 ### New Features
 
-* **Dynamic Updates and Validation** - Checkout the [README](https://github.com/chriskiehl/Gooey/blob/master/README.md) for details on how to get started. This feature is really hairy behind the scenes and involves all kinds of crazy monkey patching in order to work. Odds of encountering a bug or scenario that doesn't work for your use case is high in this initial release. Please fill out an issue if any problems pop up!

 * **Graceful Shutdown control** - Gooey previously would `SIGTERM` your application when you tried to halt it while running. However, with 1.2.0, you have control over which signal Gooey sends when you request a shutdown. This gives you a chance to catch that signal and clean up and resources currently un use before shutting down.
 * **Better sys.argv handling** - Gooey no longer mutates the global sys.argv variable. This caused people all kinds of problems -- most frequent being Gooey spawning multiple windows. This is now removed, and hopefully all the pain stemming from it as well.
