• All planned RFCs have been merged.

• All merged RFCs have been implemented.

• Vue CLI now has experimental support via vue-cli-plugin-vue-next.

• There is also a simple plain webpack-based setup with Single-File Component support available here.

Please note that there could still be undocumented behavior inconsistencies with 2.x. When you run into such a case, please make sure to first check if the behavior difference has already been proposed in an existing RFC. If the inconsistency is not part of an RFC, then it's likely unintended, and an issue should be opened (please make sure to use the issue helper when opening new issues).

In addition, the current implementation requires native ES2015+ in the runtime environment and does not support IE11 (yet). The IE11 compatible build will be worked on after we have reached RC stage.

The only difference between Vuex 4.0 and 3.x is that it's Vue 3 compatible! It is ready to enter RC together with Vue 3 core.

As of v4.5.0, vue-cli now provides built-in option to choose Vue 3 preset when creating a new project.

There are currently two JSX transform implementations for Vue 3 with slightly differing syntax (for Vue specific features):

• vueComponent/jsx
• HcySunYang/vue-next-jsx

We are using this thread to unify the design and land on an official specification of how Vue features should be handled in JSX. If you use Vue with JSX, please provide your feedback in that thread.
