Potential Actions Needed

1. To fully leverage new features in 3.4, it is recommended to also update the following dependencies when upgrading to 3.4:

   • Volar / vue-tsc@^1.8.27 (required)
   • @​vitejs/plugin-vue@​^5.0.0 (if using Vite)
   • nuxt@^3.9.0 (if using Nuxt)
   • vue-loader@^17.4.0 (if using webpack or vue-cli)

2. If using TSX with Vue, check actions needed in Removed: Global JSX Namespace.

3. Make sure you are no longer using any deprecated features (if you are, you should have warnings in the console telling you so). They may have been removed in 3.4.

BREAKING CHANGES

Global JSX Registration Removed

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 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.

Deprecated Features Removed

• Reactivity Transform 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.
• 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 instead.
