The following warnings and errors occur with Vue 3.0.0:

[MohammedElkashef]

Property "$createElement" was accessed during render but is not defined on instance.
Property "_self" was accessed during render but is not defined on instance.
Unhandled error during execution of render function.
Unhandled error during execution of scheduler flush. This is likely a Vue internals bug. Please open an issue at https://new-issue.vuejs.org/?repo=vuejs/vue-next.
Uncaught (in promise) TypeError: Cannot read property '_c' of undefined.

Adding support for the very recently released Vue 3.0.0 would be amazing!
