Ciao Franco!
Thank you for your feedback, that would help tremendously, meanwhile, I also sent the question to the developers directly, via github, and this is what they had to say: that the updated SDK will be available by the end of the year and that it will also support TLS 1.3

best regards, and thank you again
Maurizio
