Full Changelog: 2.78.0...2.79.0

SwiftNIO 2.78.0

What's Changed

This release contains a number of features that have been added to enable the SwiftNIO ecosystem to adopt strict concurrency checking and the Swift 6 language mode more easily. In particular, this release migrates NIOCore and NIOEmbedded, two critical and widespread dependencies.

This release also contains new tools for making adoption easier, in particular the isolated views of EventLoop, EventLoopPromise, and EventLoopFuture. For more details on how to use these types to make adoption of strict concurrency easier, please see our documentation on the relationship between EventLoops, EventLoopFutures, and Swift's concurrency model.

More work in this area is ongoing, and will be released in subsequent versions.
