- New versions of methods are implemented as new modules and available in new entries or entries where old versions of methods were not available before (like `/actual/` namespace)
- 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

- [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.

[Compare Source](https://github.com/zloirock/core-js/compare/v3.25.3...v3.25.4)
- Added a workaround of a Nashorn bug with `Function.prototype.{ call, apply, bind }` on string methods, [#​1128](https://github.com/zloirock/core-js/issues/1128)

[Compare Source](https://github.com/zloirock/core-js/compare/v3.25.1...v3.25.2)
- Considering `document.all` as a callable in some missed cases

### [`v3.25.1`](https://github.com/zloirock/core-js/blob/HEAD/CHANGELOG.md#3251---20220908)
[Compare Source](https://github.com/zloirock/core-js/compare/v3.25.0...v3.25.1)
- Added some fixes and workarounds of FF30- typed arrays bug that does not properly convert objects to numbers
- Added `sideEffects` field to `core-js-pure` `package.json` for better tree shaking, [#​1117](https://github.com/zloirock/core-js/issues/1117)
- Dropped `semver` dependency from `core-js-compat`
- `semver` package (ironically) added [a breaking change and dropped NodeJS 8 support in the minor `7.1` version](https://github.com/npm/node-semver/commit/d61f828e64260a0a097f26210f5500), after that `semver` in `core-js-compat` was pinned to `7.0` since for avoiding breaking changes it should support NodeJS 8. However, since `core-js-compat` is usually used with other packages that use `semver` dependency, it causes multiple duplication of `semver` in dependencies. So I decided to remove `semver` dependency and replace it with a couple of simple helpers.
- Added Bun 0.1.6-0.1.11 compat data

- Added [`Object.prototype.__proto__`](https://tc39.es/ecma262/#sec-object.prototype.\__proto\_\_) polyfill
- It's optional, legacy, and in some cases (mainly because of developers' mistakes) can cause problems, but [some libraries depend on it](https://github.com/denoland/deno/issues/13321), and most code can't work without the proper libraries' ecosystem
- Only for modern engines where this feature is missed (like Deno), it's not installed in IE10- since here we have no proper way setting of the prototype
- Without fixes of early implementations where it's not an accessor since those fixes are impossible
- Only for the global version
- Considering `document.all` as an object in some missed cases, see [ECMAScript Annex B 3.6](https://tc39.es/ecma262/#sec-IsHTMLDDA-internal-slot)
- Avoiding unnecessary promise creation and validation result in `%WrapForValid(Async)IteratorPrototype%.return`, [proposal-iterator-helpers/215](https://github.com/tc39/proposal-iterator-helpers/pull/215)

- [Change `Array` by copy proposal](https://github.com/tc39/proposal-change-array-by-copy):
- Moved to Stage 3, [March TC39 meeting](https://github.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://github.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://github.com/nodejs/node/issues/42530)
- Actual NodeJS `atob` does not validate encoding, [node/42646](https://github.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://github.com/zloirock/core-js/issues/1061)
- `null` and `undefined` allowed as the second argument of `structuredClone`, [#​1056](https://github.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://github.com/zloirock/core-js/tree/master/packages/core-js-builder) and [`core-js-compat`](https://github.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://github.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
