Hi all,

Last week, we shipped the first developer seed of iOS 12.2. Among other features, TLS 1.3 is now enabled by default for the entire system. All users of Network.framework and NSURLSession APIs will now negotiate TLS 1.3. The number of TLS 1.3 capable clients on the Internet should take quite a leap forward, and we are pleased to help move the needle towards faster and more secure network connections. 

We'd like to thank the members of this working group, and Eric Rescorla in particular, for all the work put into this protocol and its deployment on the Internet.

Enjoy!
