When will this be in production? I'm working on a custom titlebar and this is the second last piece of perfection.

Also how do I disable the native title bar? I have decorations set to false.

appWindow.title().then(title => {
      if (windowTitle !== title) setWindowTitle(title);
    });

I updated cargo.toml, and still same error. Does it work for you guys?

Seems like the other plugins like tauri-plugin-window-state and tauri-plugin-store and tauri-plugin-single-instance depend on 1.2.5?

Had to set tauri = { version = "1.3",

Nope, they only specify "1", so if we ignore the fact that some plugins use apis introduced in 1.1 and 1.2 the plugins don't care about the minor version and a simple cargo update is supposed to update it (adding 1.3 in your cargo.toml file is basically the same in this context since it tells cargo to upgrade to at least 1.3)
