In entries where they were available before (like `/full/` namespace), those methods are available with fallbacks to old semantics (in addition to `Set`-like, they accept iterable objects). This behavior will be removed from the next major release - [Well-Formed Unicode Strings](https://togithub.com/tc39/proposal-is-usv-string) proposal: - Methods: - `String.prototype.isWellFormed` - `String.prototype.toWellFormed` - Moved to Stage 3, [November 2022 TC39 meeting](https://togithub.com/babel/proposals/issues/85#issuecomment-1332180862) - Added `/actual/` entries, disabled unconditional forced replacement - [Explicit resource management](https://togithub.com/tc39/proposal-explicit-resource-management) Stage 3 and [Async explicit resource management](https://togithub.com/tc39/proposal-async-explicit-resource-management) Stage 2 proposals: - Renamed from "`using` statement" and [splitted into 2 (sync and async) proposals](https://togithub.com/tc39/proposal-explicit-resource-management/pull/131) - In addition to already present well-known symbols, added new built-ins: - `Symbol.dispose` - `Symbol.asyncDispose` - `SuppressedError` - `DisposableStack` - `DisposableStack.prototype.dispose` - `DisposableStack.prototype.use` - `DisposableStack.prototype.adopt` - `DisposableStack.prototype.defer` - `DisposableStack.prototype.move` - `DisposableStack.prototype[@@dispose]` - `AsyncDisposableStack` - `AsyncDisposableStack.prototype.disposeAsync` - `AsyncDisposableStack.prototype.use` - `AsyncDisposableStack.prototype.adopt` - `AsyncDisposableStack.prototype.defer` - `AsyncDisposableStack.prototype.move` - `AsyncDisposableStack.prototype[@@asyncDispose]` - `Iterator.prototype[@@dispose]` - `AsyncIterator.prototype[@@asyncDispose]` - Sync version of this proposal moved to Stage 3, [November 2022 TC39 meeting](https://togithub.com/babel/proposals/issues/85#issuecomment-1333747094) - Added `/actual/` namespace entries for Stage 3 proposal - Added [`String.dedent` stage 2 proposal](https://togithub.com/tc39/proposal-string-dedent) - Method `String.dedent` - Throws an error on non-frozen raw templates for avoiding possible breaking changes in the future, [proposal-string-dedent/75](https://togithub.com/tc39/proposal-string-dedent/issues/75) - [Compat data targets](/packages/core-js-compat#targets-option) improvements: - [React Native from 0.70 shipped with Hermes as the default engine.](https://reactnative.dev/blog/2022/07/08/hermes-as-the-default) However, bundled Hermes versions differ from standalone Hermes releases. So added **`react-native`** target for React Native with bundled Hermes. - [According to the documentation](https://developer.oculus.com/documentation/web/browser-intro/), Oculus Browser was renamed to Meta Quest Browser, so `oculus` target was renamed to **`quest`**. - `opera_mobile` target name is confusing since it contains data for the Chromium-based Android version, but iOS Opera is Safari-based. So `opera_mobile` target was renamed to **`opera-android`**. - `android` target name is also confusing for someone - that means Android WebView, some think thinks that it's Chrome for Android, but they have some differences. For avoiding confusion, added **`chrome-android`** target. - For consistency with two previous cases, added **`firefox-android`** target. - For avoiding breaking changes, the `oculus` and `opera_mobile` fields are available in the compat data till the next major release. -

Ensured that polyfilled constructors `.prototype` is non-writable - Ensured that polyfilled methods `.prototype` is not defined - Added detection and fix of a V8 ~ Chrome <103 [bug](https://bugs.chromium.org/p/v8/issues/detail?id=12542) of `struturedClone` that returns `null` if cloned object contains multiple references to one error ### [`v3.22.4`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3224---20220503) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.22.3...v3.22.4) - Ensured proper `.length` of polyfilled functions even in compressed code (excepting some ancient engines) - Ensured proper `.name` of polyfilled accessors (excepting some ancient engines) - Ensured proper source / `ToString` conversion of polyfilled accessors - Actualized Rhino compat data - Refactoring ### [`v3.22.3`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3223---20220428) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.22.2...v3.22.3) - Added a fix for FF99+ `Array.prototype.includes` broken on sparse arrays ### [`v3.22.2`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3222---20220421) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.22.1...v3.22.2) - Fixed `URLSearchParams` in IE8- that was broken in the previous release - Fixed `__lookupGetter__` entries ### [`v3.22.1`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3221---20220420) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.22.0...v3.22.1) - Improved some cases of `RegExp` flags handling - Prevented experimental warning in NodeJS ~ 18.0 on detection `fetch` API - Added NodeJS 18.0 compat data ### [`v3.22.0`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3220---20220415) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.21.1...v3.22.0) - [Change `Array` by copy proposal](https://togithub.com/tc39/proposal-change-array-by-copy): - Moved to Stage 3, [March TC39 meeting](https://togithub.com/babel/proposals/issues/81#issuecomment-1083449843) - Disabled forced replacement and added `/actual/` entry points for methods from this proposal - `Array.prototype.toSpliced` throws a `TypeError` instead of `RangeError` if the result length is more than `MAX_SAFE_INTEGER`, [proposal-change-array-by-copy/70](https://togithub.com/tc39/proposal-change-array-by-copy/pull/70) - Added some more `atob` / `btoa` fixes: - NodeJS <17.9 `atob` does not ignore spaces, [node/42530](https://togithub.com/nodejs/node/issues/42530) - Actual NodeJS `atob` does not validate encoding, [node/42646](https://togithub.com/nodejs/node/issues/42646) - FF26- implementation does not properly convert argument to string - IE / Edge <16 implementation have