow json-c's current pair list representation by
+ * representing a valid "end" iterator (one that refers past the
+ * last pair) with a NULL value in the iterator's opaque_ field.
+ *
+ * A JSON Object without any pairs in it will have the "head"
+ * field of its lh_table structure set to NULL.  For such an
+ * object, json_object_iter_begin will return an iterator with
+ * the opaque_ field set to NULL, which is equivalent to the
+ * "end" iterator.
+ *
+ * When iterating, we simply update the iterator's opaque_ field
+ * to point to the next lh_entry structure in the linked list.
+ * opaque_ will become NULL once we iterate past the last pair
+ * in the list, which makes the iterator equivalent to the "end"
+ * iterator.

+ *   https://tools.ietf.org/html/rfc6901
+ *
+ * Note that 'obj' is a double pointer, mostly for the "" (empty string)
+ * case, where the entire JSON object would be replaced by 'value'.
+ * In the case of the "" path, the object at '*obj' will have it's refcount
+ * decremented with 'json_object_put()' and the 'value' object will be assigned to it.
+ *
+ * For other cases (JSON sub-objects) ownership of 'value' will be transferred into
+ * '*obj' via 'json_object_object_add()' & 'json_object_array_put_idx()', so the
+ * only time the refcount should be decremented for 'value' is when the return value of
+ * 'json_pointer_set()' is negative (meaning the 'value' object did not get set into '*obj').
+ *
+ * That also implies that 'json_pointer_set()' does not do any refcount incrementing.
+ * (Just that single decrement that was mentioned above).

+/**
+ * Parse a string and return a non-NULL json_object if a valid JSON value
+ * is found.  The string does not need to be a JSON object or array;
+ * it can also be a string, number or boolean value.
+ *
+ * A partial JSON string can be parsed.  If the parsing is incomplete,
+ * NULL will be returned and json_tokener_get_error() will return
+ * json_tokener_continue.
+ * json_tokener_parse_ex() can then be called with additional bytes in str
+ * to continue the parsing.
+ *
+ * If json_tokener_parse_ex() returns NULL and the error is anything other than
+ * json_tokener_continue, a fatal error has occurred and parsing must be
+ * halted.  Then, the tok object must not be reused until json_tokener_reset()
+ * is called.
+ *
+ * When a valid JSON value is parsed, a non-NULL json_object will be
+ * returned, with a reference count of one which belongs to the caller.  Also,
+ * json_tokener_get_error() will return json_tokener_success. Be sure to check
+ * the type with json_object_is_type() or json_object_get_type() before using
+ * the object.
+ *
+ * Trailing characters after the parsed value do not automatically cause an
+ * error.  It is up to the caller to decide whether to treat this as an
+ * error or to handle the additional characters, perhaps by parsing another
+ * json value starting from that point.
+ *
+ * If the caller knows that they are at the end of their input, the length
+ * passed MUST include the final '\0' character, so values with no inherent
+ * end (i.e. numbers) can be properly parsed, rather than just returning
+ * json_tokener_continue.
+ *
+ * Extra characters can be detected by comparing the value returned by
+ * json_tokener_get_parse_end() against
+ * the length of the last len parameter passed in.
+ *
+ * The tokener does \b not maintain an internal buffer so the caller is
+ * responsible for a subsequent call to json_tokener_parse_ex with an 
+ * appropriate str parameter starting with the extra characters.
+ *
+ * This interface is presently not 64-bit clean due to the int len argument
+ * so the function limits the maximum string size to INT32_MAX (2GB).
+ * If the function is called with len == -1 then strlen is called to check
+ * the string length is less than INT32_MAX (2GB)
+ *
+ * Example:
+ * @code
+json_object *jobj = NULL;
+const char *mystring = NULL;
+int stringlen = 0;
+enum json_tokener_error jerr;
+do {
+	mystring = ...  // get JSON string, e.g. read from file, etc...
+	stringlen = strlen(mystring);
+	if (end_of_input)
+		stringlen++;  // Include the '\0' if we know we're at the end of input
+	jobj = json_tokener_parse_ex(tok, mystring, stringlen);
+} while ((jerr = json_tokener_get_error(tok)) == json_tokener_continue);
+if (jerr != json_tokener_success)
+{
+	fprintf(stderr, "Error: %s\n", json_tokener_error_desc(jerr));
+	// Handle errors, as appropriate for your application.
+}
+if (json_tokener_get_parse_end(tok) < stringlen)
+{
+	// Handle extra characters after parsed object as desired.
+	// e.g. issue an error, parse another object from that point, etc...
+}
+// Success, use jobj here.

