-### BREAKING CHANGES
+### Note on JSX Types Change
 
-* 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.
+* In the next minor (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.
 
-  For TSX users, the old global behavior can be enabled by explicitly importing or referencing `vue/jsx`. Alternatively, the user can set [jsxImportSource](https://www.typescriptlang.org/tsconfig#jsxImportSource) to `'vue'` in `tsconfig.json`, or opt-in per file with `/* @jsxImportSource vue */`.
+  For TSX users, it is suggested to set [jsxImportSource](https://www.typescriptlang.org/tsconfig#jsxImportSource) to `'vue'` in `tsconfig.json` after upgrading to 3.3, or opt-in per file with `/* @jsxImportSource vue */`. This will allow you to opt-in to the new behavior now and upgrade seamlessly when 3.4 releases.
 
-  Note 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).
+  If there is code that depends on the presence of the global `JSX` namespace,  you can retain the exact pre-3.4 global behavior by explicitly referencing `vue/jsx`, which registers the global `JSX` namespace.
+
+  Note that the planned change in 3.4 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).
