internal boolean type `cJSON_bool` in the header, see [2d3520e](https://github.com/DaveGamble/cJSON/commit/2d3520e0b9d0eb870e8886e8a21c571eeddbb310) 345 346Fixes 347* Fix handling of NULL pointers in `cJSON_ArrayForEach`, see [b47d0e3](https://github.com/DaveGamble/cJSON/commit/b47d0e34caaef298edfb7bd09a72cfff21d231ff) 348* Make it compile with GCC 7 (fix -Wimplicit-fallthrough warning), see [9d07917](https://github.com/DaveGamble/cJSON/commit/9d07917feb1b613544a7513d19233d4c851ad7ad) 349 350Other Improvements 351* internally use realloc if available ([#110](https://github.com/DaveGamble/cJSON/pull/110)) 352* builtin support for fuzzing with [afl](http://lcamtuf.coredump.cx/afl/) ([#111](https://github.com/DaveGamble/cJSON/pull/111)) 353* unit tests for the print functions ([#112](https://github.com/DaveGamble/cJSON/pull/112)) 354* Always use buffered printing ([#113](https://github.com/DaveGamble/cJSON/pull/113)) 355* simplify the print

357 3581.3.2 (Mar 1, 2017) 359===== 360Fixes: 361------ 362* Don't build the unity library if testing is disabled, see [#121](https://github.com/DaveGamble/cJSON/pull/121). Thanks @ffontaine 363 3641.3.1 (Feb 27, 2017) 365===== 366Fixes: 367------ 368* Bugfix release that fixes an out of bounds read, see [#118](https://github.com/DaveGamble/cJSON/pull/118). This shouldn't have any security implications. 369 3701.3.0 (Feb 17, 2017) 371===== 372This 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. 373 374Features: 375* New type for cJSON structs: `cJSON_Invalid`, see [#108](https://github.com/DaveGamble/cJSON/pull/108) 376 377Fixes: 378------ 379* runtime checks for a lot of potential integer overflows 380* fix incorrect return in cJSON_PrintBuffered [cf9d57d](https://github.com/DaveGamble/cJSON/commit/cf9d57d56cac21fc59465b8d26cf29bf6d2a87b3) 381* fix several potential issues found by [Coverity](https://scan.coverity.com/projects/cjson) 382* fix potentially undefined behavior when assigning big numbers to `valueint` ([41e2837](https://github.com/DaveGamble/cJSON/commit/41e2837df1b1091643aff073f2313f6ff3cc10f4)) 383 * 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). 384 * fix the `cJSON_SetNumberValue` macro ([87f7727](https://github.com/DaveGamble/cJSON/commit/87f77274de6b3af00fb9b9a7f3b900ef382296c2)), this slightly changes the behavior, see commit message 385 386Introduce unit tests 387-------------------- 388 389* Started writing unit tests with the [Cunity](https://github.com/ThrowTheSwitch/Unity) testing framework. Currently this covers the parser functions. 390 391Also: 392* Support for running the tests with [Valgrind](http://valgrind.org) 393* Support for compiling the tests with [AddressSanitizer](https://github.com/google/sanitizers) and [UndefinedBehaviorSanitizer](https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html). 394* `travis.yml` file for running unit tests on travis. (not enabled for the repository yet though [#102](https://github.com/DaveGamble/cJSON/issues/102) 395 396Simplifications 397--------------- 398 399After 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. 400* Use `strtod` from the standard library for parsing numbers ([0747669](https://github.com/DaveGamble/cJSON/commit/074766997246481dfc72bfa78f07898a2716473f)) 401* Use goto-fail in several parser functions ([#100](https://github.com/DaveGamble/cJSON/pull/100)) 402* Rewrite/restructure all of the parsing functions to be easier to understand and have less code paths doing the same as another. ([#109](https://github.com/DaveGamble/cJSON/pull/109)) 403* Simplify the buffer allocation strategy to always doubling the needed amount ([9f6fa94](https://github.com/DaveGamble/cJSON/commit/9f6fa94c91a87b71e4c6868dbf2ce431a48517b0)) 404* Combined `cJSON_AddItemToObject` and `cJSON_AddItemToObjectCS` to one function ([cf862d](https://github.com/DaveGamble/cJSON/commit/cf862d0fed7f9407e4b046d78d3d8050d2080d12)) 405 406Other changes 407------------- 408* Prevent the usage of incompatible C and header versions via preprocessor directive ([123bb1](https://github.com/DaveGamble/cJSON/commit/123bb1af7bfae41d805337fef4b41045ef6c7d25)) 409* Let CMake automatically detect compiler flags 410* Add new compiler flags (`-Wundef`, `-Wswitch-default`, `-Wconversion`, `-fstack-protector-strong`) ([#98](https://github.com/DaveGamble/cJSON/pull/98)) 411* Change internal sizes from `int` to `size_t` ([ecd5678](https://github.com/DaveGamble/cJSON/commit/ecd5678527a6bc422da694e5be9e9979878fe6a0)) 412* Change internal strings from `char*` to `unsigned char*` ([28b9ba4](https://github.com/DaveGamble/cJSON/commit/28b9ba4334e0f7309e867e874a31f395c0ac2474)) 413* Add `const` in more places 414 4151.2.1 (Jan 31, 2017) 416===== 417Fixes: 418------ 419* Fixes a potential null pointer dereference in cJSON_Utils, discovered using clang's static analyzer by @bnason-nf, see [#96](https://github.com/DaveGamble/cJSON/issues/96) 420 4211.2.0 (Jan 9, 2017) 422===== 423Features: 424--------- 425* Add a new type of cJSON item for raw JSON and support printing it. Thanks @loigu, see [#65](https://github.com/DaveGamble/cJSON/pull/65), [#90](https://github.com/DaveGamble/cJSON/pull/90) 426 427Fixes: 428------ 429* Compiler warning if const is casted away, Thanks @gatzka, see [#83](https://github.com/DaveGamble/cJSON/pull/83) 430* Fix compile error with strict-overflow on PowerPC, see [#85](https://github.com/DaveGamble/cJSON/issues/85) 431* Fix typo in the README, thanks @MicroJoe, see [#88](https://github.com/DaveGamble/cJSON/pull/88) 432* Add compile flag for compatibility with C++ compilers 433 4341.1.0 (Dec 6, 2016) 435===== 436* Add a function `cJSON_PrintPreallocated` to print to a preallocated buffer, thanks @ChisholmKyle, see [#72](https://github.com/DaveGamble/cJSON/pull/72) 437* More compiler warnings when using Clang or GCC, thanks @gatzka, see [#75](https://github.com/DaveGamble/cJSON/pull/75), [#78](https://github.com/DaveGamble/cJSON/pull/78) 438* fixed a memory leak in `cJSON_Duplicate`, thanks @alperakcan, see [#81](https://github.com/DaveGamble/cJSON/pull/81) 439* fix the `ENABLE_CUSTOM_COMPILER_FLAGS` cmake option 440 4411.0.2 (Nov 25, 2016) 442===== 443* Rename internal boolean type, see [#71](https://github.com/DaveGamble/cJSON/issues/71). 444 4451.0.1 (Nov 20, 2016) 446===== 447Small bugfix release. 448* Fixes a bug with the use of the cJSON structs type in cJSON_Utils, see [d47339e](https://github.com/DaveGamble/cJSON/commit/d47339e2740360e6e0994527d5e4752007480f3a) 449* improve code readability 450* initialize all variables 451 4521.0.0 (Nov 17, 2016) 453===== 454This is the first official versioned release of cJSON.
