 ### Added
-- Added option to specify platform for dev command. Thanks to [@pylotlight](https://github.com/pylotlight) for the fix ([#3117](https://github.com/wailsapp/wails/pull/3117)). Based on the work of [@evsign](https://github.com/evsign) in [Draft PR](https://github.com/wailsapp/wails/pull/2724).
+
 - Added windows options supports `DisablePinchZoom` configuration. Added by @tuuzed in [PR](https://github.com/wailsapp/wails/pull/3115)
 - Add Apple Silicon hardware detection to `wails doctor`. Changed by @almas1992 in [PR](https://github.com/wailsapp/wails/pull/3129)
 - Remove quarantine attribute on macOS binaries. Changed by @leaanthony in [PR](https://github.com/wailsapp/wails/pull/3118)
