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 plugins can only be used if they accept a passed-in acorn instance instead of importing it themselves. See acornjs/acorn#​870 (comment) 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
