## 2.0.0
*2020-03-06*

### Breaking Changes
* Rollup now requires at least Node 10 to run, or a sufficiently modern browser (#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)
* 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)
* 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://github.com/acornjs/acorn) plugins can only be used if they accept a passed-in acorn instance instead of importing it themselves. See https://github.com/acornjs/acorn/pull/870#issuecomment-527339830 for what needs to be done to make plugins compatible that do not support this yet (#3391)
* Emitted chunks now have the TypeScript type `Uint8Array` instead of `Buffer`. A `Buffer` can still be used, though (#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)
* 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)
* 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)

### Features
* Rollup now bundles [Chokidar](https://github.com/paulmillr/chokidar) for a better watch experience (#3331)
* Rollup now bundles [acorn](https://github.com/acornjs/acorn) again, removing its only external dependency (#3391)
* 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)

### Bug Fixes
* Unknown output options now trigger a warning when using the JavaScript API (#3352)
* Rollup will no longer introduce Node types into TypeScript projects that do not use them (#3395)
* Generate correct sourcemaps when tree-shaking occurs in a multi-file bundle (#3423)
