Hey, what an amazing week! Just got back home from VueConf.us. It was such a great conference. Interesting presentations, amazing people and so much [fun](https://twitter.com/jenlooper/status/1111353454465830912) in general. 🦄💃 As for news: The new 5.0 version of Vue.js Devtools has been released! It comes with 2 new tabs – routing and performance, which allows you to measure your application for potential bottlenecks. It also ships with dark mode support 🌒. Also, there are 2 RFCs to Vue: One is the [advanced reactivity API](https://github.com/vuejs/rfcs/pull/22), which I’m extremely excited about. It should allow you to create observable objects, watchers and computed properties, without actually creating a new Vue instance. This might prove extremely useful, especially for library authors. I imagine Vuelidate could benefit from it a lot. The 2nd RFC is about [dynamic lifecycle hooks injection](https://github.com/vuejs/rfcs/pull/23). This should make it possible for you to conditionally add or remove lifecycle hooks within your component’s code. Oh, and [12 talks from Vue.js Amsterdam](https://www.youtube.com/playlist?list=PLCxzy-hmQq9ECHOwbRrbBx0VEoqWM02CA&utm_campaign=Vue.js%20News&utm_medium=email&utm_source=Revue%20newsletter) are already available.
