+Contribution Guidelines
+=======================
+
+Contributions to cJSON are welcome. If you find a bug or want to improve cJSON in another way, pull requests are appreciated.
+
+For bigger changes, in order to avoid wasted effort, please open an issue to discuss the technical details before creating a pull request.
+
+The further sections explain the process in more detail and provides some guidelines on how contributions should look like.
+
+Branches
+--------
+There are two branches to be aware of, the `master` and the `develop` branch. The `master` branch is reserved for the latest release, so only make pull requests to the `master` branch for small bug- or security fixes (these are usually just a few lines). In all other cases, please make a pull request to the `develop` branch.
+
+Coding Style
+------------
+The coding style has been discussed in [#24](https://github.com/DaveGamble/cJSON/issues/24). The basics are:
+
+* Use 4 tabs for indentation
+* No oneliners (conditions, loops, variable declarations ...)
+* Always use parenthesis for control structures
+* Don't implicitly rely on operator precedence, use round brackets in expressions. e.g. `(a > b) && (c < d)` instead of `a>b && c<d`
+* opening curly braces start in the next line
+* use spaces around operators
+* lines should not have trailing whitespace
+* use spaces between function parameters
+* use pronouncable variable names, not just a combination of letters
+
+Example:
+
+```c
+/* calculate the new length of the string in a printbuffer and update the offset */
+static void update_offset(printbuffer * const buffer)
+{
+    const unsigned char *buffer_pointer = NULL;
+    if ((buffer == NULL) || (buffer->buffer == NULL))
+    {
+        return;
+    }
+    buffer_pointer = buffer->buffer + buffer->offset;
+
+    buffer->offset += strlen((const char*)buffer_pointer);
+}
+```
+
+Unit Tests
+----------
+cJSON uses the [Unity](https://github.com/ThrowTheSwitch/Unity) library for unit tests. The tests are located in the `tests` directory. In order to add a new test, either add it to one of the existing files (if it fits) or add a new C file for the test. That new file has to be added to the list of tests in `tests/CMakeLists.txt`.
+
+All new features have to be covered by unit tests.
+
+Other Notes
+-----------
+* Internal functions are to be declared static.
+* Wrap the return type of external function in the `CJSON_PUBLIC` macro.

+1.3.2
+=====
+Fix:
+----
+- Don't build the unity library if testing is disabled ( #121 ). Thanks @ffontaine
+
+1.3.1
+=====
+Bugfix release that fixes an out of bounds read #118. This shouldn't have any security implications.
+
+1.3.0
+=====
+This release includes a lot of rework in the parser and includes the Cunity unit testing framework, as well as some fixes. I increased the minor version number because there were quite a lot of internal changes.
+
+Features:
+---------
+- New type for cJSON structs: `cJSON_Invalid` (#108)
+
+Fixes:
+------
+- runtime checks for a lot of potential integer overflows
+- fix incorrect return in cJSON_PrintBuffered (cf9d57d56cac21fc59465b8d26cf29bf6d2a87b3)
+- fix several potential issues found by [Coverity](https://scan.coverity.com/projects/cjson)
+- fix potentially undefined behavior when assigning big numbers to `valueint` (41e2837df1b1091643aff073f2313f6ff3cc10f4)
+  - Numbers exceeding `INT_MAX` or lower than `INT_MIN` will be explicitly assigned to `valueint` as `INT_MAX` and `INT_MIN` respectively (saturation on overflow).
+  - fix the `cJSON_SetNumberValue` macro (87f77274de6b3af00fb9b9a7f3b900ef382296c2), this slightly changes the behavior, see commit message
+
+Introduce unit tests
+--------------------
+
+Started writing unit tests with the [Cunity](https://github.com/ThrowTheSwitch/Unity) testing framework. Currently this covers the parser functions.
+
+Also:
+- Support for running the tests with [Valgrind](http://valgrind.org)
+- Support for compiling the tests with [AddressSanitizer](https://github.com/google/sanitizers) and [UndefinedBehaviorSanitizer](https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html).
+- `travis.yml` file for running unit tests on travis. (not enabled for the repository yet though #102)
+
+Simplifications
+---------------
+
+After having unit tests for the parser function in place, I started refactoring the parser functions (as well as others) and making them easier to read and maintain.
