 - Suggest "Open Documentation" when toolchain not found ([#1939](https://github.com/swiftlang/vscode-swift/pull/1939))
-- Fix colorization of standard swift-testing test runs ([#1933](https://github.com/swiftlang/vscode-swift/pull/1933))
 - Make sure all folder operation listeners get past folder add events ([#1945](https://github.com/swiftlang/vscode-swift/pull/1945))
