 - Why use `float64`? Can't we use `int`? 
   - Because JavaScript doesn't have a concept of `int`. Everything is a `number`, which translates to `float64` in Go. There are also restrictions on casting types in Go's reflection package, which means using `int` doesn't work. 
+
+### BackgroundColour
+
+In v2, this was a pointer to an `RGBA` struct. In v3, this is an `RGBA` struct value.
+
+### WindowIsTranslucent
+
+This flag has been removed. Now there is a `BackgroundType` flag that can be used to set the type of background the window should have.
+This flag can be set to any of the following values:
+- `BackgroundTypeSolid` - The window will have a solid background
+- `BackgroundTypeTransparent` - The window will have a transparent background
+- `BackgroundTypeTranslucent` - The window will have a translucent background
+
+On Windows, if the `BackgroundType` is set to `BackgroundTypeTranslucent`, the type of translucency can be set using the 
+`BackdropType` flag in the `WindowsWindow` options. This can be set to any of the following values:
+- `Auto` - The window will use an effect determined by the system
+- `None` - The window will have no background
+- `Mica` - The window will use the Mica effect
+- `Acrylic` - The window will use the acrylic effect
+- `Tabbed` - The window will use the tabbed effect
+
+
+## Windows Application Options
+
+### WndProcInterceptor
+
+If this is set, the WndProc will be intercepted and the function will be called. This allows you to handle Windows 
+messages directly. The function should have the following signature:
+
+```go
+func(hwnd uintptr, msg uint32, wParam, lParam uintptr) (returnValue uintptr, shouldReturn)
+```
+
+The `shouldReturn` value should be set to `true` if the returnValue should be returned by the main wndProc method. 
+If it is set to `false`, the return value will be ignored and the message will continue to be processed by the main 
+wndProc method.

 ## [Unreleased]
 
+### Breaking Changes
+
+- `wails dev` now uses the custom schemes `wails://` on macOS and Linux if Vite >= `v3.0.0` is used. This makes the dev application consistent in behaviour with the final production application and fixes some long-standing inconsistencies. Changed by @stffabi in [PR](https://github.com/wailsapp/wails/pull/2610)
+
 ### Added
 
 - Added Nodejs version in `wails doctor`. Added by @misitebao in [PR](https://github.com/wailsapp/wails/pull/2546)
 - Added support for WebKit2GTK 2.40+ on Linux. This brings additional features for the [AssetServer](/docs/reference/options#assetserver), like support for HTTP Request Bodies. The app must be compiled with the Go build tag `webkit2_40` to activate support for this features. This also bumps the minimum requirement of WebKit2GTK to 2.40 for your app. Added by @stffabi in this [PR](https://github.com/wailsapp/wails/pull/2592)
+- macOS: Added Window menu role with well known shortcuts "Minimize, Full-Screen and Zoom". Added by @stffabi in [PR](https://github.com/wailsapp/wails/pull/2586)
+- macOS: Added "Hide, Hide Others, Show All“ to appmenu. Added by @stffabi in [PR](https://github.com/wailsapp/wails/pull/2586)
