SwiftNIO 2.41.1

SemVer Patch

• Fix compilation with Swift 5.5.0 and 5.5.1 (#2234)

SwiftNIO 2.41.0

Highlights

This release fully adopts Sendable in all libraries. In minimal concurrency checking mode (i.e. without -warn-concurrency) this should not produce any Sendable errors in your code as we have used @preconccurency to give adopters time to comply to the sendability rules. Many conformances are only available in Swift 5.7 though. Note that swift-nio itself currently does not compile successfully with strict concurrency checking turned on (with -warn-concurrency).

Please file an issue if your code no longer compiles because of Sendable errors.