+- Use `strtod` from the standard library for parsing numbers (074766997246481dfc72bfa78f07898a2716473f)
+- Use goto-fail in several parser functions (#100)
+- Rewrite/restructure all of the parsing functions to be easier to understand and have less code paths doing the same as another. (#109)
+- Simplify the buffer allocation strategy to always doubling the needed amount (9f6fa94c91a87b71e4c6868dbf2ce431a48517b0)
+- Combined `cJSON_AddItemToObject` and `cJSON_AddItemToObjectCS` to one function (cf862d0fed7f9407e4b046d78d3d8050d2080d12)
+
+Other changes
+-------------
+- Prevent the usage of incompatible C and header versions via preprocessor directive (123bb1af7bfae41d805337fef4b41045ef6c7d25)
+- Let CMake automatically detect compiler flags
+- Add new compiler flags (`-Wundef`, `-Wswitch-default`, `-Wconversion`, `-fstack-protector-strong`) (#98)
+- Change internal sizes from `int` to `size_t` (ecd5678527a6bc422da694e5be9e9979878fe6a0)
+- Change internal strings from `char*` to `unsigned char*` (28b9ba4334e0f7309e867e874a31f395c0ac2474)
+- Add `const` in more places
+
+1.2.1
+=====
+Fixes:
+------
+- Fixes a potential null pointer dereference in cJSON_Utils, discovered using clang's static analyzer by @bnason-nf (#96)
+
+1.2.0
+=====
+Features:
+---------
+- Add a new type of cJSON item for raw JSON and support printing it. Thanks @loigu (#65, #90)
+
+Fixes:
+------
+- Compiler warning if const is casted away, Thanks @gatzka (#83)
+- Fix compile error with strict-overflow on PowerPC, (#85)
+- Fix typo in the README, thanks @MicroJoe (#88)
+- Add compile flag for compatibility with C++ compilers
+
+1.1.0
+=====
+- Add a function `cJSON_PrintPreallocated` to print to a preallocated buffer, thanks @ChisholmKyle (#72)
+- More compiler warnings when using Clang or GCC, thanks @gatzka (#75, #78)
+- fixed a memory leak in `cJSON_Duplicate`, thanks @alperakcan (#81)
+- fix the `ENABLE_CUSTOM_COMPILER_FLAGS` cmake option
+
+1.0.2
+=====
+Rename internal boolean type, see #71.
+
+1.0.1
+=====
+Small bugfix release.
+- Fixes a bug with the use of the cJSON structs type in cJSON_Utils, see d47339e2740360e6e0994527d5e4752007480f3a
+- improve code readability
+- initialize all variables
+
+1.0.0
+=====
+This is the first official versioned release of cJSON. It provides an API version for the shared library and improved Makefile and CMake build files.

And it installs CMake config files, that can be used by other CMake based projects to discover the library.

+### Caveats
+
+#### Zero Character
+
+cJSON doesn't support strings that contain the zero character `'\0'` or `\u0000`. This is impossible with the current API because strings are zero terminated.
+
+#### Character Encoding
+
+cJSON only supports UTF-8 encoded input. In most cases it doesn't reject invalid UTF-8 as input though, it just propagates it through as is. As long as the input doesn't contain invalid UTF-8, the output will always be valid UTF-8.
+
+#### C Standard
+
+cJSON is written in ANSI C (or C89, C90). If your compiler or C library doesn't follow this standard, correct behavior is not guaranteed.
+
+NOTE: ANSI C is not C++ therefore it shouldn't be compiled with a C++ compiler. You can compile it with a C compiler and link it with your C++ code however. Although compiling with a C++ compiler might work, correct behavior is not guaranteed.
+
+#### Floating Point Numbers
+
+cJSON does not officially support any `double` implementations other than IEEE754 double precision floating point numbers. It might still work with other implementations but bugs with these will be considered invalid.
+
+The maximum length of a floating point literal that cJSON supports is currently 63 characters.
+
+#### Deep Nesting Of Arrays And Objects
+
+cJSON doesn't support arrays and objects that are nested too deeply because this would result in a stack overflow. To prevent this cJSON limits the depth to `CJSON_NESTING_LIMIT` which is 1000 by default but can be changed at compile time.
+
+#### Thread Safety
+
+In general cJSON is **not thread safe**.
+
+However it is thread safe under the following conditions:
+* `cJSON_GetErrorPtr` is never used (the `return_parse_end` parameter of `cJSON_ParseWithOpts` can be used instead)
+* `cJSON_InitHooks` is only ever called before using cJSON in any threads.
+* `setlocale` is never called before all calls to cJSON functions have returned.
+
+#### Case Sensitivity
+
+When cJSON was originally created, it didn't follow the JSON standard and didn't make a distinction between uppercase and lowercase letters. If you want the correct, standard compliant, behavior, you need to use the `CaseSensitive` functions where available.

+JSON Patch Tests
+================
+
+These are test cases for implementations of [IETF JSON Patch (RFC6902)](http://tools.ietf.org/html/rfc6902).
+
+Some implementations can be found at [jsonpatch.com](http://jsonpatch.com).
