1.5.8
- Fix
make test in the Makefile, thanks @YanhaoMo for reporting this (#195)
1.5.7
Fixes:

- Fix a spelling mistake in the AFL fuzzer dictionary (#185), thanks @jwilk

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 (
cf9d57d56c)
- fix several potential issues found by Coverity
- fix potentially undefined behavior when assigning big numbers to
valueint (41e2837df1)
- 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 (87f77274de), this slightly changes the behavior, see commit message
Introduce unit tests
Started writing unit tests with the Cunity testing framework. Currently this covers the parser functions.
Also:
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 (0747669972)
- 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 (
9f6fa94c91)
- Combined
cJSON_AddItemToObject and cJSON_AddItemToObjectCS to one function (cf862d0fed)
Other changes
- Prevent the usage of incompatible C and header versions via preprocessor directive (
123bb1af7b)
- 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 (ecd5678527)
- Change internal strings from
char* to unsigned char* (28b9ba4334)
- Add
const in more places
