+### BREAKING CHANGES
+
+#### General Changes
+
+- The minimal required Node version is now 18.0.0 (#5142)
+- The browser build now relies on a WASM artifact that needs to be provided as well (#5073)
+- The NodeJS build now relies on an optional native binary; for unsupported platforms, users can use the `@rollup/wasm-node` package that has the same interface as Rollup but relies on WASM artifacts (#5073)
+- The "with" syntax for import attributes is not yet supported, awaiting support in SWC (#5073)
+- The `INVALID_IMPORT_ASSERTION` error code has been replaced with `INVALID_IMPORT_ATTRIBUTE` (#5073)
+- Rollup will now warn for `@__PURE__` and `@__NO_SIDE_EFFECTS__` annotations in invalid locations (#5165)
+- If an entry module starts with a shebang comment `#!...`, this comment will be prepended to the output for `es` and `cjs` formats (#5163)
+- File hashes will now use url-safe base64 encoded hashes (#5155)
+- The maximum hash length has been reduced to 22 characters (#5155)
+- The `RollupWarning` type has been removed in favor of the `RollupLog` type (#5147)
+
+#### Changes to Rollup Options
+
+- Acorn plugins are no longer supported, the `acornInjectPlugins` option has been removed (#5073)
+- The `acorn` option has been removed (#5073)
+- `output.externalImportAssertions` has been deprecated in favor of `output.externalImportAttributes` (#5073)
+- `inlineDynamicImports`, `manualChunks` and `preserveModules` have been removed on input option level: Please use the corresponding output options of the same names (#5143)
+- Removed output options (#5143):
+  - `output.experimentalDeepDynamicChunkOptimization`: This option is no longer needed as Rollup now always runs the full chunking algorithm
+  - `output.dynamicImportFunction`: Use the `renderDynamicImport` plugin hook instead
+  - `output.namespaceToStringTag`: Use `output.generatedCode.symbols` instead
+  - `output.preferConst`: Use `output.generatedCode.constBindings` instead
+
+#### Plugin API Changes
+
+- For `this.resolve`, the default of the `skipSelf` option is now `true` (#5142)
+- `this.parse` now only supports the `allowReturnOutsideFunction` option for now (#5073)
+- Import assertions now use the [new import attribute AST structure](https://github.com/estree/estree/blob/master/experimental/import-attributes.md) (#5073)
+- "assertions" have been replaced with "attributes" in various places of the plugin interface (#5073)
+- If the import of a module id is handled by the `load` hook of a plugin, `rollup.watch` no longer watches the actual file if the module id corresponds to a real path; if this is intended, then the plugin is responsible for calling `this.addWatchFile` for any dependency files (#5150)
+- The normalized input options provided by `buildStart` and other hooks no longer contain an `onwarn` handler; plugins should use `onLog` instead (#5147)
+- `this.moduleIds` has been removed from the plugin context: Use `this.getModuleIds()` instead (#5143)
+- The `hasModuleSideEffects` flag has been removed from the `ModuleInfo` returned by `thi s.getModuleInfo()`: Use `moduleSideEffects` on the `ModuleInfo` instead (#5143)
+
+### Features
+
+- Improve parsing speed by switching to a native SWC-based parser (#5073)
+- Rollup will now warn for `@__PURE__` and `@__NO_SIDE_EFFECTS__` annotations in invalid locations (#5165)
+- The parser is now exposed as a separate export `parseAst` (#5169)
+
+### Bug Fixes
+
+- Rollup no longer tries to watch virtual files if their name corresponds to an actual file name; instead, plugins handle watching via `this.addWatchFile()` (#5150)
+
