 * Do not consider empty imports from side-effect-free modules for chunking and hoist side-effect imports if necessary (#3369)
 * Rollup can now be imported as an ES module in Node via `import {rollup} from 'rollup'`. Note that this relies on Node's experimental [conditional package exports](https://nodejs.org/dist/latest-v13.x/docs/api/esm.html#esm_conditional_exports) feature and is therefore itself experimental (#3391)
 * `systemjs` can be used as format alias for `system` (#3381)
+* The error code for a missing `name` property when targeting UMD has been changed to `MISSING_NAME_OPTION_FOR_IIFE_EXPORT` to emphasize this is needed for the IIFE part of UMD (#3393)
 
 ### Bug Fixes
 * Unknown output options now trigger a warning when using the JavaScript API (#3352)
