+
+Added uninstaller icon and uninstaller header image support for NSIS installer.
+
+Notes:
+
+- For `tauri-bundler` lib users, the `NsisSettings` now has 2 new fields `uninstaller_icon` and `uninstaller_header_image` which can be a breaking change
+- When bundling with NSIS, users can add `uninstallerIcon` and `uninstallerHeaderImage` under `bundle > windows > nsis` to configure them.
