FreeRTOS version 202011.00 is now available with refactored IoT and AWS libraries: coreMQTT, coreJSON, corePKCS11, and AWS IoT Device Shadow, in addition to the FreeRTOS kernel and FreeRTOS+TCP library. These refactored libraries have been optimized for modularity and memory usage for constrained microcontrollers, and have undergone code quality checks (e.g. MISRA-C compliance, Coverity static analysis), and memory safety validation with the C Bounded Model Checker (CBMC) automated reasoning tool. For more details on these libraries and other features of this release, see the 202011.00 release blog on
