BeforeUnload version 0.1.0
null

BeforeUnload version 0.2.0
Adds client side API for disabling exit verification. Can be eg. used when force reloading page after connection error. https://github.com/alump/BeforeUnload/wiki/How-to-disable-verification-dialog-when-connection-error FYI, modern browsers do not anymore support custom messages, but dialog itself is still shown, with default confirmation message.

BeforeUnload version 0.3.0
0.3.0 version is now for Vaadin 8. As modern browsers do not anymore show the message given, has API been simplified to just have enabled / disabled actions. For Vaadin 7 users, use 0.2.x versions.
