+- Updated the underlying Tauri framework from version 1 to the latest version 2. Please do not install this prerelease manually. Production versions such as v26.4.1 will ignore this update. We are using this prerelease to test the clean update path for the migration from the Tauri v1 framework to the Tauri v2 framework. After a successful test, this prerelease will be removed.