+
+
+Test Format
+-----------
+
+Each test file is a JSON document that contains an array of test records. A
+test record is an object with the following members:
+
+- doc: The JSON document to test against
+- patch: The patch(es) to apply
+- expected: The expected resulting document, OR
+- error: A string describing an expected error
+- comment: A string describing the test
+- disabled: True if the test should be skipped
+
+All fields except 'doc' and 'patch' are optional. Test records consisting only
+of a comment are also OK.
+
+
+Files
+-----
+
+- tests.json: the main test file
+- spec_tests.json: tests from the RFC6902 spec
+
+
+Writing Tests
+-------------
+
+All tests should have a descriptive comment.  Tests should be as
+simple as possible - just what's required to test a specific piece of
+behavior.  If you want to test interacting behaviors, create tests for
+each behavior as well as the interaction.
+
+If an 'error' member is specified, the error text should describe the
+error the implementation should raise - *not* what's being tested.
+Implementation error strings will vary, but the suggested error should
+be easily matched to the implementation error string.  Try to avoid
+creating error tests that might pass because an incorrect error was
+reported.
+
+Please feel free to contribute!
+
+
+Credits
+-------
+
+The seed test set was adapted from Byron Ruth's
+[jsonpatch-js](https://github.com/bruth/jsonpatch-js/blob/master/test.js) and
+extended by [Mike McCabe](https://github.com/mikemccabe).

+Unity Test API
+==============
+
+[![Unity Build Status](https://api.travis-ci.org/ThrowTheSwitch/Unity.png?branch=master)](https://travis-ci.org/ThrowTheSwitch/Unity)
+__Copyright (c) 2007 - 2017 Unity Project by Mike Karlesky, Mark VanderVoord, and Greg Williams__
+
+Running Tests
+-------------
+
+    RUN_TEST(func, linenum)
+
+Each Test is run within the macro `RUN_TEST`.  This macro performs necessary setup before the test is called and handles cleanup and result tabulation afterwards.
+
+Ignoring Tests
+--------------
+
+There are times when a test is incomplete or not valid for some reason.  At these times, TEST_IGNORE can be called.  Control will immediately be returned to the caller of the test, and no failures will be returned.
+
+    TEST_IGNORE()
+
+Ignore this test and return immediately
+
+    TEST_IGNORE_MESSAGE (message)
+
+Ignore this test and return immediately.  Output a message stating why the test was ignored.
+
+Aborting Tests
+--------------
+
+There are times when a test will contain an infinite loop on error conditions, or there may be reason to escape from the test early without executing the rest of the test.  A pair of macros support this functionality in Unity.  The first `TEST_PROTECT` sets up the feature, and handles emergency abort cases. `TEST_ABORT` can then be used at any time within the tests to return to the last `TEST_PROTECT` call.
+
+    TEST_PROTECT()
+
+Setup and Catch macro
+
+    TEST_ABORT()
+
+Abort Test macro
+
+Example:
+
+    main()
+    {
+        if (TEST_PROTECT())
+        {
+            MyTest();
+        }
+    }
+
+If MyTest calls `TEST_ABORT`, program control will immediately return to `TEST_PROTECT` with a return value of zero.
+
+
+Unity Assertion Summary
+=======================
+
+Basic Validity Tests
+--------------------
+
+    TEST_ASSERT_TRUE(condition)
+
+Evaluates whatever code is in condition and fails if it evaluates to false
+
+    TEST_ASSERT_FALSE(condition)
+
+Evaluates whatever code is in condition and fails if it evaluates to true
+
+    TEST_ASSERT(condition)
+
+Another way of calling `TEST_ASSERT_TRUE`
+
+    TEST_ASSERT_UNLESS(condition)
+
+Another way of calling `TEST_ASSERT_FALSE`
+
+    TEST_FAIL()
+    TEST_FAIL_MESSAGE(message)
+
+This test is automatically marked as a failure.  The message is output stating why.
+
+Numerical Assertions: Integers
+------------------------------
+
+    TEST_ASSERT_EQUAL_INT(expected, actual)
+    TEST_ASSERT_EQUAL_INT8(expected, actual)
+    TEST_ASSERT_EQUAL_INT16(expected, actual)
+    TEST_ASSERT_EQUAL_INT32(expected, actual)
+    TEST_ASSERT_EQUAL_INT64(expected, actual)
+
+Compare two integers for equality and display errors as signed integers. A cast will be performed
+to your natural integer size so often this can just be used.  When you need to specify the exact size,
+like when comparing arrays, you can use a specific version:
+
+    TEST_ASSERT_EQUAL_UINT(expected, actual)
+    TEST_ASSERT_EQUAL_UINT8(expected, actual)
+    TEST_ASSERT_EQUAL_UINT16(expected, actual)
+    TEST_ASSERT_EQUAL_UINT32(expected, actual)
+    TEST_ASSERT_EQUAL_UINT64(expected, actual)
+
+Compare two integers for equality and display errors as unsigned integers.  Like INT, there are
+variants for different sizes also.
