New release of AWS IoT Device SDK for Embedded C simplifies authentication and provisioning of IoT devices

AWS IoT Device SDK for Embedded C (C-SDK) release 202108.00 includes the AWS SigV4 library and a refactored AWS IoT Fleet Provisioning client library for IoT applications. This release makes it easier for developers using C-SDK to authenticate inbound API requests to AWS services from IoT devices running HTTP, and provision IoT devices that do not have unique certificates.
