BoringSSL
BoringSSL is a fork of OpenSSL that is designed to meet Google’s needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don’t recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Swift Package Manager
A new Swift package was created to build static and dynamic libraries with Xcode / SwiftPM.
