 ### Specify a Swift version
 
-The buildpack defaults to Swift 5.9 and will be updated when new Swift versions are released.
+The buildpack defaults to Swift 5.9.1 and will be updated when new Swift versions are released.
 
 If you need to use a specific version of the Swift toolchain, including older versions – for example Swift 4.2.x to retain compatibility with Swift 3 projects, or a previous version as you run into issues with the latest – you can pin any version number using a file called `.swift-version` in the root of the project folder, or by setting a `SWIFT_VERSION` configuration variable on Heroku, then deploying again.
