+* cJSON library version is upgraded to 1.7.18.
+* Minimum required OpenSSL version is updated to 3.0.13 for users using OpenSSL as security library.
+* Minimum required libCurl version is updated to 8.6.0 for users using libCurl as http client.
+* QuoVadis Root CA 2 G3" certificate will be retired on 2024-10-15T04:00:00.000Z hence code examples are updated to use existing certificate as well as new certificate i.e. "DigiCert Global Root G2".

To understand more on Trusted Certificate Store, refer the [openssl documentation](https://docs.openssl.org/master/man7/ossl-guide-tls-introduction/#trusted-certificate-store).
