The biggest new feature in this commit is the addition of NativeMessageBox::scopedAsync and AlertWindow::scopedAsync, both of which return an instance of ScopedMessageBox that will hide the message box in its destructor. The code for displaying modal dialogs on Windows has also been updated. Now, the dialog itself is run from a new thread with its own message loop. This means that when the dialog is dismissed, the background thread can be joined safely. In plugins, this means that there's no danger of the plugin view being destroyed from within the message box runloop, for example.
