-**vue-codemirror** v5 has been released, a new version based on [CodeMirorr@6](https://codemirror.net/6) and only available for Vue3; since CodeMirorr@6 is developed with native ES Modules, the new version will no longer support direct browser references to UMD modules; in short, the new version is **completely NOT compatible** with that of previous version. If you wish to continue using Vue2 or a lower version of CodeMirorr, please follow the legacy versions below.
