 ### Support for older Swift versions
 
-Earlier versions of SwiftNIO (2.39.x and lower) and SwiftNIOExtras (1.10.x and lower) supported Swift 5.2 and 5.3, SwiftNIO (2.29.x and lower) and SwiftNIOExtras (1.9.x and lower) supported Swift 5.0 and 5.1. 
+The most recent versions of SwiftNIO Extras support Swift 5.5 and newer. The minimum Swift version supported by SwiftNIO Extras releases are detailed below:
+
+SwiftNIO Extras     | Minimum Swift Version
+--------------------|----------------------
+`1.0.0 ..< 1.10.0`  | 5.0
+`1.10.0 ..< 1.11.0` | 5.2
+`1.11.0 ..< 1.14.0` | 5.4
+`1.14.0 ...`        | 5.5
 
 On the [`nio-extras-0.1`](https://github.com/apple/swift-nio-extras/tree/nio-extras-0.1) branch, you can find the `swift-nio-extras` version for the SwiftNIO 1 family. It requires Swift 4.1 or better.
