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.
