Rollup now requires at least Node 10 to run, or a sufficiently modern browser ([#​3346](https://togithub.com/rollup/rollup/issues/3346)) - The file structure of Rollup's ESM builds has changed: - The main ESM entry point is now at `rollup/dist/es/rollup.js` instead of `rollup/dist/rollup.es.js` - The ESM browser build is at `rollup/dist/es/rollup.browser.js` instead of `rollup/dist/rollup.browser.es.js` In general, the ESM builds now follow the same naming scheme as the CJS builds but are located in the `rollup/dist/es` subfolder instead of `rollup/dist` ([#​3391](https://togithub.com/rollup/rollup/issues/3391)) - The "watch.chokidar" option no longer accepts a `boolean` value but only an object of parameters that is passed to the bundled Chokidar instance. Chokidar installations by the user will be ignored in favour of the bundled instance ([#​3331](https://togithub.com/rollup/rollup/issues/3331)) - Modules that are completely tree-shaken will no longer be listed as part of any chunks in `generateBundle` - The `experimentalOptimizeChunks` and `chunkGroupingSize` options have been removed - [acorn](https://togithub.com/acornjs/acorn) plugins can only be used if they accept a passed-in acorn instance instead of importing it themselves. See [acornjs/acorn#​870 (comment)](https://togithub.com/acornjs/acorn/pull/870#issuecomment-527339830) for what needs to be done to make plugins compatible that do not support this yet ([#​3391](https://togithub.com/rollup/rollup/issues/3391)) - Emitted chunks now have the TypeScript type `Uint8Array` instead of `Buffer`. A `Buffer` can still be used, though ([#​3395](https://togithub.com/rollup/rollup/issues/3395)) - The TypeScript types no longer use ESTree types for AST nodes but a very generic type that does not contain information specific to certain node types ([#​3395](https://togithub.com/rollup/rollup/issues/3395)) - The signature of the `writeBundle` plugin hook has been changed to match `generateBundle`: The bundle object is now passed as second parameter instead of first and the first parameter is the output options ([#​3361](https://togithub.com/rollup/rollup/issues/3361)) - The following plugin hooks have been removed: - ongenerate: use `generateBundle` instead - onwrite: use `writeBundle` instead - transformBundle: use `renderChunk` instead - transformChunk: use `renderChunk` instead - You can no longer access `this.watcher` on the plugin context. - The `transform` hook can no longer return `dependencies`. - The `treeshake.pureExternalModules` option will now show a deprecation warning when used: use `treeshake.moduleSideEffects: 'no-external'` instead - Using `import.meta.ROLLUP_ASSET_URL_<..>` and `import.meta.ROLLUP_CHUNK_URL_<..>` in code will now show warnings: use `import.meta.ROLLUP_FILE_URL_<..>` instead - The `resolveAssetUrl` hook will now show a deprecation warning when used: use `resolveFileUrl` instead - The following plugin context functions will show warnings when used: - `this.emitAsset`: use `this.emitFile` - `this.emitChunk`: use `this.emitFile` - `this.getAssetFileName`: use `this.getFileName` - `this.getChunkFileName`: use `this.getFileName` - `this.isExternal`: use `this.resolve` - `this.resolveId`: use `this.resolve` - Directly adding properties to the bundle object in the `generateBundle` is deprecated will show a warning (removing properties is allowed, though): Use `this.emitFile` - Accessing `chunk.isAsset` on the bundle is deprecated: Use `chunk.type === 'asset'` instead - 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](https://togithub.com/rollup/rollup/issues/3393)) ##### Features - Rollup now bundles [Chokidar](https://togithub.com/paulmillr/chokidar) for a better watch experience ([#​3331](https://togithub.com/rollup/rollup/issues/3331)) - Rollup now bundles [acorn](https://togithub.com/acornjs/acorn) again, removing its only external dependency ([#​3391](https://togithub.com/rollup/rollup/issues/3391)) - Do not consider empty imports from side-effect-free modules for chunking and hoist side-effect imports if necessary ([#​3369](https://togithub.com/rollup/rollup/issues/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](https://togithub.com/rollup/rollup/issues/3391)) - `systemjs` can be used as format alias for `system` ([#​3381](https://togithub.com/rollup/rollup/issues/3381)) ##### Bug Fixes - Unknown output options now trigger a warning when using the JavaScript API ([#​3352](https://togithub.com/rollup/rollup/issues/3352)) - Rollup will no longer introduce Node types into TypeScript projects that do not use them ([#​3395](https://togithub.com/rollup/rollup/issues/3395)) - Generate correct sourcemaps when tree-shaking occurs in a multi-file bundle ([#​3423](https://togithub.com/rollup/rollup/issues/3423)) ##### Pull Requests - [#​3331](https://togithub.com/rollup/rollup/pull/3331): Bundle Chokidar ([@​lukastaegert](https://togithub.com/lukastaegert)) - [#​3343](https://togithub.com/rollup/rollup/pull/3343): Remove experimentalOptimizeChunks ([@​lukastaegert](https://togithub.com/lukastaegert)) - [#​3346](https://togithub.com/rollup/rollup/pull/3346): Update minimum required Node version to 10 ([@​lukastaegert](https://togithub.com/lukastaegert)) - [#​3352](https://togithub.com/rollup/rollup/pull/3352): Remove active deprecations ([@​lukastaegert](https://togithub.com/lukastaegert)) - [#​3361](https://togithub.com/rollup/rollup/pull/3361): Change writeBundle signature to match generateBundle ([@​lukastaegert](https://togithub.com/lukastaegert)) - [#​3369](https://togithub.com/rollup/rollup/pull/3369): Avoid empty imports from side-effect-free chunks ([@​lukastaegert](https://togithub.com/lukastaegert)) - [#​3381](https://togithub.com/rollup/rollup/pull/3381): Rename esm to es everywhere, add systemjs alias ([@​lukastaegert](https://togithub.com/lukastaegert)) - [#​3391](https://togithub.com/rollup/rollup/pull/3391): Bundle acorn, allow importing Rollup as Node ES module, update dependencies ([@​lukastaegert](https://togithub.com/lukastaegert)) - [#​3393](https://togithub.com/rollup/rollup/pull/3393): Better error code for name-less umd bundle ([@​rail44](https://togithub.com/rail44)) - [#​3395](https://togithub.com/rollup/rollup/pull/3395): Remove `@types` dependencies ([@​lukastaegert](https://togithub.com/lukastaegert)) - [#​3423](https://togithub.com/rollup/rollup/pull/3423): Update magic-string and fix sourcemaps ([@​lukastaegert](https://togithub.com/lukastaegert))
