It turns out, I do get those updates about 3.2 on a regular basis. The feed that I use is Evan’s Twitter. Thanks for coming to my TED Talk.” — @halftes6 [0:02:12] “Shadow DOM is a concept that's been introduced that allows you to have your own private document object model that you can manipulate. This has actually been in use by browsers for years, but now they've exposed it to JavaScript developers to be able to use it themselves.” — @fimion [0:07:40] “You can progressively add it and then once enough things have Vue 3 support, you just turn it over to Vue 3, and it should all just work.” — @fimion [0:12:33] “Vuetify incidentally, is one project whose release notes I do read. I get Vuetify release notes and I get Cypress release notes. I'm always excited about both because I'm looking for the new stuff that we can now start to do.” — @marktnoonan [0:12:45] “The primary thing that you cannot do with a custom element that you can do in Vue with a proper Vue component is scoped slots, which is our favorite topic on this podcast.” — @fimion [0:14:45] “It's good to stay on top of these things, and at least be aware of various options that you have in the ecosystem. Knowing what's coming up in newer versions is always better for everyone as maybe finally, that thing that you want fixed has been fixed.” — @fimion [0:21:08] Links Mentioned in Today’s Episode: Vue 3.2 changelog Vue 3.2 project board RFC the Vue: Script Setup with Lachlan Miller (RFCs 227 & 228) Vue Demi, Anthony Fu @MarkTNoonan Streets of Rage 4, Dotemu (Nintendo Switch, PlayStation 4, Xbox One, Steam (Windows, Mac, Linux), GOG, Humble) VirtualCoffee Dragon Age: Inquisition, EA (PlayStation 4, Xbox One, PlayStation 3, Xbox 360, Microsoft Windows) Special Guest: Mark Noonan.Support Enjoy the Vue
