321 3221.3.2 (Mar 1, 2017) 323===== 324Fixes: 325------ 326* Don't build the unity library if testing is disabled, see [#121](https://github.com/DaveGamble/cJSON/pull/121). Thanks @ffontaine 327 3281.3.1 (Feb 27, 2017) 329===== 330Fixes: 331------ 332* 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. 333 3341.3.0 (Feb 17, 2017) 335===== 336This 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. 337 338Features: 339* New type for cJSON structs: `cJSON_Invalid`, see [#108](https://github.com/DaveGamble/cJSON/pull/108) 340 341Fixes: 342------ 343* runtime checks for a lot of potential integer overflows 344* fix incorrect return in cJSON_PrintBuffered [cf9d57d](https://github.com/DaveGamble/cJSON/commit/cf9d57d56cac21fc59465b8d26cf29bf6d2a87b3) 345* fix several potential issues found by [Coverity](https://scan.coverity.com/projects/cjson) 346* fix potentially undefined behavior when assigning big numbers to `valueint` ([41e2837](https://github.com/DaveGamble/cJSON/commit/41e2837df1b1091643aff073f2313f6ff3cc10f4)) 347 * 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). 348 * fix the `cJSON_SetNumberValue` macro ([87f7727](https://github.com/DaveGamble/cJSON/commit/87f77274de6b3af00fb9b9a7f3b900ef382296c2)), this slightly changes the behavior, see commit message 349 350Introduce unit tests 351-------------------- 352 353* Started writing unit tests with the [Cunity](https://github.com/ThrowTheSwitch/Unity) testing framework. Currently this covers the parser functions. 354 355Also: 356* Support for running the tests with [Valgrind](http://valgrind.org) 357* Support for compiling the tests with [AddressSanitizer](https://github.com/google/sanitizers) and [UndefinedBehaviorSanitizer](https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html). 358* `travis.yml` file for running unit tests on travis. (not enabled for the repository yet though [#102](https://github.com/DaveGamble/cJSON/issues/102) 359 360Simplifications 361--------------- 362 363After 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. 364* Use `strtod` from the standard library for parsing numbers ([0747669](https://github.com/DaveGamble/cJSON/commit/074766997246481dfc72bfa78f07898a2716473f)) 365* Use goto-fail in several parser functions ([#100](https://github.com/DaveGamble/cJSON/pull/100)) 366* 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)) 367* Simplify the buffer allocation strategy to always doubling the needed amount ([9f6fa94](https://github.com/DaveGamble/cJSON/commit/9f6fa94c91a87b71e4c6868dbf2ce431a48517b0)) 368* Combined `cJSON_AddItemToObject` and `cJSON_AddItemToObjectCS` to one function ([cf862d](https://github.com/DaveGamble/cJSON/commit/cf862d0fed7f9407e4b046d78d3d8050d2080d12)) 369 370Other changes 371------------- 372* Prevent the usage of incompatible C and header versions via preprocessor directive ([123bb1](https://github.com/DaveGamble/cJSON/commit/123bb1af7bfae41d805337fef4b41045ef6c7d25)) 373* Let CMake automatically detect compiler flags 374* Add new compiler flags (`-Wundef`, `-Wswitch-default`, `-Wconversion`, `-fstack-protector-strong`) ([#98](https://github.com/DaveGamble/cJSON/pull/98)) 375* Change internal sizes from `int` to `size_t` ([ecd5678](https://github.com/DaveGamble/cJSON/commit/ecd5678527a6bc422da694e5be9e9979878fe6a0)) 376* Change internal strings from `char*` to `unsigned char*` ([28b9ba4](https://github.com/DaveGamble/cJSON/commit/28b9ba4334e0f7309e867e874a31f395c0ac2474)) 377* Add `const` in more places 378 3791.2.1 (Jan 31, 2017) 380===== 381Fixes: 382------ 383* 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) 384 3851.2.0 (Jan 9, 2017) 386===== 387Features: 388--------- 389* 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) 390 391Fixes: 392------ 393* Compiler warning if const is casted away, Thanks @gatzka, see [#83](https://github.com/DaveGamble/cJSON/pull/83) 394* Fix compile error with strict-overflow on PowerPC, see [#85](https://github.com/DaveGamble/cJSON/issues/85) 395* Fix typo in the README, thanks @MicroJoe, see [#88](https://github.com/DaveGamble/cJSON/pull/88) 396* Add compile flag for compatibility with C++ compilers 397 3981.1.0 (Dec 6, 2016) 399===== 400* Add a function `cJSON_PrintPreallocated` to print to a preallocated buffer, thanks @ChisholmKyle, see [#72](https://github.com/DaveGamble/cJSON/pull/72) 401* 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) 402* fixed a memory leak in `cJSON_Duplicate`, thanks @alperakcan, see [#81](https://github.com/DaveGamble/cJSON/pull/81) 403* fix the `ENABLE_CUSTOM_COMPILER_FLAGS` cmake option 404 4051.0.2 (Nov 25, 2016) 406===== 407* Rename internal boolean type, see [#71](https://github.com/DaveGamble/cJSON/issues/71). 408 4091.0.1 (Nov 20, 2016) 410===== 411Small bugfix release. 412* Fixes a bug with the use of the cJSON structs type in cJSON_Utils, see [d47339e](https://github.com/DaveGamble/cJSON/commit/d47339e2740360e6e0994527d5e4752007480f3a) 413* improve code readability 414* initialize all variables 415 4161.0.0 (Nov 17, 2016) 417===== 418This is the first official versioned release of cJSON. It provides an API version for the shared library and improved Makefile and CMake build files. 419