+lookup3.c, by Bob Jenkins, May 2006, Public Domain.
+
+These are functions for producing 32-bit hashes for hash table lookup.
+hashword(), hashlittle(), hashlittle2(), hashbig(), mix(), and final()
+are externally useful functions.  Routines to test the hash are included
+if SELF_TEST is defined.  You can use this free for any purpose.  It's in
+the public domain.  It has no warranty.
+
+You probably want to use hashlittle().  hashlittle() and hashbig()
+hash byte arrays.  hashlittle() is faster than hashbig() on
+little-endian machines.  Intel and AMD are little-endian machines.
+On second thought, you probably want hashlittle2(), which is identical to
+hashlittle() except it returns two 32-bit hashes for the price of one.
+You could implement hashbig2() if you wanted but I haven't bothered here.
+
+If you want to find a hash of, say, exactly 7 integers, do
+  a = i1;  b = i2;  c = i3;
+  mix(a,b,c);
+  a += i4; b += i5; c += i6;
+  mix(a,b,c);
+  a += i7;
+  final(a,b,c);
+then use c as the hash value.  If you have a variable length array of
+4-byte integers to hash, use hashword().  If you have a byte array (like
+a character string), use hashlittle().  If you have several byte arrays, or
+a mix of things, see the comments above hashlittle().
+
+Why is this so big?  I read 12 bytes at a time into 3 4-byte integers,
+then mix those integers.  This is fast (you can do a lot more thorough
+mixing with 12*3 instructions on 3 integers than you can with 3 instructions
+on 1 byte), but shoehorning those bytes into integers efficiently is messy.

+mix -- mix 3 32-bit values reversibly.
+
+This is reversible, so any information in (a,b,c) before mix() is
+still in (a,b,c) after mix().
+
+If four pairs of (a,b,c) inputs are run through mix(), or through
+mix() in reverse, there are at least 32 bits of the output that
+are sometimes the same for one pair and different for another pair.
+This was tested for:
+* pairs that differed by one bit, by two bits, in any combination
+  of top bits of (a,b,c), or in any combination of bottom bits of
+  (a,b,c).
+* "differ" is defined as +, -, ^, or ~^.  For + and -, I transformed
+  the output delta to a Gray code (a^(a>>1)) so a string of 1's (as
+  is commonly produced by subtraction) look like a single 1-bit
+  difference.
+* the base values were pseudorandom, all zero but one bit set, or
+  all zero plus a counter that starts at zero.
+
+Some k values for my "a-=c; a^=rot(c,k); c+=b;" arrangement that
+satisfy this are
+    4  6  8 16 19  4
+    9 15  3 18 27 15
+   14  9  3  7 17  3
+Well, "9 15 3 18 27 15" didn't quite get 32 bits diffing
+for "differ" defined as + with a one-bit base and a two-bit delta.  I
+used https://burtleburtle.net/bob/hash/avalanche.html to choose
+the operations, constants, and arrangements of the variables.
+
+This does not achieve avalanche.  There are input bits of (a,b,c)
+that fail to affect some output bits of (a,b,c), especially of a.  The
+most thoroughly mixed value is c, but it doesn't really even achieve
+avalanche in c.
+
+This allows some parallelism.  Read-after-writes are good at doubling
+the number of bits affected, so the goal of mixing pulls in the opposite
+direction as the goal of parallelism.  I did what I could.  Rotates
+seem to cost as much as shifts on every machine I could lay my hands
+on, and rotates are much kinder to the top and bottom bits, so I used
+rotates.