wrong arity - Added `/full/` namespace as the replacement for `/features/` since it's more descriptive in context of the rest namespaces (`/es/` ⊆ `/stable/` ⊆ `/actual/` ⊆ `/full/`) - Avoided propagation of removed parts of proposals to upper stages. For example, `%TypedArray%.prototype.groupBy` was removed from the `Array` grouping proposal a long time ago. We can't completely remove this method since it's a breaking change. But this proposal has been promoted to stage 3 - so the proposal should be promoted without this method, this method should not be available in `/actual/` entries - but it should be available in early-stage entries to avoid breakage. - Significant internal refactoring and splitting of modules (but without exposing to public API since it will be a breaking change - it will be exposed in the next major version) - Bug fixes: - Fixed work of non-standard V8 `Error` features with wrapped `Error` constructors, [#1061](https://togithub.com/zloirock/core-js/issues/1061) - `null` and `undefined` allowed as the second argument of `structuredClone`, [#1056](https://togithub.com/zloirock/core-js/issues/1056) - Tooling: - Stabilized proposals are filtered out from the `core-js-compat` -> `core-js-builder` -> `core-js-bundle` output. That mean that if the output contains, for example, `es.object.has-own`, the legacy reference to it, `esnext.object.has-own`, no longer added. - Aligned modules filters of [`core-js-builder`](https://togithub.com/zloirock/core-js/tree/master/packages/core-js-builder) and [`core-js-compat`](https://togithub.com/zloirock/core-js/tree/master/packages/core-js-compat), now it's `modules` and `exclude` options - Added support of entry points, modules, regexes, and arrays of them to those filters - Missed `targets` option of `core-js-compat` means that the `targets` filter just will not be applied, so the result will contain modules required for all possible engines - Compat data: - `.stack` property on `DOMException` marked as supported from Deno [1.15](https://togithub.com/denoland/deno/releases/tag/v1.15.0) - Added Deno 1.21 compat data mapping - Added Electron 19.0 and updated 18.0 compat data mapping - Added Samsung Internet 17.0 compat data mapping - Added Opera Android 68 compat data mapping ### [`v3.21.1`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3211---20220217) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.21.0...v3.21.1) - Added a [bug](https://bugs.webkit.org/show_bug.cgi?id=236541)fix for the WebKit `Array.prototype.{ groupBy, groupByToMap }` implementation - `core-js-compat` targets parser transforms engine names to lower case - `atob` / `btoa` marked as [fixed](https://togithub.com/nodejs/node/pull/41478) in NodeJS 17.5 - Added Electron 18.0 compat data mapping - Added Deno 1.20 compat data mapping ### [`v3.21.0`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3210---20220202) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.20.3...v3.21.0) - Added [Base64 utility methods](https://developer.mozilla.org/en-US/docs/Glossary/Base64): - `atob` - `btoa` - Added the proper validation of arguments to some methods from web standards - Forced replacement of all features from early-stage proposals for avoiding possible web compatibility issues in the future - Added Rhino 1.7.14 compat data - Added Deno 1.19 compat data mapping - Added Opera Android 66 and 67 compat data mapping - Added iOS Safari 15.3 and 15.4 compat data mapping ### [`v3.20.3`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3203---20220115) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.20.2...v3.20.3) - Detects and replaces broken third-party `Function#bind` polyfills, uses only native `Function#bind` in the internals - `structuredClone` should throw an error if no arguments passed - Changed the structure of notes in `__core-js_shared__` ### [`v3.20.2`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3202---20220102) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.20.1...v3.20.2) - Added a fix of [a V8 ~ Chrome 36- `Object.{ defineProperty, defineProperties }` bug](https://bugs.chromium.org/p/v8/issues/detail?id=3334), [Babel issue](https://togithub.com/babel/babel/issues/14056) - Added fixes of some different `%TypedArray%.prototype.set` bugs, affects modern engines (like Chrome < 95 or Safari < 14.1) ### [`v3.20.1`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3201---20211223) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.20.0...v3.20.1) - Fixed the order of calling reactions of already fulfilled / rejected promises in `Promise.prototype.then`, [#1026](https://togithub.com/zloirock/core-js/issues/1026) - Fixed possible memory leak in specific promise chains - Fixed some missed dependencies of entries - Added Deno 1.18 compat data mapping ### [`v3.20.0`](https://togithub.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3200---20211216) [Compare Source](https://togithub.com/zloirock/core-js/compare/v3.19.3...v3.20.0) - Added `structuredClone` method [from the HTML spec](https://html.spec.whatwg.org/multipage/structured-data.html#dom-structuredclone), [see MDN](https://developer.mozilla.org/en-US/docs/Web/API/structuredClone) - Includes all cases of cloning and transferring of required ECMAScript and platform types that can be polyfilled, for the details see [the caveats](https://togithub.com/zloirock/core-js#caveats-when-using-structuredclone-polyfill) - Uses native structured cloning algorithm implementations where it's possible - Includes the new semantic of errors cloning from [`html/5749`](https://togithub.com/whatwg/html/pull/5749) - Added `DOMException` polyfill, [the Web IDL spec](https://webidl.spec.whatwg.org/#idl-DOMException), [see MDN](https://developer.mozilla.org/en-US/docs/Web/API/DOMException) - Includes `DOMException` and its attributes polyfills with fixes of many different engines bugs - Includes `DOMException#stack` property polyfill in engines that should have it - Reuses native `DOMException` implementations where it's possible (for example, in old NodeJS where it's not exposed as global) -
