Starting in 3.4, Vue no longer registers the global `JSX` namespace by default. This is necessary to avoid global namespace collision with React so that TSX of both libs can co-exist in the same project. This should not affect SFC-only users with latest version of Volar.
If you are using TSX, there are two options:
1. Explicitly set [jsxImportSource](https://www.typescriptlang.org/tsconfig#jsxImportSource) to `'vue'` in `tsconfig.json` before upgrading to 3.4. You can also opt-in per file by adding a `/* @jsxImportSource vue */` comment at the top of the file.
2. If you have code that depends on the presence of the global `JSX` namespace, e.g. usage of types like `JSX.Element` etc., you can retain the exact pre-3.4 global behavior by explicitly referencing `vue/jsx`, which registers the global `JSX` namespace.
Note that this is a type-only breaking change in a minor release, which adheres to our [release policy](https://vuejs.org/about/releases.html#semantic-versioning-edge-cases).
#### Deprecated Features Removed
- [Reactivity Transform](https://vuejs.org/guide/extras/reactivity-transform.html) was marked deprecated in 3.3 and is now removed in 3.4. This change does not require a major due to the feature being experimental. Users who wish to continue using the feature can do so via the [Vue Macros plugin](https://vue-macros.dev/features/reactivity-transform.html).
-`app.config.unwrapInjectedRef` has been removed. It was deprecated and enabled by default in 3.3. In 3.4 it is no longer possible to disable this behavior.
-`@vnodeXXX` event listeners in templates are now a compiler error instead of a deprecation warning. Use `@vue:XXX` listeners instead.
-`v-is` directive has been removed. It was deprecated in 3.3. Use the [`is` attribute with `vue:` prefix](https://vuejs.org/api/built-in-special-attributes.html#is) instead.
