+1.7.12
+======
+Fixes:
+------
+* Fix infinite loop in `cJSON_Minify` (potential Denial of Service), thanks @Alanscut for reporting. See #354
+* Fix link error for Visual Studio. Thanks @tan-wei, see #352
+* Undefine `true` and `false` for `cJSON_Utils` before redefining them. Thanks @raiden00pl, see #347
+
+
+1.7.11
+======
+Fixes:
+------
+* Fix a bug where cJSON_Minify could overflow it's buffer, both reading and writing. This is a security issue. (see #338). Big thanks @bigric3 for reporting.
+* Unset `true` and `false` macros before setting them if they exist. See #339, thanks @raiden00pl for reporting
+
+1.7.10
+======
+Fixes:
+------
+* Fix package config file for `libcjson`. Thanks @shiluotang for reporting (#321)
+* Correctly split lists in `cJSON_Utils`'s merge sort. Thanks @andysCaplin for the fix (#322)
+
+1.7.9
+=====
+Fixes:
+------
+* Fix a bug where `cJSON_GetObjectItemCaseSensitive` would pass a nullpointer to `strcmp` when called on an array (#315). Thanks @yuweol for reporting.
+* Fix error in `cJSON_Utils` where the case sensitivity was not respected (#317). Thanks @yuta-oxo for fixing.
+* Fix some warnings detected by the Visual Studio Static Analyzer (#307). Thanks @bnason-nf
+
+1.7.8
+=====
+Fixes:
+------
+* cJSON now works with the `__stdcall` calling convention on Windows, see #295, thanks @zhindes for contributing
