(My guess is that most would-be DTLS 1.3 implementors are off working on QUIC; that’s certainly the case of OpenSSL.)
My guess is that many companies, which have been interested in secure IoT device communication, are now focus on AI and not QUIC. For hobby developers it maybe a little too much work, to implement DTLS 1.3 in the free time. But that also applies for DTLS 1.2 extensions with higher development effort, not only for a general switch to DTLS 1.3. best regards Achim _______________________________________________ TLS mailing list TLS@ietf.org https://www.ietf.org/mailman/listinfo/tls