+
+    TEST_ASSERT_EQUAL_HEX(expected, actual)
+    TEST_ASSERT_EQUAL_HEX8(expected, actual)
+    TEST_ASSERT_EQUAL_HEX16(expected, actual)
+    TEST_ASSERT_EQUAL_HEX32(expected, actual)
+    TEST_ASSERT_EQUAL_HEX64(expected, actual)
+
+Compares two integers for equality and display errors as hexadecimal.  Like the other integer comparisons,
+you can specify the size... here the size will also effect how many nibbles are shown (for example, `HEX16`
+will show 4 nibbles).
+
+    TEST_ASSERT_EQUAL(expected, actual)
+
+Another way of calling TEST_ASSERT_EQUAL_INT
+
+    TEST_ASSERT_INT_WITHIN(delta, expected, actual)
+
+Asserts that the actual value is within plus or minus delta of the expected value.  This also comes in
+size specific variants.
+
+Arrays
+------
+
+    _ARRAY
+
+You can append `_ARRAY` to any of these macros to make an array comparison of that type.  Here you will
+need to care a bit more about the actual size of the value being checked.  You will also specify an
+additional argument which is the number of elements to compare.  For example:
+
+    TEST_ASSERT_EQUAL_HEX8_ARRAY(expected, actual, elements)
+
+    _EACH_EQUAL
+
+Another array comparison option is to check that EVERY element of an array is equal to a single expected
+value. You do this by specifying the EACH_EQUAL macro. For example:
+
+    TEST_ASSERT_EACH_EQUAL_INT32(expected, actual, elements)
+
+Numerical Assertions: Bitwise
+-----------------------------
+
+    TEST_ASSERT_BITS(mask, expected, actual)
+
+Use an integer mask to specify which bits should be compared between two other integers.  High bits in the mask are compared, low bits ignored.
+
+    TEST_ASSERT_BITS_HIGH(mask, actual)
+
+Use an integer mask to specify which bits should be inspected to determine if they are all set high.  High bits in the mask are compared, low bits ignored.
+
+    TEST_ASSERT_BITS_LOW(mask, actual)
+
+Use an integer mask to specify which bits should be inspected to determine if they are all set low.  High bits in the mask are compared, low bits ignored.
+
+    TEST_ASSERT_BIT_HIGH(bit, actual)
+
+Test a single bit and verify that it is high.  The bit is specified 0-31 for a 32-bit integer.
+
+    TEST_ASSERT_BIT_LOW(bit, actual)
+
+Test a single bit and verify that it is low.  The bit is specified 0-31 for a 32-bit integer.
+
+Numerical Assertions: Floats
+----------------------------
+
+    TEST_ASSERT_FLOAT_WITHIN(delta, expected, actual)
+
+Asserts that the actual value is within plus or minus delta of the expected value.
+
+    TEST_ASSERT_EQUAL_FLOAT(expected, actual)
+    TEST_ASSERT_EQUAL_DOUBLE(expected, actual)
+
+Asserts that two floating point values are "equal" within a small % delta of the expected value.
+
+String Assertions
+-----------------
+
+    TEST_ASSERT_EQUAL_STRING(expected, actual)
+
+Compare two null-terminate strings.  Fail if any character is different or if the lengths are different.
+
+    TEST_ASSERT_EQUAL_STRING_LEN(expected, actual, len)
+
+Compare two strings.  Fail if any character is different, stop comparing after len characters.
+
+    TEST_ASSERT_EQUAL_STRING_MESSAGE(expected, actual, message)
+
+Compare two null-terminate strings.  Fail if any character is different or if the lengths are different. Output a custom message on failure.
+
+    TEST_ASSERT_EQUAL_STRING_LEN_MESSAGE(expected, actual, len, message)
+
+Compare two strings.  Fail if any character is different, stop comparing after len characters. Output a custom message on failure.
+
+Pointer Assertions
+------------------
+
+Most pointer operations can be performed by simply using the integer comparisons above.  However, a couple of special cases are added for clarity.
+
+    TEST_ASSERT_NULL(pointer)
+
+Fails if the pointer is not equal to NULL
+
+    TEST_ASSERT_NOT_NULL(pointer)
+
+Fails if the pointer is equal to NULL
+
+Memory Assertions
+-----------------
+
+    TEST_ASSERT_EQUAL_MEMORY(expected, actual, len)
+
+Compare two blocks of memory.  This is a good generic assertion for types that can't be coerced into acting like
+standard types... but since it's a memory compare, you have to be careful that your data types are packed.
+
+_MESSAGE
+--------
+
+you can append _MESSAGE to any of the macros to make them take an additional argument.  This argument
+is a string that will be printed at the end of the failure strings.  This is useful for specifying more
+information about the problem.
